Air Metering & Sensor Input Codes

Mass-airflow, intake-air-temperature, and manifold sensor faults that can make the PCM calculate the wrong fuel and spark strategy.

P0100-P0119

How to Use This Group

Start by reading all stored and pending codes together. A companion lean, misfire, EVAP, or oxygen-sensor code can change which test should come first.

Codes in This Group

P0101 Mass Air Flow Sensor Range/Performance The PCM sees mass-airflow data that does not match expected engine load. P0113 Intake Air Temperature Sensor Circuit High The PCM sees an intake-air-temperature signal that is higher than the normal circuit range. P0340 Camshaft Position Sensor Circuit The PCM sees an electrical or signal fault in a camshaft position sensor circuit.
