DTC P2123:00 (PCM, SKYACTIV-G) DETECTION CONDITION AND POSSIBLE CAUSE
| System malfunction location |
APP sensor No. 1 circuit high input |
| Detection condition |
- The PCM monitors the input voltage from APP sensor No. 1. If the input voltage at the PCM terminal 2BN is above 4.9 V, the PCM determines that the APP sensor No. 1 circuit input voltage is high.
|
| Fail-safe |
- Regulates the upper limit of the APP sensor output.
|
| Possible cause |
- APP sensor connector or terminals malfunction
