P0106 – OBD-II DTC

OBD-II DTC P0106 – Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem

DTC P0106 meaning

DTC P0106 refers to a problem with the Manifold Absolute Pressure (MAP) or Barometric Pressure (BARO) circuit. This code indicates that the readings from the MAP sensor are outside the expected range or performance parameters. The MAP sensor measures the pressure inside the intake manifold, which is crucial for the engine control module (ECM) to calculate the correct air-fuel mixture for optimal engine performance.

DTC P0106 symptoms

Common symptoms associated with DTC P0106 may include:

• Check Engine Light illuminated
• Rough idling or stalling
• Decreased engine performance
• Poor fuel economy
• Increased emissions

DTC P0106 causes

Several factors can trigger DTC P0106, including:

• Faulty MAP sensor
• Vacuum leaks in the intake system
• Wiring issues or poor connections in the MAP sensor circuit
• Faulty ECM or software issues
• Clogged or dirty air filter

DTC P0106 seriousness

DTC P0106 can be considered serious as it affects engine performance and efficiency. If left unaddressed, it may lead to further engine damage, increased emissions, and potential failure to pass emissions tests. It is advisable to diagnose and repair the issue promptly to maintain vehicle reliability and performance.

How to diagnose DTC P0106

To diagnose DTC P0106, follow these steps:

1. Use an OBD-II scanner to confirm the DTC and check for any additional codes.
