P0068 GMC code

What the P0068 code means. This code means that the manifold absolute pressure or mass air flow sensors that detect air flow through the air induction system and the intake manifold have readings that contradict the readings that are coming from the throttle position sensor.

What does trouble code P0068 mean?

Diagnostic trouble code (DTC) P0068 stands for “MAP/MAF – Throttle Position Correlation.” If the readings from one or more of these sensors contradict the data presented by the other devices, the vehicle’s computer, aka the powertrain control module (PCM), logs the OBD-II trouble code P0068.

What is MAP MAF throttle position correlation?

OBD-II Code P0068 is defined as a MAP/MAF – Throttle Position Correlation. The Manifold Absolute Pressure (MAP) Sensor tells the engine control module (PCM) how much pressure is in the engine manifold. The Mass Airflow Sensor (MAF) tells the PCM how much air is actually flowing through the engine.

How do I fix error P0068?

Repairs that can fix the P0068 code would include:

  1. Adjusting the mounting or installation of the mass air flow sensor, manifold absolute pressure sensor, or throttle position sensor.
  2. Replacing the mass air flow sensor.
  3. Replacing the manifold absolute pressure sensor.

How do I fix code p0102?

Zitat von Youtube: You can spray the maf sensor cleaner onto the wire perpendicularly to the ground so that it won't damage the maf sensor reinstall the maf sensor back in the car after it gets dry.

Where is the throttle sensor position located?

butterfly spindle/shaft

A throttle position sensor (TPS) is a sensor used to monitor the air intake of an engine. The sensor is usually located on the butterfly spindle/shaft, so that it can directly monitor the position of the throttle. More advanced forms of the sensor are also used.

What is MAF sensor?

A device in the throttle body, the mass airflow, or MAF, sensor helps the engine computer determine the proper air-fuel mixture by measuring the mass of the air flowing past it.
