| DTC P0116:00 |
CHT sensor circuit range/performance |
| DETECTION CONDITION |
- P0116:00 indicates the engine coolant temperature rationality test has failed. This DTC indicates that the CHT value is higher than the calibrated value and could prevent 1 or more OBD monitors from completing.
The PCM runs this logic after an engine off and a calibrated soak period (typically 6 hours).
This soak period allows the IAT and the CHT to stabilize and not differ by more than a calibrated value. DTC P0116:00 is set when all of the following conditions are met:
- The CHT at engine start exceeds the IAT at engine start by more than a calibrated value, typically 17 °C {31 °F}
.
- The CHT exceeds a calibrated value, typically 107 °C {225 °F}
.
- The fuel system, heated oxygen and misfire monitors have not completed.
- The calibrated time to set DTC P0116:00 has expired.
