Skill Level:

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.
DIAGNOSIS
Connect the HDS to the DLC (data link connector) and read the stored DTC(s).
^
If DTC P0420 is the only code, go to REPAIR PROCEDURE.
^
If other DTCs are stored along with P0420 troubleshoot those codes first. Failure of other components could contribute to the failure of the catalytic
converter, and could cause it to fail again. Then go to REPAIR PROCEDURE.
REPAIR PROCEDURE
1.
Accord only: Determine the emissions type (KA or KL) of the vehicle. Either do a VIN Status Inquiry on iN, or examine the catalytic converter.
On a KA emissions type vehicle, the secondary oxygen sensor is in the middle of the converter. On a KL emissions type vehicle, the oxygen sensor
is in the rear of the converter.
2.
Replace the catalytic converter. If the mounting bolts do not break due to corrosion when you remove the original upper and lower covers, then
reuse the covers. Otherwise, replace the covers and the mounting bolts.
