My 20th is throwing up P0237. It runs fine and everything but this code wont go away. I have tried erasing with no success. I am assuming the MAP sensor is done for?
View 1 RepliesP0237 code. The truck is a 2003 f250 with an edge evo . The truck will run great then throws this code and won't build boost of over 11 psi. Now it even drops it right off to 0. I replaced the map sensor a month ago and doesn't seem to have fixed anything.
View 2 RepliesThe truck was running great besides a little black smoke on WOT and a little jerk while towing. No codes at all. I pulled the EGR valve and got it all cleaned up and reinstalled. I also had time to pull the MAP hose and clean it. I pulled the nipple out of the intake and cleaned it also. I didn't unplug the sensor, just cleaned the hose. Now I am getting an engine light, the MAP gauge reads 2.9, and my turbo gauge is at 22.4 at idle. The truck isn't running right. What should I try first? I don't see what I could have done wrong but this is a pain.
View 11 RepliesI picked up a 03 Jetta TDI about a month ago to use as a daily driver so I could park my Jeep. This is my first diesel so still getting used to some of the quirks and what is normal and what is not.
First problem is a CEL with the code P0401 - Exhaust gas recirculation flow insufficient detected. Now there seems to be a lot of information online about this and how to fix it and everything has something different to say. I live in a cold climate, its already -2 and going to get to -20 - -30 at some points so I'm not looking to to a EGR delete as my understanding is that it takes longer to heat up?
Next, being my first diesel, I'm used to turning heat on and driving for a minute and having heat. Not so much in the Jetta. It can idle for 20 minutes before I head out the door and its throwing warm air but the engine temp is a dead 0. Not until I get on the highway and drive for another 15 min do I actually start getting close to operating temp. Being its only about 0 celsius at the moment...
Other trouble spot is the steering, considering this thing weights next to nothing and has tiny wheels, it is about 4x harder to turn the wheel then it is in the Jeep on 35's. I also seem to get this shrieking/whining from the engine bay about 5-10% of the time when moving the steering wheel and the vehicle is under 5 km/h.
just bought an mk4 1.8 jetta and so I love it, however I'm having a couple issues. I've got a cel for code p0010 something about the camshaft position sensor. I changed the sensor with a new one and the problem is still there. I've got pretty much full power but no turbo spool and my boost gauge tops out at 5-6 psi.
View 5 RepliesYesterday I went to star my 2.0 Jetta and it instantly starting sputtering at idle. After maybe a minute of sputtering the car died. Tried restarting it and it would instantly die after starting. Car threw code P0300: Random Misfire.
As of today the car now runs again with no problems. No codes. I didn't touch a thing and it seems to have resolved itself.
The entire engine bay was wet from condensation due to temperature change. Is there any way this could've contributed to the misfiring? I'm thinking the spark plug wires might have gotten wet and that was causing the misfire.
I am plagued with p0170. Since it started getting the code I have Cleaned maf sensor that was on car (didn't work).
Replaced maf sensor with cheap generic replacement (didn't work).
Thinking it was just a cheap maf I bought a not cheap oem one (didn't work )
Replaced front o2 sensor (didn't work)
Tested intake track for leaks. (No leaks ) boost gauge also reads 25 in hg which also means no major leaks from what I read Tested fuel pressure, and it was perfect.
Changed spark plugs to nkg coppers gapped at .28 (I have a stage 2 ecu but am currently using stock one until issues resolved )
Only think I have not replaced are the spark plug coils and the map sensor.
I also plan on getting a after market wideband o2 sensor so I can see what's going on.
It also seems to pop up when I cruise around 30-40mph. I have taken the car for long drives after clearing codes on high ways amd high speed roads going 45+ and the code won't pop then. Only seems to at lower speeds .
I've recently had some problems with my 2000 Jetta VR6, so in the past couple months I've replaced the alternator and the coolant flange/thermostat housing. I bring this up because right after i finished fixing the coolant leak, i got a check engine light. I had screwed up, though, and switched 2 of the spark plugs when i was putting things back together and I assumed that was what caused the CEL to turn on. I put the spark plugs back in the right place after a minute or 2 of confusion... but the light has stayed on for about the past month. Got it to turn off by unplugging the battery for a bit, but it came back on after a couple minutes at idle. Took it to Autozone... and the P1116 code that pops up says "O2 sensor heater circuit open bank1 sensor 1." I feel like it was probably something that I have done to cause this problem, not actually just a part I need to replace based on the timing of the CEL.
View 1 RepliesMy check engine light went on, and when I scanned my car it gave me the code P1424. I don't know what seems to be the problem?
View 2 RepliesP1128. Have had the code over and over!! No vacuum leaks and I've been through 2 MAFs. I've cleaned the throttle body, changed intake manifold gasket, changed plugs and wires, and put a new air filter in.
The code comes back every few months or so and the car becomes undriveable. Last changed my MAF back in December and the code is back already. What am I missing?
I 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.
View 1 RepliesSo finally got past the smog cert issue and a bad map sensor in the intercooler. However, during the smog test, I was informed I am getting low air pressure in the intake! What causes this? A bad MAF? a leak? I have replaced the EGR, and all rubber that connects hard pipes. The only piece not changed out during the rebuild is the plastic flex line from the airfilter box to the turbo intake.
View 2 RepliesI have a 2005 Jetta 2.0 BEV GLS. I got a code P0302 for misfire on cylinder 2. I am pretty sure it's the Ignition coil. I live in Canada and my autoparts store only has BWD brand. I have read this is a crappy brand.
View 1 Replies2000 Jetta GL 2.0 AEG. I am receiving the P0304 which I have identified as Cylinder misfire #4. I read on some previous posts that I cannot be the distributor because if it was I would be receiving misfires on two cylinders. The spark plugs are OEM NGK and have been replaced recently.
View 2 RepliesWhen checking my check engine light , I got P0021 a cam timing error, but my mk4 Gti runs perfectly ??
View 4 RepliesWhen I'm driving, the Jetta will sometimes not shift from 3rd to 4th gear, so I just turn of the car a start it and it seems to work, but eventually does it again. Once it is in 3rd gear it does not downshift and stays in 3rd even when stopped. The trouble code is P0785 which is the shift/timing solenoid. Not sure if I need to get a new part or which solenoid to get. Also I cannot figure out where this solenoid is actually located or what it looks like.
View 1 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
I recently changed my spark plugs + coil packs in my 01 1.8T because it read a couple cylinder misfire codes. Drove it for a few days out of curiosity plugged the code reader in again and it's still reading misfire codes. What could the issue be still?
View 6 RepliesMy car has been throwing a code P2178
P2187 System Too Lean at Idle (Bank 1) DTC.
Checked the intake, checked maf, checked injectors.
Today after leaving show n go. Stopped at a gas station (never turned off the car) leaving the gas station the car was loosing power, I thought I was in 3rd instead of first. No, I was in 1st. Driving and car was sputtering and wasn't getting any power. After a few blocks it sounded like its gonna shut off. Pulled over to the side. Car died, doesn't wanna start again. Got spark, got fuel to the injectors, discoed the sensor to maf, still cranks but doesn't start. Got it towed to NY from NJ. Still no start. Few people said crankshaft sensor, starter, clogged cat or fuel filter. Car isn't throwing any codes now (probably cuz the motor didn't start) any clues on what it can be?
I keep having the P0102 (MAF Circuit Low) code come up. I've replaced the MAF twice already. I also have the P0113 (Intake Air Temp Sensor) which has been replaced as well. Could the breather hose coming off the Intake Air Duct leading to the oil cooler cause this.

The car sat in a garage for 9 days. It had no problems before. Now I have a p0441 code that comes back after being cleared, and an intermittent gas cap light. Is there a typical problem that causes this?
