What it means

The boost pressure sensor measures pressure in the intake. With this fault the engine computer often limits power. The sensor voltage is too low. Usually a wire is broken or a connector is loose.

What could be wrong

1Sensor is dirty with soot or oil
2Connector or wire
3Sensor has failed

What you can check yourself

Check the sensor connector. The sensor is usually on the intercooler pipe. You can do the simpler checks yourself.

How we fix it

We compare the sensor reading with atmospheric pressure
We clean the sensor or repair the wire
We replace the sensor
