| POSSIBLE CAUSE |
- APP sensor connector or terminals malfunction
- Short to ground in wiring harness between APP sensor terminal E and PCM terminal 1X
- PCM connector or terminals malfunction
- Short to power supply in wiring harness between APP sensor terminal E and PCM terminal 1X
- Open circuit in wiring harness between APP sensor terminal E and PCM terminal 1X
- APP sensor No. 2 malfunction
