Hva betyr feilkoden?
The LPG control module monitors the signal from the pressure sensor in the intake manifold. The code is set when that signal is too low while engine speed is above a certain level.
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 ground in the signal wire
- Open circuit or short circuit to ground in the power supply wire
- Defective manifold pressure sensor in the intake manifold
Hva du kan gjøre
- 1With diagnostic equipment, read the intake manifold pressure while running on gas; a normal reading suggests the fault is not active now
- 2Check the connectors on the LPG control module and the pressure sensor for poor contact and oxidation
- 3Check the wires to the pressure sensor for chafing and damage, and use a multimeter to confirm the signal wire has no contact with ground
- 4Use a multimeter to confirm the supply wire to the pressure sensor has no contact with ground
- 5If no fault is found, have a workshop try replacing the pressure sensor in the intake manifold
- 6Erase the code and road test the car to see whether it returns
Symptomer du kan merke1
- Poor performance
