P0068 Mitsubishi Code - Manifold Absolute Pressure/Mass Air Flow Sensor - Throttle Position Correlation

Quick Answer

The P0068 diagnostic trouble code (DTC) for Mitsubishi vehicles refers to a correlation problem between the Manifold Absolute Pressure (MAP) sensor, Mass Air Flow (MAF) sensor, and Throttle Position Sensor (TPS). Common causes include Faulty MAP sensor, Faulty MAF sensor, Faulty TPS. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0068 Mitsubishi Description

The P0068 diagnostic trouble code (DTC) for Mitsubishi vehicles refers to a correlation problem between the Manifold Absolute Pressure (MAP) sensor, Mass Air Flow (MAF) sensor, and Throttle Position Sensor (TPS). These sensors play crucial roles in determining the air intake and throttle position of the engine, which are essential for fuel delivery and engine performance. When these sensors are not working together properly, it can lead to incorrect air-fuel mixture calculations and affect the engine's performance.

  • P0068 ....my Mitsubishi Chariot-Grandis 1998 has got the symptoms. Show me a diagram or illustration of the throttle position correlation. Thanks.

    Reply to Comment

  • There is no diagram or illustration for a correlation problem. The code means that one of the sensor ( Manifold Absolute Pressure/Mass Air Flow Sensor or Throttle Position sensor ) it's not reading the correct values. Either one of the sensor may be faulty.
