DRIVEABILITY - GAS
P0133-1/1 O2 SENSOR SLOW RESPONSE —
TEST
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?
Yes → Go To 2
No
2 Start the engine.
Inspect the exhaust system for leak between the engine and the O2 sensors.
Are there any exhaust leaks?
Yes → Repair or replace the leaking exhaust parts as necessary.
No
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?
Yes → Go To 4
No
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?
Yes → Go To 5
No
5 If there are no possible causes remaining, view repair.
