Detection Condition

DTC is set when Powertrain Control Module (PCM) detects high pressure (no vacuum) in fuel tank, measured immediately after purge control is stopped with Canister Drain Cut Valve (CDCV) closed. This is monitored when following Condition are met:

• Fuel tank pressure is -.29 IN. Hg (-0.99 kPa)
• Fuel remaining is 15-85 percent of total capacity.
• Intake air temperature is 14-140°F (-10-60°C) when engine is first started.
• Engine coolant temperature is 14-95°F (-10-35°C) when engine is first started.
• Atmospheric pressure is more than 21.3 IN. Hg (72.4 kPa).
• Vehicle speed is 24.5-65.4 MPH (120.3 km/h).
• Engine speed is 1000-4000 RPM.
• Calculated load is 9.4-65 percent.
• Throttle opening angle is 3.13-31.6 percent.
• Intake air temperature is 14-140°F (-10-60°C) during monitoring.
• Engine coolant temperature is 158-212°F (70-100°C) during monitoring.

This is an intermittent monitor (Evaporative leak monitor). MIL illuminates if PCM detects malfunction condition in 2 consecutive drive cycles. Diagnostic Monitoring Test Results and Pending Code are stored if PCM detects malfunction condition during first drive cycle. Freeze Frame Data is available and DTC is stored in the PCM memory.
