Applies To:

MIL Comes On With DTC P0133
(Supersedes 00-017, dated September 11, 2001)
Updated information is shown by asterisks and black bars.
SYMPTOM
The MIL comes on with DTC P0133 (primary heated oxygen sensor slow response).
PROBABLE CAUSE
*Some brands of fuel and/or fuel additive packages may create deposits at the fuel injector tips. This build-up may cause slight air/fuel deviations
between each cylinder. Build-up of these deposits, when coupled with very specific driving conditions, may cause the MIL to come on and the PCM to
store DTC P0133.*
CORRECTIVE ACTION
Replace the primary heated oxygen sensor (HO2S) and the fuel injectors.
For 1998-2000 models only: Compare the vehicle's ECM/PCM part number to PARTS INFORMATION. If the numbers do not match, replace the
ECM/PCM.
