Mass flow sensor
Check the mass flow sensor, oil pressure sensor and fuel temperature sensor, along with the connectors and electrical cables in the circuit.Proceed as follows to verify that the fault has been rectified:There must not be any active fault codes for the voltage supply to sensors or for battery voltage.Start the engine and run it at idling speed for at least 15 seconds.If the fault has been rectified, the fault code becomes inactive. Clear the fault code.Switch the power off and on with the starter key three times in succession at 10 second intervals to extinguish the warning lamp.
What you'll see
No driver-visible symptom recorded.
System reaction
No system-reaction text recorded.
Diagnostic depth
