* The ignition is ON, or the engine is operating.

* The ignition voltage is greater than 10 V.

* DTC P0100, P0102 and P0103 run continuously once the above conditions are met for 1 s.

Conditions for Setting the DTC

P0100

The ECM detects that the MAF sensor signal is 0.0 Hz.

P0102

The ECM detects that the MAF sensor signal is less than 1135 Hz.

P0103

The ECM detects that the MAF sensor signal is greater than 15,152 Hz.

Action Taken When the DTC Sets

DTCs P0100, P0102, and P0103 are Type B DTCs.

Conditions for Clearing the DTC

DTCs P0100, P0102, and P0103 are Type B DTCs.

Diagnostic Aids

* Inspect the harness of the MAF sensor to verify that it is not routed too close to the following components:

- The secondary ignition wires or coils

- Any solenoids

- Any relays

- Any motors

* Inspect the hydro-carbon (HC) absorber, if equipped, in the air cleaner assembly for ruptures that would leak charcoal into the air intake,

contaminating the sensing element.

* Inspect for any contamination, water intrusion, or debris on the sensing elements of the MAF sensor. If debris is present, clean the sensor. If

the sensor cannot be cleaned, replace the sensor.

* A high resistance may cause a driveability concern before this DTC sets.
