Hello and thanks for reading my post. I recently picked up a 2006 VW Jetta 1.9 TDI 5 speed manual. The EGR cooler was leaking so I deleted the EGR valve, ASV, and EGR cooler, then installed a race pipe. I have yet to tune it since I wanted to see how it did on fuel as a baseline (37 mpg for those interested). I've put 750 miles on it and the check engine light was of course on for the EGR.
All of a sudden, the accelerator pedal stopped responding yesterday while driving on the highway and the glow plug light started flashing, which I have found means there is an engine management fault. After getting ready to pull over and call a tow truck, it started working again, but the car was in limp mode.
I pulled the codes with by OBD2 scanner and got:
P0122: TPS/Pedal Position Sensor A Circuit Low Input
P0642: Sensor A Reference Voltage Circuit Low
P0101: MAF or VAF A CKT Range/Perf
P2413: EGR System Performance
Freeze Frame Data:
DTC that caused freeze frame: P2413
Throttle Position: 94.5%
Engine RPM: 0 RPM
Load Value: 0.0%
Air Flow Rate: 0.00 GR/sec
MAP sensor: 99 KPA
Coolant Temp: 77 F
Intake Air Temp: 71 F
Vehicle Speed: 0 MPH
I know a VAG-COM is the best way to get readings, but this is all I have at the moment. From my research, I've seen people say that this can be caused by a faulty accelerator pedal sensor, ASV, or even the ECU. Many threads that are started do not mention if the issue was solved and how. Any information on diagnosing this issue would be much appreciated. I saw mention of testing the pins on the pedal sensor, but no information on which pins and values. Thank you in advance for any and all advice.
