Title: Car Cutting Out High Revs
Post by: Tally on April 11, 2019, 02:21:52 pm

HELP NEEDED.
Any ideas on me mk5 golf gti .
Changed
Coil
Accel pedal
Throttle body
Fault codes

P0222 - Throttle angle sensor

P0123 - throttle position sensor to high

P02122 - accel position sensor to low

P0642 - sensor ref voltage A to low

P0698 - sensor ref voltage to low

It’s ok if I don’t boost it. Once I kick over 3000 revs especially in 3rd / 4thgear it either goes into limp mode, EPC-Enginemanagment and traction control lights come on and I lose power but still drive it OR completely packs in EPC and traction light but no revs undrivable. All I do is disconnect battery then it’s fine 🤔🤔

Please can any1 Advise. I unplugged the MAP Sensor and it was ok for a while, Ran better but its started cutting out again.. Im at my wits end :bang:

Could be throttle body needs changing.  Quite a common issue on these

He's changed the pedal and throttle body apparently.

Did you fit new or used parts?  Was the replacement pedal like for like?  I.e. GTI.    For example, a diesel or R32 pedal might not work correctly with a GTI ECU.

I would also check your wiring harness that runs under the vacuum pump and connects to the throttle body.  It's a known problem - https://forums.vwvortex.com/showthread.php?5293518-MKV-GTI-Throttle-body-wiring-harness-repair

It's an EA888 engine in that link as America got that in their 2008+ GTIs, but the same applies to EA113s.
