P0106 Fault Code

Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem

• What does that mean?
• Symptoms
• Causes
• Solutions

The P0106 code indicates a problem with the Manifold Absolute Pressure (MAP) or Barometric Pressure (BARO) sensor circuit. This sensor plays a crucial role in measuring the engine's load, allowing the engine control module (ECM) to adjust fuel delivery and ignition timing. If the readings from this sensor are out of the expected range, it can lead to performance issues and affect overall engine efficiency.

What are the symptoms of the P0106 code?

• Poor engine performance or reduced power
• Increased fuel consumption
• Check Engine Light (CEL) illuminated
• Rough idling or engine stalling
• Unusual engine sounds or vibrations

What causes the P0106 code?

• Faulty MAP sensor or BARO sensor
• Electrical issues such as damaged wiring or poor connections
• Vacuum leaks in the intake manifold
• Failure of the ECM
• Faulty intake manifold pressure sensors

How to fix P0106?

• Inspect the MAP and BARO sensor, replacing if faulty.
• Check for and repair any damaged wiring or loose connections.
• Test for vacuum leaks in the intake manifold and repair as necessary.
• Update or replace the ECM if it is not functioning correctly.
• Clear the engine codes and test drive the vehicle to ensure the issue is resolved.
