⁽¹⁾

There are two severity levels of misfire faults recognized by the PCM. The first is a catalyst damaging misfire which will cause the PCM to flash the MIL rapidly. The second is a misfire which will cause exhaust emissions to exceed standards. This fault will cause the PCM to constantly illuminate the MIL and store a DTC.

⁽²⁾	When DTC P1000 is received, a complete Drive Cycle must be performed to clear it. Refer to Section 2B, Drive Cycles, for details on performing the Drive Cycle. If DTC P1000 cannot be cleared, go to Section 6B, Pinpoint Test QC.
