harness connector.
Is the voltage between 4.7 and 5.2 volts?
Yes >> Replace and program the Powertrain Control Module.
(Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL
MODULES/POWERTRAIN
REMOVAL).
Perform POWERTRAIN VERIFICATION TEST - VER 2.
No >> Go To 7
7.
MEASURE THE 5-VOLT SUPPLY CIRCUIT VOLTAGE WITH OIL SENSOR DISCONNECTED

Yes >> Replace the Engine Oil Sensor. (Refer to 9 - ENGINE/LU-
BRICATION/OIL - REMOVAL).
Perform POWERTRAIN VERIFICATION TEST - VER 2.
No >> If the voltage is above 5.2 volts, Go To 8
If the voltage is below 4.7 volts, Go To 9
8.
5-VOLT SUPPLY 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 MAP Sensor
harness connector.
Is the voltage below 1.0 volt?
