I have 1 month left on my AAMCO rebuilt transmission. I took it in a few weeks ago when it went into "limp mode" (Stuck in 1st gear). Eventually, they got an error code of P0730, which I believe is electrical-related. All was pretty good but then today, driving @ high speed on the interstate, I could not get into 4th gear...
View 1 RepliesSo yesterday, this had happened for the third time in 3 years owning this car. Unhooking the battery for 20-30 minutes resets the computer and it is ready to go for a while with no issues. This has become annoying though. What is causing the car to enter "limp" mode and stay in third gear? One time it happened, I brought it to AutoZone and they did a scan and came up with the speed sensor. I haven't replaced it because it didn't happen for a while after that.
View 11 RepliesJust picked up a 2002 golf 2.0 auto for $200. Get the car home start it up and it runs great but... transmission shifts all kinds of funky. Starts in first then shifts to third. If I give it some gas it shifts down to second but has nothing there, just revs. Will not go into 4th at all. Throw my little mac scanner on it some codes come up. Only one that mattered was p0277 if I remember. Do a little search and it comes up as the g68 under the tranny mount. Change that out and had not cel. Still shifting the same but no code at all. Throw my scanner on just to see and get p0730 incorrect gear ratio.
View 2 RepliesDamn car is stuck in 3rd gear! Hooked up scanner and the screen just says error! I have to keep the scanner in the vehicle, hooked up, just to drive the car. That's just so it'll shift as its supposed to! Now it's not letting me pull the code out, in order for me to erase it! It just keeps saying "error".
View 1 RepliesI have a Korean spec 2014 Hyundai Santa Fe 2.2L R-eVGT 6AT 4WD. Around a year ago it started to go into limp mode i had it checked and the error code was p0488 (EGR) Throttle Control Circuit A Range / Performance.
It has gradually become more frequent to the extent it goes into limp mode within a a minute or so . so far the dealer has changed the EGR valve, TCM , the whole turbo assembly and it is no different. They have also stripped and cleaned the intake manifold and egr cooler.
My tranny is stuck in limp mode. I can manually shift it, but it won't shift on it's own. The 'automatic' part of the automatic transimission is definitely not working right.
I searched and checked for the usual suspects, low battery or alternator output (measured over 14v at batt. when on), and the range selector switch. I removed the switch, took it apart, cleaned it up, and reinstalled it. It looked like it was in decent shape inside, although it appeared to have had a bit of oil of some sort that had leaked into it. There was a bit of oil on that side of the tranny, around the gear selector and switch, but not enough to actually drip as I don't have any stains on my driveway where I always park. The only thing I haven't checked is the atf fluid level, as I can't seem to find the my wrench that will take off the fill nut. I'll get that figured out tonight.
The tranny hasn't been taken care of like it should, I've had the fluid replaced two or three times over 100k of ownership, but I'm not sure about the filter. Would the need for a filter and fluid change cause it to go into limp mode? Also, it's not throwing any CEL codes either.
Nissan XTerra 2005 transmission RE5R05A. Trouble code is p1757 When I go from park to drive it goes out of gear and puts my car in limp mode. I took it to the dealer and they told me that I have to replace a transmission another place told that it could be brake solenoid or oil filter. In third place they told me it could be the TCM problems.
View 7 RepliesMy Jetta mkiv transmission went into limp mode recently. Took it into shop. They checked it out and they replaced solenoids as well as the TCU. Car still goes into limp mode. It doesn't happen all the time but enough to piss me off. Any thoughts?? Car only has 140000 miles.
View 1 Replies03 manual goes into limp mode with ac on like turbo has no power and wont go past 65. No engine light comes on though. Does engine light have to come on to go into limp mode??
I don't have Vag Com. But i'm familiar with diesels. Maybe something is losing vacuum when a/c comes on because i know the ducts and all that work off vacuum in most cars. Does the ducts for TDi work off vacuum also??? Maybe not enough vacuum going to VNT activator?? I'm clueless with these cars.
New to the jetta (used to own Saabs so not new to issues) OK, 2003 jetta 2.0 CEL is on for the CAM Post sensor. Car is in limp mode. has been for a while before I touched the car. I have replaced the Cam post sensor, I replaced the Crank Post sensor, replaced the coil pack, replaced the water pump and the timing belt. I have searched a lot of the other threads before posting this one. Triple checked the timing (3 people did not just me) I replace all the other stuff because I had codes the water pump and the timing belt just because they were due. i had one last code P0343 so when i replaced the WP and the TB i replaced the sensor. Still in limp mode, still have the code i pulled the plug on the Cam post sensor. then i said to my self this car should NOT start. but it did start and i drove it around a little, shut it down and car started up again so I am at a complete loss.
View 8 RepliesI have a 02 Jetta TDI, I have had the car
For about 8mo, and have been fighting a random limp mode problem the whole time.
I have gone thru and changed the common issues, N75, MAF, actuator on the turbo, and changed all the vacuum lines, fuel filter..... Etc. I'm to the point I want to light the car on fire, and see if the engine light goes off!!! Is there something that I have overlooked.
I currently own a 2001 Jetta 1.8t. It is currently tuned for 15 psi supposedly. I have never seen that number been hit and the highest it will go(only in 4th and 5th gear) is 13-14psi on a good day. And even when it does get there it does not hold the boost what so ever. It will start losing boost almost as soon as it reaches those numbers. Another thing is my MAF is currently unplugged and is making my car throw a code. When MAF is plugged in it cuts out boost and goes into "limp" mode.
Here are some engine mods that may be apart of this issue:
- Front mount intercooler, full intercooler pipe kit
- Oem diverter valve
- N75 j valve
- ACHTUNING tune on 15 psi not sure which stage
- Forged turbo inlet pipe
- 032 motorsports crankcase breather hose conversion
- Ecs tuning
- 2.0t coilpacks and mounting plate
- AWP head
2001 Jetta 1.8T wolfsburg
When I start my car the ASR light is already on and I cannot turn it off by hitting the button. It's just permanently on. Then as I start to drive and step on the throttle and get above 3000rpm the ECP light turns on and my car goes into "limp mode". Then in idle the engine stutters and RPMs go up and down, up and down. I'll turn off the car and the ECP light disappears but comes right back on again after getting above 3000rpm.
Thing is, these issues only appeared immediately after the following:
-Disconnected and reconnected CCM (checking for faulty wiring, battery was connected during this)
-Disconnected battery terminals for 3 minutes and reconnected them (no key in ignition)
Did I cause an issue by disconnecting battery?
I have an automatic (ugh) 2002 Jetta 1.8T that is displaying some fun stuff. My kneejerk reaction is that the ECU is croaking but wanted to run it by some people with more experience/smarts.
Here's the deal. I don't get any codes, ever. Sometimes, when I turn the ignition to on (Before starting) all of my warning lights are dim and will flicker, and the gear indicator at the bottom of the cluster rapidly switches between each gear. If I start the car like this, I can hear the shift lock randomly engaging and disengaging. If I actually try to drive, it'll shift hard into reverse, shift normally into drive, and then drive in limp mode. I only drove this way three times before figuring out the next bit. Each time, either the traction control or air bag warning lights came on and stayed on.
I've noticed that if I turn the ignition to "on" and it's acting up, all I have to do is leave it on for a few seconds, turn the ignition back off, and turn it back on; sometimes it'll take 2-3 tries but it always seems to work. Then the warning lights come on bright and steady, the car starts like normal, and drives great.
So, is it the ECU? Is it demons?
I have a Mk4 1.8t , I left a light on and near killed the battery one night , was parked on a hill so I let it roll start.( I know this is where I went wrong so lets get past it....) It started in what sounds like some type of limp mode, dim dash lights and about 300-400rpm. cruised at about 10mph for say a 1/4 mile before the engine returned to normal rpm and lights returned to proper brightness.. now the car has a problem I cant seem to put my finger on. When it gets to about 3000rpms it bucks and begins to throw multi misfire codes making it hard to even get to 30mph.
It reminds me of how it felt when all the coils started failing but I know it cant be that because its all new , (plugs ,coils,) I have also replaced a few other easy parts such as the n75 and the diversion valve next to it, as well as the fuel pump and filter. One thing I noticed when I leave my n75 unplugged (wide open) it seems to run better making it easier to drive but if I go anywhere past 1/4 throttle it bucks and struggles. I've used the Autel to scan it for other codes but the only thing I get is random multi mis codes and mis codes for each individual cylinder.
I have a 03 GLI 24V VR6 6 speed and im having an issue with the brake light.. ive checked all the fuses and emergency brake sensor and they are all good, the issue is the brake light flashes 3 times then will stay on almost immediately and whenever it does the entire drive of the car changes.. without the light on the car runs fine but when it comes on its like the car goes to a limp mode and is leaning out on fuel.. it wont rev past 4k it falls on its face and basically jerks along until I get where I am going.. I've replaced ABS speed sensors, MAF, and front brakes and axles recently.. before this was an random issue that would come and go but now its almost every time and it makes it undriveable..

View 2 RepliesMy wife has a 2006 santa fe 3.5l limited over the winter it started acting up went into limp mode and would only go 20mph so I went and picked up a TP sensor well it went out of limp mode so I never changed the sensor well last month it started doing it again so I changed it out didn't work!!! comes up with 2 codes sometimes p2110 and p2118 but normally its p2110 2 times.
If I hit the break it kinda bogs down and pulsates.i took it to my mechanic since I couldn't figure it out and with advice from a hyundai mech. He changed APS didn't fix it so we changed throttle body with used of course didn't work I checked wires and didn't fined any open circuits what are the chances that i got a bad APS or TPS...
Have a 2003 F350 srw 4x4, 107,000 miles on it. Driving it last night tow/haul light started flashing, hooked up AE got a P0730 Incorrect gear ratio. Truck seem to do ok, cut it off went back out a little while later and the tow/haul didn't flash.... Only issues I've had is when shifting from P to R, it takes a second or two longer than it should and shifts hard when it does but it doesn't do it every time.
View 1 RepliesA few months ago, my '00 Sentra developed a rough idle but I ignored it because it wasn't too bad, until recently at least. It had been getting progressively worse so I went out and bought some CRC MAF cleaner, which solved the rough idle altogether for about a day. After doing some errands, I started the car but it was now stuck in limp home mode, not matter how much gas I gave it, she wouldn't top 20 MPH and 2.5k revs.
I bought a new MAF, and that made the problem worse: in any drive gears or reverse, when given any gas, the engine would stall and die but when in neutral, I can rev it as high as I want to. I reset the computer and cleaned the new sensor to no avail. After re-installing the old sensor (which was visibly broken, it was missing an entire wire assembly), it will run poorly but will now drive with some quirks, and I don't trust it further than around the block.
My question is: with the new sensor, do I need an ECU reprogram, did I receive a bad sensor, or is there a compound problem? (I've heard with similar issues: bad alternator, bad TPS, bad IAC module, dirty IAC or TPS, clogged fuel filter, bad fuel pump, dirty air filter, among others.)
Wife come home the other day after leaving for work with the truck no going past 20KM to 30KM.. After some investigating it seems to be in Limp - In Mode. There was a Check-Engine light & after further investigation found a Vac hose with a leak, repaired this & test drove. Same issue.... then there was a loud hissing sound from the engine area so I investigate & now found the EGR sensor (DPEF pressure sensor ) had blow a hose & fried the sensor.
New sensor was replace along with 2-hoses cleared the engine light but the truck still will not go more then 20KM or 30KM max.. I checked the EGR valve with vac pump & engine stalls or so the valve is good. I have left the neg cable off the batt to try & clear the Limp-In mode without success. Looking for a way to clear the limp-in mode or do I need to clear it with a scan tool?
