Co oznacza ten kod błędu?
The code concerns neutral position sensor A and indicates that the character of its signal is wrong: the frequency of the signal is incorrect. The sensor sends its signal as a modulated pulse or frequency signal, and the fault is checked with the engine running. The sensor measures the angle of the gear lever against the gearbox input shaft.
Możliwe przyczyny
- Loose contact or oxidation in the connector
- Break in the signal wire
- Damaged neutral position sensor
Co możesz zrobić
- 1Check that the fuses are intact. The locations are shown in the instruction manual or on the fuse list
- 2Check that the connector at the sensor is firmly seated and free from looseness and oxidation
- 3Use a multimeter to check that the signal wire to the sensor has no break
- 4If you have a diagnostic tool, check in live data that the sensor signal changes as the gear lever is moved, rather than staying still
- 5If the fault remains after these checks, have a workshop with diagnostic equipment check the sensor signal
Objawy, które możesz zauważyć3
- Automatic engine stop-start does not work while driving
- Automatic engine stop-start does not work at idle
- Auto-start does not work
Na co może wpływać usterka1
- The automatic engine stop-start function is switched off
