P0235 Fault in the boost pressure sensor wiring

By: · Updated:

P0235 means: Fault in the boost pressure sensor wiring. The boost pressure sensor measures pressure in the intake. Drive gently and have the car checked soon. The repair usually costs about €50–200 in Estonia. The most common cause: sensor is dirty with soot or oil.

What it means

The boost pressure sensor measures pressure in the intake. With this fault the engine computer often limits power. The engine computer isn't getting a proper signal from the sensor at all.

What could be wrong

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

  1. We compare the sensor reading with atmospheric pressure
  2. We clean the sensor or repair the wire
  3. We replace the sensor
