(P0135) O2 SENSOR 1/1 HEATER CIRCUIT HIGH (CONTINUED)
3.
O2 SENSOR HEATER OPERATION
Turn the ignition off.
Note: Allow the O2 Sensor to cool down before continuing the
test. Raising the hood may help in reducing under hood temper-
atures.
Connect a jumper wire between ground and the Oxygen Sensor
Heater Control circuit at the PCM harness connector leaving the har-
ness connector connected to the PCM.
Turn the ignition on.
With the DRB III , monitor O2 Sensor voltage for at least 2 minutes.
CAUTION: Remove the jumper wire after this Step is complete.
Does the voltage stay above 0.47 volt?
Yes >> Go To 4
No >> Go To 7

O2 HEATER ELEMENT
Note: Check the Engine Control Fuse 2 in the Relay Control Mod-
ule. If it is open, multiple DTCs will be set in the PCM. Determine
the cause of the open fuse before continuing using the wiring
diagrams/schematics as a guide.
Turn the ignition off.
Note: Allow the O2 Sensor to cool down to room temperature.
Raising the hood may help in reducing under hood temperatures.
Disconnect the O2 Sensor harness connector.
Note: Check connectors — Clean/repair as necessary.
Measure the resistance of the O2 Sensor Heater element.
Note: O2 Sensor Heater Resistance Specification: 8.5 to 9.5
ohms.
Is the resistance within specifications?
Yes >> Go To 5
No >> Replace the O2 Sensor. (Refer to 14 - FUEL SYSTEM/
FUEL INJECTION/O2 SENSOR - REMOVAL).
Perform POWERTRAIN VERIFICATION TEST - VER 2.
