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. 7 -  This voltage drop test will determine if high resistance has caused this DTC to set.
3. 9 -  This step verifies the voltage signal from the PCM to the MAF sensor connector.
4. 10 -  This step tests the signal circuit of the MAF sensor for a short to another 5-volt reference circuit.
5. 13 -  This step will determine which portion of the circuit or which component is shorted to ground.
6. 16 -  This step verifies that the signal circuit is not shorted to any other PCM circuit.
