DTC P1122 - TP SENSOR CIRCUIT INTERMITTENT LOW VOLTAGE Oldsmobile Cutlass VI

Testing & Diagnostics

Note. For circuit reference, see the appropriate WIRING DIAGRAMS article. For connector and terminal identification, see CONNECTOR IDENTIFICATION .

Circuit Description

Throttle Position (TP) sensor measures amount of throttle opening. PCM uses TP sensor information for fuel delivery calculations. TP sensor readings during acceleration are much higher than those during deceleration or idle. DTC P1121 sets if PCM senses TP sensor voltage intermittently less than 0.16 volt.

Conditions required to set DTC are

Ignition on.
TP signal voltage is intermittently less than 0.16 volt.
