DTC Detection Logic
Rationally incorrect voltage is sent to ECM compared with the signals from APP sensor 1 and APP sensor 2.
| DTC | CONSULT screen terms (Trouble diagnosis content) |
DTC detection condition | |
| P2138 | APP SENSOR (Throttle/Pedal position sensor/switch "D" / "E" voltage correlation) |
Diagnosis condition | Start engine and let it idle |
| Signal (terminal) | APP sensor 1 signal and APP sensor 2 signal | ||
| Threshold | Rationally incorrect voltage is sent to ECM compared with the signals from APP sensor 1 and APP sensor 2 | ||
| Diagnosis delay time | - | ||
