Co oznacza ten kod błędu?

The air temperature sensor in the intake pipe, downstream of the EGR inflow, measures the temperature of the intake air. The engine control module checks the sensor's DC voltage and sets the code when the value is wrong for too long. The fault is checked with the engine running, and while it is active a calculated value is used instead.

Możliwe przyczyny

Break in the signal wire
Signal wire shorted to earth
Damaged intake temperature 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 air temperature sensor in the intake pipe is firmly seated and free from looseness, contact resistance and oxidation
3Use a multimeter to check that the signal wire to the sensor has no break and is not shorted to earth (the body)
4Read off the fault code with the engine running and check whether it is still active
5If the fault remains after these checks, have a workshop investigate the sensor

Objawy, które możesz zauważyć1

The check engine lamp lights or behaves abnormally

Na co może wpływać usterka1

A calculated value is used instead of the sensor's value
