BMW E9x S6 PNP Tps Issues
Posted: Thu Jan 13, 2022 8:13 pm
Hi,
Im currently having issues with TPS inputs specifically 1A and 2A Inputs pulling to 5v
The vehicle came in running but would idle very high on initial start and now wont start at all.
I have checked all 0v and 5v inputs aswell as the physical output voltage on both 2a and 1a and 2b and 1b output the expected voltages but the ecu input still stays high on Inputs Slave AN27 and AN28
I have tried another tps sensor to see if this changed one of the inputs but no change.
From the wiring diagrams Ive found it looks as if the problem inputs are routed to another set of modules and then transmitted to the ecu ? So potentially another module is causing the issue. Can someone more familiar with this setup please enlighten me and give me a quick run down on the system and how to diagnose further.
Does anyone have the pinout for this PNP ecu 2008 BMW M3 S65 V8 Engine
I can supply the tune calibration but the car was working previous to the high idle and tps issues.
Thanks
