Was bedeutet der Fehlercode?
At engine start the ECM stores the readings from the intake air, fuel and coolant temperature sensors and compares them. If the coolant temperature sensor reads too far below the others, the code is set.
Mögliche Ursachen
- The coolant temperature sensor is broken
- Poor contact in the connections, with resistance or oxidation
Was Sie tun können
- 1With diagnostic equipment, read the engine temperature at start and compare it with the intake air and fuel temperatures
- 2Disconnect the electric cooling fan connector before you begin, since the fan can run even when the ignition is off
- 3Check the coolant temperature sensor's connector for looseness, oxidation and contact resistance
- 4Check that the coolant level and freeze protection are in order, since a frozen sensor can read too cold
- 5Have a workshop replace the coolant temperature sensor if the connector is in good condition and the fault remains
Symptome, die Sie bemerken können2
- Malfunction indicator lamp (MIL) on
- The engine is hard to start
Was der Fehler beeinflussen kann1
- The engine temperature is calculated using a model
