Co oznacza ten kod błędu?
The ECM compares the signal from the camshaft sensor with the signal from the engine speed sensor and checks that it lies within a reasonable range. If the camshaft sensor signal does not match what is expected, fault code ECM-1808 is set.
Możliwe przyczyny
- Signal wire short-circuited to voltage
- Signal wire short-circuited to ground
- Open circuit in the signal wire or the supply wire
- Camshaft or engine speed sensor incorrectly installed
- Defective camshaft position sensor
- Defective engine speed sensor
Co możesz zrobić
- 1Switch off the ignition and check the camshaft sensor connector for play and oxidation
- 2With a multimeter, check that the signal wires from the camshaft and engine speed sensors have no break and are not shorted to ground or voltage
- 3Check that the camshaft and engine speed sensors are correctly mounted and not loose
- 4If you have a diagnostic tool: check in live data that the camshaft sensor signal follows engine speed with the engine idling
- 5If the fault remains, have a workshop replace the camshaft or engine speed sensor, depending on which is at fault
Objawy, które możesz zauważyć1
- The engine does not start
