Hva betyr feilkoden?
The engine control module (ECM) monitors reference voltage A to the sensors. The code is set when the module finds a voltage problem in any internal supply circuit to a component: too high, too low, or no voltage at all. The cause may be in the wiring or a sensor, but it can also be the engine control module itself.
Mulige årsaker
- Signal cable for the connected component short-circuited to supply voltage
- Open circuit in the signal cable for the connected component
- Signal cable for the connected component short-circuited to ground
- Supply cable to the sensor short-circuited to ground or supply voltage
- Damaged sensor
- Damaged engine control module (ECM)
Hva du kan gjøre
- 1Read the fault codes and first trace any stored codes for sensors supplied from the engine control module
- 2Check that the relevant fuses are intact and that the connectors to the engine control module and the sensors are secure, with no play or oxidation
- 3Use a multimeter to check that the wires from the engine control module to the sensors have no open circuit and are not shorted to ground or supply voltage
- 4If the wiring is intact and the fault remains, have a workshop determine whether a sensor or the engine control module is damaged
Symptomer du kan merke5
- Uneven idle and increased emissions
- Poor performance
- The engine stops while driving or misfires
- The engine is difficult to start
- The starter motor does not turn, or turns but the engine does not start
