    Skill Level: Repair Technician

    DIAGNOSIS

    1. Connect the HDS to the vehicle and check forDTCs P0420 or P0430.NOTE: In addition to DTCs P0420 or P0430, youmay also see DTCs P2243 or P2247 stored; the tipmay have broken off the primary A/F sensor.

    2. Remove the primary A/F sensor on top of theaffected catalytic converter. For example: If DTCP0420 is stored remove the rear (bank one)primary A/F sensor.
