DTC P0122: - Throttle/Pedal Position Sensor A Circuit Low

DTC P0122: - THROTTLE/PEDAL POSITION SENSOR A CIRCUIT LOW

For Vehicles With an Idle Air Control (IAC) Valve
Description:	The throttle position (TP) sensor circuit is monitored by the PCM for a high TP rotation angle (or voltage) input through the comprehensive component monitor (CCM). The test fails if the TP rotation angle (or voltage) changes above the maximum calibrated limit.
Possible Causes:	TP sensor not seated correctly TP circuit open to PCM VREF open to TP sensor TP circuit short to GND Damaged TP sensor
Diagnostic Aids:	This concern exhibits a symptom of limited power. A TP PID reading less than 3.42% (0.17 volt) in ignition ON, engine OFF or ignition ON, engine running indicates a concern is present.
For All others
Description:	The electronic throttle control (ETC) throttle position (TP) sensor 1 circuit was flagged as a concern by the powertrain control module (PCM) indicating a low voltage or open circuit.
Possible Causes:	Open ETC TP sensor harness Short to ground in the ETC TP sensor harness Damaged TP sensor SIG RTN circuit open to the TP sensor
Diagnostic Aids:	This concern exhibits a symptom of limited power. A TP1 PID reading less than 0.25 volt in ignition ON, engine OFF or ignition ON, engine running indicates a concern is present.
