December 17, 2002
Applies To:
1998-02 Accord DX and L4 EX/LX LEV - ALL
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.
PARTS INFORMATION
TOOL INFORMATION
02 Sensor Wrench: T/N SNAP-ON YA5575 or SP Tools 93750 or equivalent (commercially available).
WARRANTY CLAIM INFORMATION
In warranty:
The normal warranty applies.
Out of warranty:
Any repair performed after warranty expiration may be eligible for goodwill consideration by the District Parts and Service Manager or your Zone Office. You must request consideration, and get a decision, before starting work.
REPAIR PROCEDURE
1. Confirm the DTC with the PGM Tester.
2. Replace the fuel injectors (see page 11-97 in the 1998-2002 Accord Service Manual).
3. Replace the primary H02S (see page 11-99 in the service manual).
*^ For 2001-02 models, the repair procedure is complete. Return the vehicle to the customer.
^ For 1995-2000 models, go to step 4.*
4. Find the ECM/PCM part number, and compare it to the part numbers in PARTS INFORMATION.
^ If the ECM/PCM part number is the same, return the vehicle to the customer.
^ If the ECM/PCM part number is different, go to step 5.
5. For 2000 model only: Download the immobilizer codes from the ECM/PCM with the PGM Tester. Refer to "Rewriting a New ECM/PCM" in Service Bulletin 00-049, Immobilizer System (Type 2), found under Body Electrical.
6. Remove the ECM/PCM.
7. Replace the ECM/PCM in the reverse order of removal.
8. Rewrite the immobilizer codes into the PCM with the PGM Tester. Refer to "Rewriting a New ECM/ PCM" in Service Bulletin 00-049, Immobilizer System (Type 2), found under Body Electrical.
