Detection Condition
PCM measures purge line pressure/vacuum. DTC is set, if vacuum between charcoal canister and intake manifold does not reach a predetermined specification. Monitoring is performed when following monitoring conditions are met:
Monitoring Conditions
- Engine speed 1100-2700 RPM.
- Throttle opening angle 11-25 percent.
This is an intermittent monitor (Evaporative system 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 PCM.
