Are my Throttle Position sensors voltage 1 and 2 reading backwards? I was told by another member that my TPS1 should read roughly 4V at 0% throttle and below 1V at 100% throttle and opposite for TPS2 roughly 1V at 0% throttle and 4V at 100% throttle.
Mine are reading completely opposite....TPS1 - 0% throttle 1.33V and 100% throttle 4.4V
TPS2 - 0% throttle 3.76V and 100% throttle .53V
It is a 2002 corvette, oem GM MAF, PCM, TAC module with a LS3 gen4 engine with GM LS2 90mm silver blade throttle body. The car seems to run fine but was going into Reduced Power Mode after some hot laps. Can I fix this?
I attached a pic at 0% throttle and 2nd at 100% throttle.
