Manifold Absolute Pressure (MAP) / Mass Air Flow (MAF) Throttle Position Correlation

Trouble Code: P0068
Address: 0x0068
System: Powertrain
Subsystem: Fuel & Air metering, Auxiliary emission controls
Technical Description:

Possible Causes:
  • Vacuum leaks between the mass airflow sensor and intake manifold and loose or cracked hoses
  • Dirty air cleaner
  • Leak in the intake manifold or sections
  • Faulty sensor
  • Coked intake runner behind throttle body
  • Poor or corroded electrical connectors
  • Obstruction to air flow
  • Defective electronic throttle body
  • Obstruction in hose from intake manifold to MAP sensor

Possible Symptoms:
  • The service engine soon or check engine light will illuminate.
  • Rough running engine – the computer will set the above code and additional codes depicting the faulty sensor if the problem is electrical.Without the correct airflow the engine will develop a rough idle, and depending on the severity, it may not accelerate or have a serious dead spot off idle. In short, it will run lousy
