Co oznacza ten kod błędu?
In the engine control module (ECM) the outside air temperature is compared with a calculated temperature. If the signal is lower than the calculated one, the fault is set, even though the signal itself lies within its normal range. The fault is only checked after a longer drive.
Możliwe przyczyny
- Contact resistance in the connections
- Damaged outside air temperature sensor
- Damaged intake air temperature sensor
- The cause may lie in the central electronics module (CEM)
Co możesz zrobić
- 1If the fault code for the intake air temperature sensor is also stored, troubleshoot this code first
- 2Check the outside air temperature sensor connector for contact resistance and oxidation
- 3If you have a diagnostic tool: compare the outside temperature in live data with the intake temperature after the car has stood still for a while; they should be roughly equal
- 4Check that the outside air temperature sensor is seated properly, and have a workshop measure its resistance if needed
- 5Clear the CEM fault code once it has been fixed, and read the fault codes there first, since this code cannot be cleared until the CEM fault is gone
Objawy, które możesz zauważyć3
- Engine warning lamp comes on
- Starting problems, the engine cranks slowly
- The outside temperature gauge does not work or shows wrong values
Na co może wpływać usterka1
- The engine uses the value from the intake air temperature sensor
