Possible Causes

GOOD TRIP EQUAL TO ZERO

O2 SENSOR HEATER OPERATION

O2 HEATER ELEMENT

O2 SENSOR HEATER GROUND CIRCUIT OPEN

ASD RELAY OUTPUT CIRCUIT OPEN

PCM

DIAGNOSTIC PROCEDURE - P0135-1/1 O2 SENSOR HEATER FAILURE (6 CYLINDER)

TEST ACTION
1 Turn the ignition on.
With the DRBIII®, read DTC's.
Is the Good Trip display and equal to zero?
  1. Yes --> Go To 3
  2. No --> Go To 2
2 Turn the ignition off.
NOTE: Wait a minimum of 8 minutes to allow the O2 Sensor to cool down before continuing the test. Allow the O2 Sensor voltage to stabilize between 0.4 to 0.6 volts.

Turn the ignition on.
With the DRBIII®, actuate the O2 Heater Test.
With the DRBIII®, monitor O2 Sensor voltage for at least 2 minutes.
Does the voltage stay between 0.4 and 0.6 volts?
  1. Yes --> Go To 3
  2. No --> Refer to the INTERMITTENT CONDITION symptom in the Driveability category.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 .
3
NOTE: Allow the O2 sensor to cool down to room temperature.
Turn the ignition off.Disconnect the O2 Sensor harness connector.Measure the resistance across the O2 Sensor Heater element component side.
NOTE: O2 Sensor Heater Resistance Specification: 1/1 and 2/1 O2 Sensor 3.0 to 4.0 ohms 2/1 and 2/2 4.0 to 5.0 ohms.
Is the resistance between 4.0 and 7.0 ohms?
  1. Yes --> Go To 4
  2. No --> Replace the O2 Sensor.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 .
4 Turn the ignition off.
Disconnect the O2 Sensor harness connector.
Measure the resistance of the O2 Sensor Heater ground circuit in the O2 Sensor harness connector.
Is the resistance below 5.0 ohms?
  1. Yes --> Go To 5
  2. No --> Repair the open in the O2 Sensor Heater ground circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 .
5 Turn the ignition off.
Disconnect the O2 Sensor harness connector.
With the DRBIII®, actuate the O2 Heater Test.
Measure the voltage of the ASD Relay Output circuit in the O2 Sensor harness connector.
Is the voltage above 11.0 volts?
  1. Yes --> Go To 6
  2. No --> Repair the open in the ASD Relay Output circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 .
6
NOTE: Before Continuing: Disconnect the PCM harness connector and check the related wiring terminals for corrosion, damage or terminal push out. Repair as necessary.
Using the schematics as a guide, inspect the wire harness and connectors. Pay particular attention to all Power and Ground circuits.If there are no possible causes remaining, view repair.Repair:Replace and program the Powertrain Control Module in accordance with the Service Information.Perform POWERTRAIN VERIFICATION TEST VER - 5 .
