| P0111 | 00 |
IAT 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 | An excessively high or low temperature output from the sensor is sent to ECM. | ||||
| 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 | — | ||||
POSSIBLE CAUSE
-
Harness or connectors (High or low resistance in the IAT sensor circuit)
-
