Golf IV / Jetta IV :: Check Engine Light Came On / P0135 Code For Sensor Heater Circuit
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. What is wrong and how I can fix this?

My engine is in trouble. A few weeks ago, my check engine light came on. The diagnostics revealed that my Mass Airflow Sensor was done for. I replaced it, and everything was working fine for a week. Then a couple of days ago, my Electronic Power Control (EPC) light came on. The car is really dragging. It have to gun it to make it go above 60 MPH. It's become scary to drive on highways. Are the two issues potentially connected?

2000 Jetta 2.0. 140k miles. Cranked, but would not fire. Sprayed starter fluid... nothing. No spark. Checked fuel pump and fuel pump relay, all is well. I let it sit over night. I tried starting it, ran for 4 to 5 seconds shut off. Disconnected MAF sensor, it ran. Put in a new MAF sensor, back to cranking no fire. Let it sit over night, started up again. Tried to drive, stalled. Unpliged MAF sensor, now its running. Drove around parking lot. Afraid to take it out, don't want to be stranded.
View 1 RepliesGolf IV / Jetta IV :: Oil Sensor Light Goes Off Intermittently
My oil sensor light goes off under specific conditions, and it's consistent and 100% repeatable.
It's an MK4 Golf GTI 5-sp Manual, and whenever I'm slowing down and the engine is under 2000 revs, the sensor light goes off. This includes stopping, slowing going down or up hills, and really anytime the engine is lower than 2000 revs.
I've replaced the oil sensor, no dice. I don't know what else the issue might be?

.About a week ago NC got some really bad rain and in about 5 minutes the roads were under water. I had to end up driving through about a foot of water to get home, then parked the car. On my way home from work the next morning my car barely made it home, would cut out over 2k rpms and die if i didn't push the clutch in.
I sprayed some MAF cleaner on the sensor and tried that, it now will not idle when slowing down and will shut off every-time while rolling. (Also, while it is running it idles HORRIBLY and doesn't seem like it wants to pull boost efficiently)
I unplugged the maf and it does run a little better but when i pull the full 21lbs of boost then let off of the gas it dies.
Also i scanned the CEL and it says something about the MAF, i cleared it but the TC light never went off. and the CEL came back on in minutes.
Golf IV / Jetta IV :: Air Intake Temperature Sensor Missing?
Looking at my circle track car when they told me my air intake temperature sensor was missing this is a picture online I found: [URL] ....
The hole is filled with a bolt and some epoxy. I don't see where the cable is for it. What will this do to my car? It is a track only car.
Golf IV / Jetta IV :: Won't Start - Bad Crankshaft Position Sensor?
My car doesn't start right now and a shop diagnosed it as an ecu, but I'm starting to think that is not the case. The tach doesn't move when I try to start it and pushing the gas doesn't change it, so I'm thinking it is the crankshaft position sensor. Unfortunately, down at school, I don't have access to a jack, so I was wondering if there is any way to get to the cpa without a jack? I'd rather not have it towed to another shop.
Also, my coil pack has a huge crack in it. Could that be causing my problem? And my sai has some really frayed wires and I'd rather not replace it if I don't have to because these repairs are really adding up, but could that be causing problems too? it's not causing gas mileage issues and I live in an emissions-free county, so simply not allowing me to pass emissions isn't a problem.
Golf IV / Jetta IV :: How To Replace Vehicle Speed Sensor (VSS)
2002 Jetta 2.0L...
The Haynes Manual tells you to lift the car up and un-mount the engine mount on the drivers side of the transaxil to get access to the VSS underneath the vehicle, but you can do it from the top of the engine!
1. Take out your Air filter box for easier access
2. My VSS was covered by a metallic heat pouch with snaps. (not mentioned in Haynes Manual)
3. I got Needle nose pliers to wedge in the small area to unscrew the bottom half of the VSS. It is a small area to get your hand in, but with the needle pliers was actually pretty easy.
4. Then get something small enough to release the clip for the top plug. I used my screwdriver.
5. Screw in your new VSS and plug the top cable back, then put your air filter back in place.
If you look at the pictures I took, you can see the VSS and the silver pouch I mentioned. I had a lot of trouble finding the location of the VSS with no real good pictures or explanations online. Note these pictures were taken from the drivers side, which the empty space is where the air filter was and on the right you can see the battery.
Golf IV / Jetta IV :: CEL On For CAM Post Sensor / Car Is In Limp Mode
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 RepliesGolf IV / Jetta IV :: CEL Code For Bad Coolant Temp Sensor?
So my check engine light came on in my 04 jetta sw, and when I had the car read, it gave me a code that tracked down to be a bad coolant temp sensor. I bought the replacement part from my local VW dealership, installed it and the check engine light went away. Now about 2 weeks late it came back on, and I am getting a reading of "Coolant temp sensor high voltage". So it goes from needing replaced, then the replacement is running high voltage?

Monday get CEL with codes p0722 and p0322. Car is in limp mode during these codes. Yesterday I change g68 sensor. Cleared codes, rough start but was sitting most of the week. Drove around fine, no limp mode, shifted fine. Started up a few times immediately after. Hours go by I go to leave and it won't turn over though it sounds its wants to. No clue why this is happening or what changing the sensor could have done. This is a 01 GLS 2.0 auto. Not sure where to from here especially since it drove so well afterwards.

I replaced the knock sensor because I was getting the p0327 for the front knock sensor. Drove it again and still sputtering and CEL came back. What are other causes of this? N75 solenoid? Low fuel pressure?? It has a spectre air filter kit on it. Didn't know if this would do it. I cleaned maf. Just put new plugs in it too.
