Code Enable Criteria

For DTC to run, the following conditions must be met:

• DTCs P0101, P0102, P0103, P0107, P0108, P0117, P0118, P0121, P0122, P0123, P0125, P0336, P0341, P0502, P0503, P1106, P1107, P1114, P1115, P1121, P1122, P1336, or P1374 are not set.
• Engine speed is 550-5850 RPM.
• System voltage is 9-18 volts.
• Engine coolant temperature is 21-248°F (-6 to +120°C).
• Throttle angle is steady.

DTC will set when PCM is detecting a crankshaft RPM variation indicating a misfire sufficient to cause 3-way catalytic converter damage or emissions levels to exceed the mandated standard.
