DTC Set Conditions
- Check Conditions - At least 20 seconds have passed since the last monitor was complete. Engine coolant temperature is higher than 169°F (76°C). Engine speed is at between 1000-1800 RPM (M/T) or 880-1800 RPM (A/T). Intake air temperature is higher than 32°F (0°C). Barometric pressure is higher than 11 psi (76 kPa). Vehicle speed is 0.9 mph (1.5 km/h - M/T) or 18.7 mph (30 km/h - A/T) or more. At least 90 seconds have passed since manifold differential pressure sensor output voltage fluctuated 1.5 volt or more. The throttle valve is closed. Volumetric efficiency is lower than 15% (M/T) or 25% (A/T). While fuel is being shut off (M/T). 20 seconds have elapsed from the start of the previous monitoring. Monitoring time: 2 seconds x 3 times.
- Judgement Criteria - When intake manifold pressure fluctuation width is lower than 0.37 psi (2.6 kPa). When the EGR solenoid is turned ON.
