DTC P0222 [WL-C, WE-C (Australian, European (L.H.D. U.K.) specs.)]

id0102c4806000

DTC P0222

Accelerator pedal position (APP) sensor No.2 circuit low input
DETECTION CONDITION
•  The PCM monitors the input signal from APP sensor No.2. If the voltage from APP sensor No.2 is less than 0.29 V for 0.5 s when the APP sensor No.2 power supply voltage is normal, the PCM determines that there is a malfunction in the APP sensor No.2 circuit.
POSSIBLE CAUSE
•  APP sensor No.2 malfunction
•  Connector or terminal malfunction
•  Open circuit in wiring harness between APP sensor No.2 terminal A and PCM terminal 213
•  Short to ground in wiring harness between APP sensor No.2 terminal A and PCM terminal 213
•  Open circuit in wiring harness between APP sensor No.2 terminal C and PCM terminal 209
•  Short to ground in wiring harness between APP sensor No.2 terminal C and PCM terminal 209
•  PCM malfunction
