P0111 IAT SENSOR - DTC DESCRIPTION
| DTC | M.U.T.-III SE screen terms (Trouble diagnosis content) | DTC detection condition | |||
|---|---|---|---|---|---|
| P0111 | 00 | I AT SENSOR 1 B1 (Intake air temperature sensor 1 circuit range/performance bank 1) |
A | Diagnosis condition | Ignition switch ON |
| Signal (terminal) | Intake air temperature sensor signal | ||||
| Threshold | Output temperature of intake air temperature sensor is excessively high or low | ||||
| Diagnosis delay time | 5 seconds | ||||
| B | Diagnosis condition | Engine cold start | |||
| Signal (terminal) | Intake air temperature sensor signal | ||||
| Threshold | The comparison result of signals transmitted to ECM from each temperature sensor (IAT sensor, ECT sensor, FTT sensor, and EOT sensor) shows that the voltage signal of the IAT sensor is higher/lower than that of other temperature sensors when the engine is started with its cold state | ||||
| Diagnosis delay time | - | ||||
