4.
O2 SIGNAL CIRCUIT
Turn the ignition off
Disconnect the O2 Sensor harness connector.
Note: Check connectors — Clean/repair as necessary.
Turn the ignition on.
Measure the voltage of the O2 Signal circuit at the O2 Sensor harness
connector.
Is the voltage approximately 0.47 volt?
Yes >> Go To 5
No >> Check the O2 Signal circuit for damage, short to ground,
open, or short to voltage. If OK, replace and program the
Powertrain Control Module. (Refer to 8 - ELECTRICAL/
ELECTRONIC
CONTROL MODULE - REMOVAL).
Perform POWERTRAIN VERIFICATION TEST - VER 2.
5.
SENSOR GROUND CIRCUIT
Turn the ignition off.
Disconnect the PCM harness connectors.
Note: Check connectors — Clean/repair as necessary.
Measure the resistance of the Sensor Ground circuit from the O2 Sen-
sor harness connector to the PCM harness connector.
Is the resistance below 5.0 ohms?
Yes >> Replace the Oxygen Sensor. (Refer to 14 - FUEL SYS-
TEM/FUEL INJECTION/O2 SENSOR - REMOVAL).
Perform POWERTRAIN VERIFICATION TEST - VER 2.
No >> Check the Sensor Ground circuit for damage, short to
ground, open, or short to voltage. If OK, replace and pro-
gram the Powertrain Control Module. (Refer to 8 - ELEC-
TRICAL/ELECTRONIC
