We are having an intermittent issue with car starting up and immediately throwing a CEL, red triangle and going into limp mode. Shutting off the car and restarting it sometimes resolves the issue. I'd love to be able to pull the logs from the car to see what is causing this issue.
View 11 RepliesI recently bought a h&s tuner and installed a dpf delete kit. Everything works great when the truck is not plugged in to the tuner although when I do plug it in, the truck keeps throwing a communications code and goes into a limp mode until I delete the code. I believe it was p0073 but i maye be mistaken. Regardless it has to do with communicating through the obd2 port. I sent the tuner in to get checked out and it turns out its something to do with the truck. I've checked all the fuses and tried to check for broken wires. Where to look next?
View 4 RepliesI have a 2005 Prius. After driving home from a 95K routine maintenance inspection, the car (with the display indicating 50% in the gas tank) went to limp mode and then stopped entirely and had to be towed back to the dealer. The codes pulled were
P0A0F (Engine failed to start)
P3000 (Battery control system)
B2799 (Immobilizer Malfunction)
P3190 (Poor engine power).
The techs concluded that the car was simply out of gas and the display incorrectly showed I still had gas in the tank due to a broken sender in the tank. They also said they added 1 1/2 gallons, and the car ran fine again.
However, I keep meticulous records of when I get gas, and according to my numbers I had at least 5 gallons left in the tank. Sure enough, the tech topped the tank up, which only took 4 gallons, so clearly my tank was not empty when this happened.
I have a 2007 Prius and it will be my first car once I get my license. It has a bad traction control computer and is stuck in limp mode. I have a neighbor who has worked on these and will show me how to replace it. Right now I have two questions. I keep coming up with how to disable it not the actual part.
View 1 RepliesMy wife and I are driving our 2005 Prius with 130k miles and have experienced some weirdness with the car while driving. We've got the master warning light (red triangle w/ !), and another yellow (!) warning light, plus the center display shows a red car with an !. I've gathered that it means something possibly with the brake controller, so when I parked I put the e-brake on.
The car was driving fine with these lights on (we were in the middle of Canadian highways and couldn't stop anywhere) except that cruise control would not work.
Eventually, it actually went into limp mode, where we would floor the pedal and the car would barely accelerate. Pulled over, turned it off for a few minutes, then back on and it drove fine, warning lights still on.
I just replaced the driver's front wheel hub, and I can hear the passenger front going bad, so I'm suspicious that this may be related. Just replaced the 12v within the last few months with an Optima.
I messed up a couple weeks ago and left the car battery running while waiting for someone. I noticed after doing that, that whenever i had the car is standby mode the red triangle would come up and stay there. Today i got into my car and when i tried turning on the car it died and only had a check engine light come on. I read online that it was the battery so i got the car jump started.
We did this with one of those jump starter boxes (not another car) and now the car is running fine. I read that jump starting a prius could cause damage to it and checked the battery levels. When i pushed the power button once the 12v level was at 12.4. When i pressed it twice the level was at 12.1 and when the car is on the level is at 13.9. My 2004 prius is now at 161k miles. Am I fine using the car as it is? or should i change the 12v, or check if the HV is alright?
I have a 2006 Charger R/T. My car used to not start (even thought the battery, starter, and alternator was good). I had it fixed, and the problem seemed to be electrical. However after that, it would always start, but would go into "limp mode". I let it sit for two days, and the limp mode disappeared. However, it will only start on occasion. It won't start after about 30 mins after use. It won't start for a few hours. All electrics work fine, it just won't even attempt to crank. Try to start it later, it will work fine. Even though the check engine light was NOT on, I was able to pull three codes out of it: U0100, U0103, P0700. I did have to replace the notorious "pink thingy", but everything (should be) connected fine.
View 1 RepliesHappened once or twice where I tried to back up a hill and the car went into limp mode. Neither the dealer nor my mechanic could replicate it.
View 5 RepliesMy gen I Prius started having issues. Every time I drive about 30 miles the triangle and check engine light come on with a ding and also my dash lights immediately dim. I just replaced the 12 v battery. Still no fix.
I also switched the fuel pump relay with the horn relay which seemed to work the dash light dimming problem (oddly enough). So I'm not sure what it could be.
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.
Got a 2006 GX throwing a P2445 code and car goes into limp mode. Is this the Air Injection Pump? Where it's located?
View 7 RepliesI have an issue with my 2004 2.7 Santa Fe. I keep getting fault codes P0335 and P1372, the engine then goes into limp mode and is very hard to start.
So far I have replaced the crankshaft position sensor, the MAF sensor, the spark plugs, new ignition coils and leads.
I have traced the wiring and found no shorts, the only thing which does not match the service manual is that I get 5v on the CKPS sensor wire when the ignition is on, it said it should be 0V.
The car can sometimes run for 50+miles with no issues - then stalls with codes P0335 and P1372. I have a feeling its worse when the aircon is on but cant be 100% certain/
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?
My wife started up my 2005 GX470 this morning to go to work and drove maybe a half mile before she noticed a problem. So she turned around and drove it back home in limp mode. She put it in park and got out.
Most of the Warning Lights are on ( VSC OFF, VSC TRAC, Anti Skid, Check Engine etc). I tried moving the shift lever but there was some resistance and some grinding noises. And it now seems to be stuck in neutral.
How to diagnose this myself? We only drive this vehicle in the winter, and it was fine the last time we used it.
I am one of the few that has ADC on my 2004 V10.
Occasionally, 3 times now. I press the ON button and the cruise control does not initialize properly. After a while it will say "Temporarily unavailable" . The problem is that then there is no power any more.
I stop on the hard shoulder of the motorway, engine off, engine on and all is reset, ADC works ok and full power is restored.
I was once the proud owner of a 2006 Prius with 106,716 miles on it. Never missed a regularly scheduled service. Now, I am no longer proud, but just another owner of a Prius with a failed transaxle.
Last week, I parked my car on my way to work and, while the car was idling in park, the Triangle of Death (red with exlamation mark within) came up on the dashboard. The car went into limp mode -- it was unable to shift into drive or reverse -- so I had it towed to Darcars in Silver Spring, MD. They thought the original 12v battery was dead, so they replaced it.
P0AA6 -- 526 and 613 codes 600 miles after Transaxle Fluid Replacement...
I was driving home. Problems started after pulling away from a 4-way stop. Truck started lunging almost like I was running out of fuel. Then I got a "Transmission Malfunction" in the in dash display. Followed by limp mode. I checked the Faults when I got home. I have the following:
P0720 - Powertrain - Output speed sensor Circuit
P2106 - Powertrain - Throttle Actuator Control System - Forced Limited Power (From what I understand this is associated with limp mode. Not a root of the problem)
P0713 - Powertrain - Transmission Fluid Temp Sensor Circuit High Input
P0722 - Powertrain - Output Speed Sensor Circuit No Signal
The vehicle has around 192,000 mi. Replaced cam phasers in upper engine roughly 1000 miles ago and replaced all the bearings in the rear differential roughly 100 mi ago. I haven't messed with anything on the transmission. Checked fluid level and color of transmission fluid.
Just fully rebuilt transmissin 4r75 replaced all planet gears clutches etc. Now with it all back together the speedo does not work on truck goes into limp mode. I replaced the vss sensor an no luck
View 8 Replies2004 Explorer Eddie Bauer . Bought it like this and trying to figure why. Code is P0740 and P0743. It will go about a mile then go into Limp Mode with the Orange Wrench symbol and will die. If I pull over and restart it will go another mile before doing it again. Any Tips? Trans is 5R55S....
View 2 RepliesOk just bought this truck ran fine. Put a sct tuner on that the truck came with and some how got the egr turned on. It had a egr delete so it was smoking and finally found it out that it had turned on but fixed it. Now we have another problem, it will start up and run fine and about 45 seconds it will start running rough and go into a limp mode. It will run rough and starts to die slowly and when it starts to die there is no throttle at all.
View 4 RepliesI have a 2008 F350 with a 6.4 Powerstroke diesel engine that just experienced total engine failure. It has around 65K miles.
There is a heavy burn star pattern on all 8 pistons, a few pistons are cracked, a few cylinder walls are scored, glow plugs are melted, both heads are cracked with multiple stress fractures in each head.
About 1 month previously, the transmission would not work in tow mode and caused the engine to go into limp home mode. The dealership just replaced the entire tranny as a warranty item. About 1 week before the engine failure, I put in a 5.25 oz bottle of Lucas injector cleaner with a full tank of gas.
The Ford dealership is saying that the star pattern on all 8 pistons is due to high pressure fuel overspray and is evidence that I had a tuner on this engine and that the warranty is invalid. I did not have a tuner. What might have caused this engine failure?
Also, they only ripped down the top half of the motor, not the bottom half. I heard this might have been caused by a cracked crank shaft, but Ford refuses to investigate this possibility.
