vwsgt_0311 0 Posted August 7, 2008 Report Share Posted August 7, 2008 I am new to this forum but i really need help.First of all, i have owned and worked on many VW's for quite some time but this is my first VR. I took it to get inspected and it failed due to CODEs: P1544 Throttle Actuation Potentiometer Signal too High and p0121: Throttle pedal/position sensor A ciricut range performance. I did some research and it turned out to be the TPS and probaly need a new TB.I have checked the ECU and it is an OBD2When i looked under the hood i noticed it had an OBD 1 TB on it. Could it be possible that who ever owned it before me replaced the engine harness with and OBD1 as well as the TB? Can it be a simple fix such as replacing the engine harness again with OBD2 and TB or is there any way i can make something work with what i have?vwmico@gmail.com Link to post Share on other sites
Smuggler 0 Posted August 7, 2008 Report Share Posted August 7, 2008 What year is the car, maybe its had the engine changed with the loom for obd1, or had just the ecu replaced with an obd2 one? Link to post Share on other sites

vwsgt_0311 0 Posted August 7, 2008 Author Report Share Posted August 7, 2008 It is an OBD1 engine and engine harness, it is running of an obd2 computer, By the way the car is a 98 GTI VR6, will it be as easy of changing the engine harness with an obd2 as well as the TB??
