Possible Causes

GOOD TRIP EQUAL TO ZERO

EXHAUST LEAK

O2 SENSOR SIGNAL CIRCUIT VOLTAGE DROP

O2 SENSOR GROUND CIRCUIT VOLTAGE DROP

O2 SENSOR

DIAGNOSTIC PROCEDURE - P0133-1/1 O2 SENSOR SLOW RESPONSE

TEST ACTION
1
NOTE: Check for contaminates that may have damaged the O2 Sensor: contaminated fuel, unapproved silicone, oil and coolant.
Turn the ignition on.With the DRBIII®, read DTC's.Is the Good Trip displayed and equal to zero?
  1. Yes --> Go To 2
  2. No --> Refer to the INTERMITTENT CONDITION symptom in the Driveability category.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 .
2 Start the engine.
Inspect the exhaust system for leak between the engine and the O2 sensors.
Are there any exhaust leaks?
  1. Yes --> Repair or replace the leaking exhaust parts as necessary.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 .

  2. No --> Go To 3
3
NOTE: Ensure the voltmeter leads meet the terminals in the connector and that there is good terminal to wire connection.
NOTE: Ensure the voltmeter leads are connected for positive polarity
Perform a voltage drop test by backprobing the O2 Sensor Signal circuit at the O2 Sensor harness connector and at the PCM harness connector.Start the engine.Allow the engine to idle.Is the voltage below 0.10 volt?
  1. Yes --> Go To 4
  2. No --> Repair the high resistance on the O2 Sensor Signal circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 .
4
NOTE: Ensure the voltmeter leads meet the terminals in the connector and that there is good terminal to wire connection.
NOTE: Ensure the voltmeter leads are connected for positive polarity
Backprobe between the O2 Sensor ground circuit at the O2 Sensor harness connector and PCM harness connector.Start the engine.Allow the engine to idle.Is the voltage below 0.10 volt?
  1. Yes --> Go To 5
  2. No --> Repair the high resistance on the (K127) O2 Sensor Ground circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 .
5 If there are no possible causes remaining, view repair.
Repair:
Replace the O2 Sensor
Perform POWERTRAIN VERIFICATION TEST VER - 5 .
