DTC Set Criteria
- At least 5 seconds have passed since engine started. On Federal vehicles, engine speed is 400-6000 RPM. On California vehicles, engine speed is 440-4500 RPM. On all vehicles, engine coolant temperature is more than 14°F (-10°C). Intake air temperature is more than 14°F (-10°C). Barometric pressure is more than 11 psi (76 kPa). Adaptive learning is complete for the vane which generates Crankshaft Position (CKP) signal. Engine is running and there is no gear shifting, deceleration, sudden acceleration or A/C compressor switching occurring. Misfire is determined by change in angular velocity of CKP sensor. Code will set if misfire occurred in 4 or more of last 200 revolutions when catalytic converter temperature is more than 1742°F (950°C) (severe misfire which will cause MIL to flash continuously). Also, code will set if misfire occurred in 20 or more of last 1000 revolutions.
