Hva betyr feilkoden?
The LPG control module monitors the signal from the pressure sensor in the intake manifold and sets the code when that signal is too high while the engine is running.
Mulige årsaker
- Contact resistance or oxidation in the connector on the LPG control module
- Contact resistance or oxidation in the connector on the pressure sensor
- Open circuit or short circuit to supply voltage in the ground wire
- Short circuit to supply voltage in the signal wire
- Defective manifold pressure sensor in the intake manifold
Hva du kan gjøre
- 1Start the engine and read the intake manifold pressure with diagnostic equipment; if the pressure looks normal, the fault has probably been present but is not active at the moment
- 2Check the connectors on the LPG control module and the pressure sensor for poor contact and oxidation
- 3Check the signal wire for chafing and damage, and use a multimeter to confirm it has no contact with supply voltage
- 4Check the ground wire to the pressure sensor for breaks, and use a multimeter to confirm it has no contact with supply voltage
- 5Have a workshop try replacing the pressure sensor in the intake manifold if no fault is found
Symptomer du kan merke1
- Poor performance
