DTC P2122: Notes

DTC P2122 [L3] CHART

DTC P2122	Accelerator pedal position (APP) sensor No. 1 circuit low input
DETECTION CONDITION	The PCM monitors the input voltage from APP sensor No. 1 when the engine is running. If the input voltage is less than 0.12 V , the PCM determines that the APP sensor No. 1 circuit input voltage is low. Diagnostic support note This is a continuous monitor (CCM). MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle. FREEZE FRAME DATA is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	APP sensor No. 1 malfunction Connector or terminal malfunction Open circuit in wiring harness between APP sensor terminal A and PCM terminal 1AE Short to body ground in wiring harness between APP sensor terminal A and PCM terminal 1 AE Open circuit in wiring harness between APP sensor terminal B and PCM terminal 1Y Short to body ground in wiring harness between APP sensor terminal B and PCM terminal 1Y PCM malfunction
