Fuel temperature sensor
â–¶ How to fix
Check the fuel temperature sensor, oil pressure sensor and mass flow sensor, along with the connectors and electrical cables in the circuit.
What you'll see
No driver-visible symptom recorded.
System reaction
There is a common power supply for the fuel temperature sensor, oil pressure sensor and mass flow sensor. If a fault occurs in one of the sensors, this can affect the circuits of the other sensors.If the voltage is outside the permitted range, the control unit uses a preprogrammed value.
Diagnostic depth
Detection
The voltage in the circuit has been below the permitted level.
Possible cause
Possible causes:- Short circuit in the fuel temperature sensor circuit. - Fault in the oil pressure sensor circuit or mass flow sensor circuit.
