P0106 Manifold absolute pressure / barometric pressure sensor range/performance

What P0106 means

The MAP sensor is sending a signal, but it does not match what the engine computer expects for the current throttle position and engine speed. The computer may then calculate load and fuelling incorrectly.

P0106 is a generic SAE J2012 code: it means the same on every make. The exact cause still depends on the car, so read the freeze-frame data before replacing parts.

Symptoms

Common causes

  1. Leaking, split or blocked vacuum hose to the sensor
  2. Intake vacuum leak or, on turbo engines, a boost leak
  3. Sensor contaminated with oil or soot
  4. Worn or failing MAP sensor
  5. Low engine vacuum from a mechanical fault such as incorrect valve timing

Can I keep driving with P0106?

You can drive, but get it checked within a week. Load is miscalculated, which costs fuel and can make the engine hesitate.

What to check first

  1. With the key on and engine off, compare the MAP reading with barometric pressure; they should be close.
  2. At idle on a petrol engine, check that the MAP reading drops well below atmospheric pressure and responds quickly to throttle blips.
  3. Inspect the vacuum hose and intake for leaks; remove and clean the sensor port if it is clogged with oil or soot.
  4. Replace the sensor if readings stay implausible with a sound intake.
