9 - 14 ENGINE - ELECTRICAL DIAGNOSTICS
(P0102) MASS AIR FLOW CIRCUIT (CONTINUED)
7.
5-VOLT SUPPLY CIRCUIT SHORT TO SENSOR GROUND CIRCUIT
With the ignition off.
Measure the resistance between the 5-Volt Supply circuit and the Sen-
sor Ground 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 5-Volt Supply circuit for a short to ground.
Perform POWERTRAIN VERIFICATION TEST - VER 2.
8.
5-VOLT SUPPLY 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 5-Volt Supply circuit at the MAF Sensor
harness connector.
Is the voltage below 1.0 volt?
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 5-Volt Supply circuit for a short to voltage.
Perform POWERTRAIN VERIFICATION TEST - VER 2.
9.
CHECK THE MAF SENSOR SIGNAL CIRCUIT VOLTAGE
With 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 12
No >> Go To 10
