What does this fault code mean?
The code reports a signal from the exhaust pressure sensor that is too low. The ECM checks the signal, and the fault may be an open circuit in the signal wire, a short to ground, or a faulty sensor.
Possible causes
- Open circuit in the signal wire
- Signal wire short-circuited to ground
- The exhaust pressure sensor is faulty
What you can do
- 1Look for chafing or pinch damage on the signal wire to the exhaust pressure sensor
- 2Use a multimeter to check that the signal wire is not short-circuited to ground
- 3Check that the connector to the exhaust pressure sensor is secure and free from oxidation
- 4If you have a diagnostic tool, read the exhaust pressure sensor value with the ignition on and see whether it is unreasonably low
- 5If the wiring is sound and the fault remains, have a workshop check or replace the exhaust pressure sensor
Symptoms you may notice1
- The engine warning lamp lights up or behaves abnormally
What the fault can affect1
- EGR control is lost
