Just installed a short Ram intake on my 2000 Vw Jetta 1.8t. Had the Intake for about 250 miles and now the check engine light came on. Just pulled the code p0411 secondary air injection system incorrect flow detected. Is this just cause there is more air going through the MAF sensor?
View 11 Replies98 Taurus, 6cyl, 3.0L OHV, 184K miles. Check engine light is on and code reads "P0411 - secondary air injection system - incorrect flow". This is my son's hand me down car and has a rather large exhaust leak that I plan on fixing. Could this code be related ?? I found out that the CEL has been on for quite sometime now and the car is due for emissions testing (state inspection) in October.
View 3 RepliesAlright so my car is popping up 4 codes.
P0411 - Secondary Air Injection System Incorrect Flow Detected
P0300 - Random/Multiple Cylinder Misfire Detected
P0302 - Cylinder 2 Misfire Detected
P0303 - Cylinder 3 Misfire Detected
Vehicle: 1999.5 VW Jetta MK4 2.0L GLS (AEG)
The P0411 code I have had for a while now and I been lacking to fix it. I pretty sure I can get this fixed but it doesn't cause problems so I haven't paid to much attention to it. Anyways, the other day I noticed a puddle of coolant under my car so after checking it out, the water pump was leaking so I bought a new one and replaced the old one. However, during the replacement process I had to remove the timing belt and I accidentally turned the top pulley about 1 notch and didn't notice at the time. After putting everything back on, I turned my car on and the engine sound a bit weak so I ran for about 10 minutes around a couple blocks.
I instantly noticed that the car had no power and it took me a long time to speed up. When I got back, I plugged in my scanner and I only had the same P0411 code and nothing else. After carefully reviewing the camera I had recording during the water pump replacement, I notice I had turned the top pulley a bit so I went ahead and removed the timing belt, readjusted it, and it worked! I was excited that the car was working fine again. Soon after, I headed out to take a drive and noticed after 60MPH the car didn't have much power. The car still accelerates after 60MPH, but extremely slow. As soon as I arrived back home, I plugged in my scanner and that is where I seen the 4 codes. Now my question is what could have caused this? Could I have damaged something when I ran my car with the incorrect timing?
Things I have done so far:
-I checked to see if I left anything unplugged.
-I checked for any vacuum leaks
-I checked my oxygen sensors so see if I was running rich/lean
Things I will do after work today:
-Check the spark plugs
-Check spark plug cable for damage
MK4 GTi - My check engine light came on a few days ago and when I checked it, it pulled code P0420.
Just this morning, the check engine light went away.
Is this a common issue? Or should I go get it checked just in case?
I have a 2005 Jetta 1.8t and the thing will not start! The battery is fine, and has been recharged 100%. The fuel pump is pumping. It cranks all day, but just won't start. The only error code i'm getting is a P0411 which I understand is a leak in the vacuum system somewhere.
View 5 RepliesI have a 2000 jetta 1.8t. Check engine light recently came on and the code is a PO1128. I replaced the maf sensor and that did nothing but make the car run worse. I've check for vacuum leaks and found a busted line at the egr valve, fixed the line, reset the code only to have the check engine light come back on with the same code. I am at a loss now.
View 3 RepliesI've been having an issue with my car and the check engine light is on.
The code reads : P0030
Heated oxygen sensor - bank 1 sensor 1
heater control circuit
2001 VW GTI VR6 ....
Whenever P0411 triggers for me, it is very late into driving (i.e. like 30 minutes into the freeway type of situation) where the engine has already hit optimal temperature. I've gone 1000 miles after reset before it triggers. Sometimes 200 or so miles, but it never triggers quickly after a reset. I'm unsure if it matters, but the VR6 does have a cold air intake (and I do have the breather hose connected & maf correctly connected). I'm pointing it out because p0411 became an issue about 500 miles after I had installed the cold air intake.
View 6 RepliesI have a 2005 1.8 TJetta GLI owned for about 2 months now. Gas cap warning pops up then goes away when I turn off the car then check engine light comes on. I've change the gas cap to new oem one changed the purge valve [URL] .... After a couple of weeks same issues again brought it to my mechanic he ran a leak detector and told me that there are Evap leaks. I read somewhere that I might need a need charcoal canister and a fuel tank.
View 12 RepliesBought a Mk4 1.8T gti last year had only about 75,000 on it and drove it for about 10,000 miles. The check engine light went on about 2 months ago and the code read 3rd gear incorrect ratio. It still rode fine until about a week ago when it started slipping. Brought it to the local transmission guys in my town and got a quote at about $3,000-$3,500 to have the transmission rebuilt. The transmission is a tiptronic automatic 6-speed.
View 1 RepliesI have a 2002 Jetta 1.8t. My check engine light came on and it gave me the code P0135 sensor heater circuit. Bank 1 Sensor 1. We bought a new 02 sensor and replaced it. We definitely bought the right one too. Cleared the codes. After a little driving the CEL came back on with the same code P0135. What is wrong and how I can fix this?
View 6 RepliesI got 2001 vw jetta 2.0.. I keep getting check engine light,,when i scan it keep saying P0411 Secondary Air Injection System Incorrect Flow Detected. i replaced new smog air pump, and new egr valve and today i was driving car and i got check engine light, its still same code.
View 4 Replies2004 VR6 24v ... I had another thread about my son's car stalling after driving about 20 miles and then running good again after letting it sit for a couple of hours. Anyway I changed the Crank Position Sensor and I have been driving it work and back the last couple of days so I am starting to relax that the CPS fixed that problem. Won't be positively sure for a while as the problem took a while to occur. So far so good.
While coming to work today the car picked up the P0411 code, secondary air injection system incorrect flow. When I changed the CPS sensor i unbolted a module underneath the car by the oil filter to get better access to the CPS. I did not remove it, just unbolted it so I could push it out of the way about and inch.
After putting it all back together and driving it for several trips with no stalling this P0411 comes on. Is that module I moved the Secondary Air Pump and could I have disturbed something. I will check it when I get home. How critical is that code. I read where it works to warm a cold engine. What effect would there be driving with that code?
I have a 2000 VW Jetta 2.0l AEG engine with 190,000 miles and check engine code P0303 for the 2nd time in 3 months. I had this same code 3 months and 3000 miles ago and found the spark plug #3 to be fouled up. All other plugs and wires seemed to be okay so I replaced plug #3 and the problem went away. I suppose after I take off the upper intake manifold I am going to find the same plug #3 to be fouled up again. The engine is a typical AEG that I have to add 1 quart of oil every 1000 miles as it has been burning the same amount of oil since I acquired the car at 135,000 miles. I have read that the wrong piston rings were installed from the factory on a large number of these engines and VW says that if less than 1 quart of oil is burned after 7500 miles it is normal. I really don't feel like spending 2 hours every 3000 miles to replace plug #3 ? It might be time to part ways with my 2nd VW. As a side note, this car has been averaging 35.5 mpg over the last 55,000 miles that includes 50% city/ 50% highway driving. I coast to red lights and don't accelerate quickly with the 5 speed manual transmission to achieve hybrid like fuel efficiency.
View 1 RepliesI just got a 2001 VW Jetta. I got it with the Check Engine light on. Went to my local AutoZone to get a OBDII reading, got codes P0343 & P0321. P0343 Camshaft Position Sensor A Circuit High Input B1. P0321 Ignition/Distributer Engine Speed Input Circuit Range/Performance. So for P0343 I got the Camshaft Position Sensor for $70 and for P0321 got Crankshaft or Speed Position Sensor for $110 ( FYI, Crankshaft Position Sensor & Speed Sensor are the same ). Paid $160 to get both sensors replaced. I know both sensors are easy to replace but it was easier to pay..
View 3 RepliesI have a 2003 VW Jetta TDI and the check engine light has been staying on solid (not flashing) for a couple of months. I took it to my local dealer who tested the computer and said that it was the thermostat and a related sensor. That answer didn't seem to make sense, and unfortunately I didn?t get the code from the dealer at the time. I did though have the code read recently at another shop and it said: "Code P0674 which is #4 glow plug circuit - Q13 - electrical fault sporadic." What this means?
View 6 Repliesthis is the engine code we got when we checked it out
it also says air injection problem...
what's wrong here?
i assume its something with the vaccum lines?
So for the past few weeks my check engine light has been on. I have a mechanic friend that scanned the computer and says i have a running lean code.... says it could be anything. So i have been driving the car since and now the epc light and drive train lights are coming on... car revs up and down and sounds like is going to die... got the car scanned and says something about the throttle position sensor... before all the lights started coming on i got my fuel pump replaced..... could a faulty fuel pump be the cause? I had my mechanic, clean the throttle body and it ran good for a few days... now the problem is back... I have a 2004 1.8 gti. Do i have to replace the throttle position sensor? Fuel pump again? New throttle body again? I read somewhere on here that a guy replaced some wires near the ECM and the problem went away...
View 7 RepliesSo I get back from being stationed in Korea for the past 2 years. I get my car out of storage and the check engine light is on. I scan it and get P0601. I do some searching on the Tex and see that it's the ecu. I'm tuned on APR. the question is can I take it to a local APR dealer here in Houston and get the ecu looked at?
View 6 RepliesI'm new to the VW world and just bought a 2002 Jetta 1.6SR about two weeks ago. I just realized that when I turn the ignition on before cranking, all the lights come up except the CEL and traction control light. There are no codes stored when we checked it with a scanner. I took apart the cluster today to check if someone had taped in front of the LED but there was nothing, and the LED was intact, it just won't light up! I put everything back together and when I turned the ignition on.
I realized that the traction control light came on for the first time but still nothing for the CEL. I turned ignition off and on again, this time both the traction control and CEL didn't come on. Whenever I unplug the cluster and install it again, the traction control light will come on once, then if I turn the ignition off then on again, it will stop working. I even removed the MAF sensor to test the CEL but it never came on! All the fuses are intact as well... So my question is, is this a faulty cluster, LED, or is something wrong with my ECU?
Was driving today, at a speed one could call "briskly", and the check engine light came on. The code is P0413...
