DTC P0122 Throttle Position (TP) Sensor Circuit Low Voltage
DTC P1122 Throttle Position (TP) Sensor Circuit Intermittent Low Voltage
Car is Regal GS w/gen V N*
I put tog headers on the car, put all back together with both o2 sensors and now the car starts, runs 3-4 seconds and dies regardless of RPM. The security light does not come on but it was throwing the 1216(?? theft deterrent fuel shut off code) but at least no code from that anymore.
So far I've tried-
-Fuel Resistor Bypass
-Replace TPS w/spare I've checked ohm resistance on the TPS and its ranging 1-5 in steady increments when I move it, also tried replacing with a TPS from another N* I have sitting around and it threw the same code.
-Removed Theft Deterrent Fuel Shutoff ability, I was recieving the 1216(cant remember exact #) theft signal, but I disabled it with DHP tuner and the code is gone now.
-Fuel filter was replaced a months ago but fuel pressure seems good initially as I can rev the motor and RPM goes up just fine dies at 3-4 seconds limit.
-Checked 5vdc getting to the tps
-Inspected vac lines for possible leaks
I'm in the middle of checking the continuity from the TPS dk. blue wire to the PCM, but currently raining like hell every other five minutes so its been tough to get back out. Is the bogus Theft/Owner deterrent system still causing issues and just not throwing a code? Anyone have any ideas or suggestions that may have come across this before?
