Golf IV / Jetta IV :: 2001 - Computer Failing Or Throttle Sensor?
Jan 21, 2015
2001 1.8T Wolfsburg
Started it this evening and went to the store, on my way there the car was right messed up. No lights, wouldn't go over 500 rpm (no throttle response), eventually was stuck on the side of the road. Reset my throttle back to OEM and everything went back to normal, car hasn't shown any trouble since but it's only been a couple hours. I don't want to end up stranded somewhere so I'm wondering if my computer is possibly failing or should I try replacing the throttle body if it does it again?
Car is not chipped and was OEM throttle before (to my knowledge).

I'm posting as a last ditch effort to try and rescue my 2001 Vw golf here's some quick details about the car then I'll go into the situation.
2001 Golf 1.8t 5speed
Euro customs stage 2 Aftermarket intake and downpipe
Still have front and rear O2 sensor and probably cat. Maybe..
Otherwise stock
201k miles
Okay so pretty much here's the rundown.. I was driving my car to work one day, then all the sudden lost complete throttle response to my car but was about to cruise at about 5-8mph to get to work and avoid towing. What is going on besides the EPC light was on and CEL was on. After work I discovered that the rear O2 sensor was hanging down and frayed.
Apparently from what I was told, that fries your ecu and put the car into a similar mode as mine. I then replaced the ecu with the euro customs ecu, I replaced the throttle pedal, and the throttle body since all I was getting was throttle codes. I am still not able to get rid of either EPC or CEL lights. The codes showing are p0638 and p2101. Yes I have tried to get the throttle body realigned or whatever you call it. However the vag com will not let you realign with the codes still in the computer which have been deleted but come back immediately.
The rear O2 is still unplugged and I still have little to no throttle response.

What are the symptoms of a bad o2 sensor, 2.0.. My son is having some problems with his car hesitating when he gets into the throttle and the only codes we are getting shows bad O2 sensor pre cat.

I have a 2001 vw jetta 2.0 and I was accelerating on the interstate the other day and the car just started bogging down and now the car only accelerates slowly at partial throttle any more and it makes a loud intake noise and bogs down also the car idles bad and even at partial throttle the car struggles to get above 3k rpm, I scan for codes and got MAF, O2 sensor before the cat and camshaft position sensor, I replaced the camshaft position sensor and car still runs like crap, what is the problem??

I made an earlier thread about minor low speed crash and airbag deployment that has sense been fixed.
The engine 2.0 (AZG) will rev to 3000 (3200 sometimes) RPM and stop. This is only if you give it about 20% / 25% throttle. If you give it full throttle it spits and sputters. When I had the airbags installed. The codes were read it and also came up for cam sensor and o2 changed that and now the codes are gone. No CEL and it is exact same issues still. I can't tell if ECU is doing it but it feels like it's not getting enough gas or air since full pedal makes it stall.

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 just had an OBD code pulled on my 2010 Camry and it turns out that my Heated O2 sensor for Bank 1 Sensor 2 is failing. I'd rather do this myself if I can but I can't figure out where this thing is. Is this something I can access myself and swap out? Or does this need to be fixed by a mechanic?

I bought a 2001 golf gls 1.8T (AWW) about a month ago and it was running pretty bad, was throwing some codes, cylinder 1 misfire and some o2 sensor codes, I replaced the coil packs and spark plugs and then cleaned the MAF. It was still running bad ,rough idle and power loss. I figured it had to be some kind of vacuum leak, I replaced the PCV valve, cleaned the intercooler and put on a silicon TIP. Still had some rough idle and power loss, checked for vacuum leaks, using the good ole starter fluid method and found my intake manifold was leaking so I replaced that gasket. STILL rough idle and power loss, now I'm pulling codes for o2 sensor and a misfire in cylinder 3. My question is, should I replace my pre-cat o2 sensor or replace my MAF sensor? Or are there other things that should also be checked/replace.

So my girlfriends's 2001 2.0 Golf (engine code AVH, 153k miles) began throwing codes for misfire on cylinder 4 and for the o2 sensor (post-cat) recently. I went ahead and replaced the spark plugs, wireset, and the coil pack. They were way overdue. The CEL went away for like 30 miles, and then came back. Now it's reading misfire on cylinder 3 and the same thing for the o2 sensor. What else it could be? Search is coming up blank, most people replaced the coil pack and the CEL went away.

2001 jetta 2.0 VW guys a while back I was pulling a code saying that the air temp sensor circuit was low I believe it was P0112 so I replaced the maf with a bwd maf. Said it was for the car. Was fine for a day but now it has a P0102 code and the epc stays on (rough idle) what could be wrong ? Is it because the car hasn't learned the new sensor yet because I've only drove 10km or do I have a faulty sensor. BTW replacing the maf fixed the P0112 code

I drive a 2001 Jetta with the 2.8 v6 with ~125k miles
So for a while my car was giving me a false read on my temperature so I replaced the sensor. I actually followed instructions from a thread on this site. [URL] ....
Now when I go to drive my car, it runs sluggish and misfires if I really give it some gas. CEL is on(however does not return a code when hooked to a computer), and flashes when gassed hard.
I've checked to make sure spark plug wires were reconnected correctly and securely. No leaking has occurred from the temp sensor. shift rod drive unit is reconnected correctly.

My temperature has been randomly dropping, them back to middle, and recently my engine was overheating because I'm guessing the fans didn't turn on, because I'm also guessing, the engine didn't know it was overheating?
Anywho, during my replacement, I made sure to get rid of the pressure, and the car was cold. I tightened the cap again, but when I took the sensor out, all the coolant spewed out.
Now if I understand this correctly, do I have a leak? I figured the leak I had was coming from the temp sensor as it is.
Here's some pictures for those who'd like to see ....

I have searched and have not found any information on replacing the throttle position sensor. My Santa Fe was running normal. I changed my tp sensor and how it limps along. When I loosened the old TPS, not even removed it, I heard a noise inside the TPS. When I replaced it I adjusted the TPS to read between 9 and 10% on my reader. But when I push on the gas pedal with the key on position the percentage doesn't move. Also when I drive it now it limps along and does not accelerate.

Codes P0210 and P0733 for throttle sensor and third gear mismatch came in.
Dealer is going to replace throttle position sensor and said the Hangar Bearing is bad needing replacement.
I was just curious how long those jobs take to do roughly?

Getting code P2125. Read on here to get some electric contact cleaner and see if that works by cleaning the connections.
If I do end up changing out the Throttle Position Sensor, what voltage value do I look for when installing the new one ?

my old lady has a 2001 olds intrigue with the 3.5L in it. Sunday evening we replaced the Throttle Position Sensor and the Coolant Temp Sensor. Monday she was on her way back to Iowa and the tempature gauge spiked up to the Hot area. I looked it over and could not find anything wrong. I sent her on her way and she made it about a mile before it did it again. The car will spike up to the hot area but the motor shows no signs of over heating. I checked the temps with a heat gun while the car is idling and read out Thermostat housing-160, Rad-80, Rad hose-130, and coolant 170. I than ran the car up so it shows on the gauge its hot and than checked again, it than reads Thermostat housing-172, Rad-100, Rad hose-134, and coolant 184. If I am running it at 1500 rpms it will spike up but once i take it up to 2500 rpms it drops back down to normal on the gauge. I am lost for what it could be.

I just posted last week that my check engine light was on and the dealer wanted to replace fuel injectors. But after the fuel throttle was cleaned and oxygen sensor was replaced the check engine light went off. However, yesterday the check engine light came back on. I am talking it back to the dealer, in a couple of days. Where can I go to get to get the error codes read so I have them before I go back to the dealer? Around 128,000 runs fine, around 40 miles per gallon. Last time I had the oil change dealer nothing came up on the 30 point inspection.

2004 VW R32, No engine mods. I did have the vacuum line sealed off for the flapper mod for about 3 months but is is now back to normal.
I've got the MIL, ESP, and EPC lights on and scanning codes as follows:
Code-P0222
Definition:
- Throttle pedal position (TPP) sensor/switch "B"
- Circuit Low
Explanation:
- Open or short circuit condition
Probable Cause:
- Poor Electrical Connection
- Faulty TPP sensor
- Faulty throttle valve control module
I don't know much about the situation but I took it to my friends shop first where we replaced the Throttle body, intake, and MAF. Didn't fix the problem so I took it to my local VW dealership and the tech's exact words were.."the codes coming up as a throttle pedal sensor. Is there perhaps a sensor by the pedal that I could check?

Am getting an EPC light + limp mode + code for accelerator position sensor (implausible signal). I have swapped out the pedal assembly, so it isn't the sensors themselves, and we've checked the wiring to the pedal assembly... I can feel in-car, and I can see via VAG-COM that one of the two sensors is basically toggling between a sensible % reading of pedal position at one moment, and then zero % the next, and of course every time the sensor reads zero, the ECU notes the error and cuts power... but this only happens when the steering wheel is straight or when turning to the right; I can drive around in a leftward circle all day and night without this occurring.
Why? What is there in the steering (either in the column or at the wheels, or basically any place in between) which, if malfunctioning, could affect the accelerator position sensors in one way or another (i.e. either through the normal operation of a safety system, or through a short or other electrical gremlin)?
