Supply pressure sensor
â–¶ How to fix
Check the fuel supply pressure sensor, coolant temperature sensor, charge air pressure sensor, charge air temperature sensor and fan speed sensor, along with the connectors and electrical cables in the circuit.
What you'll see
No driver-visible symptom recorded.
System reaction
No system-reaction text recorded.
Diagnostic depth
Detection
The voltage in the circuit has been above the permitted level.
Possible cause
Open circuit in the sensor circuit. The fault may also be caused by a fault on the voltage supply to those components which share their voltage supply. If a fault is indicated on the oil pressure sensor at the same time, there is probably a fault on the shared internal voltage supply.
