Test Description

The numbers below refer to the step numbers in the diagnostic procedures.

1. 5
   
   This step will determine if any mechanical faults have caused this DTC to set.
2. 9
   
   This step verifies the signal circuit from the MAF sensor electrical connector to the PCM. A voltage reading of less than 4 volts or more than 6 volts indicates a malfunction in the wiring or a poor connection.
3. 10
   
   This step tests the signal circuit of the MAF sensor for a short to another 5-volt reference circuit.
4. 16
   
   This step verifies that the signal circuit is not shorted to any other PCM circuit.
