P0105 Fault in the intake pressure (MAP) sensor wiring

By: · Updated:

P0105 means: Fault in the intake pressure (MAP) sensor wiring. The MAP sensor measures pressure in the intake. Drive gently and have the car checked soon. The repair usually costs about €40–200 in Estonia. The most common cause: sensor is dirty with soot or oil (especially on diesels).

What it means

The MAP sensor measures pressure in the intake. The engine computer uses it to work out how much fuel to inject. 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 (especially on diesels)
  2. 2Connector or wire
  3. 3Sensor hose is loose or split
  4. 4Sensor has failed

What you can check yourself

Check the sensor connector and hose. The sensor is on the intake manifold or 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
