⁽¹⁾	DTC requires 2 consecutive drive cycles to set MIL.

⁽²⁾	If this DTC is set, Engine Control Module (ECM) will enter fail-safe mode.

⁽³⁾	If misfire is sufficient enough to cause catalyst damage, Malfunction Indicator Light (MIL) should flash. If misfire is not sufficient enough to cause catalyst damage, DTC requires 2 consecutive drive cycles to set MIL
