(P0102) MASS AIR FLOW CIRCUIT (CONTINUED)
10.
MAF SENSOR SIGNAL CIRCUIT SHORT TO VOLTAGE
Turn the ignition off.
Disconnect the PCM C3 harness connector.
Note: Check connectors — Clean/repair as necessary.
Turn the ignition on.
Measure the voltage of the MAF Sensor Signal circuit at the MAF Sen-
sor harness connector.
Is the voltage below 1.0 volt?
Yes >> Go To 11
No >> Repair the MAF Sensor Signal circuit for a short to volt-
age.
Perform POWERTRAIN VERIFICATION TEST - VER 2.
11.
MAF SENSOR SIGNAL CIRCUIT SHORT TO 5-VOLT SUPPLY CIRCUIT
Turn the ignition off.
Measure the resistance between the MAF Sensor Signal circuit and
the 5-Volt Supply circuit at the MAF Sensor harness connector.
Is the resistance above 100 kohms?
Yes >> Replace and program the Powertrain Control Module.
(Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL
MODULES/POWERTRAIN
REMOVAL).
Perform POWERTRAIN VERIFICATION TEST - VER 2.
No >> Repair the MAF Sensor Signal circuit for a short to the
5-Volt Supply circuit.
Perform POWERTRAIN VERIFICATION TEST - VER 2.
12.
CHECK THE SENSOR GROUND CIRCUIT
Turn the ignition off.
Measure the resistance between ground and the Sensor Ground cir-
cuit.
Is the resistance below 5.0 ohms?
Yes >> Go To 14
No >> Go To 13
