Co oznacza ten kod błędu?

The engine control module compares the boost reading with atmospheric pressure, which the control module measures itself. If the difference between them becomes too large, the code is stored. The cause can be poor contact or damaged wiring to the sensor, but the boost sensor or the built-in pressure sensor may also be faulty.

Możliwe przyczyny

Looseness, contact resistance or oxidation in the connections
Break or short circuit in the wiring to the boost pressure sensor
Damaged boost pressure sensor
Damaged atmospheric pressure sensor inside the engine control module

Co możesz zrobić

1With the ignition off, inspect the boost sensor plug for looseness, contact resistance and oxidation
2Use a multimeter to check that the wiring to the boost pressure sensor has no break and no short to ground or supply voltage, moving the harness as you measure
3Check that the ground wire to the boost pressure sensor has no break
4Erase the fault code and test drive the car; if it returns, have a workshop replace the boost pressure sensor

Objawy, które możesz zauważyć1

Check engine lamp lights up or behaves abnormally

Na co może wpływać usterka1

A calculated boost pressure is used instead of the measured value
