DTC Set Criteria

There are 3 monitors, 2 seconds each, during each drive cycle. At least 20 seconds have passed since last monitor was complete. On 2.4L, engine coolant temperature is more than 180°F (82°C), engine speed is 940-2000 RPM, and volumetric efficiency is less than 20 percent. On 3.0L, engine coolant temperature is more than 141°F (77°C), engine speed is 910-1650 RPM and volumetric efficiency is less than 28 percent. On all vehicles, intake air temperature is more than 41°F (5°C), barometric pressure is more than 11 psi (76 kPa), and vehicle speed is 19 MPH or more. At least 90 seconds have passed since manifold differential pressure sensor output voltage fluctuated 1.5 volts or more. Throttle valve is closed. Code will be set if pressure fluctuations are minimal when EGR solenoid is turned on.
