WARNING: This page is about a different car, the 2003 Mazda MPV and 2002 Mazda MPV. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
If EVAP System Repair Verification Drive Mode cannot be performed because vehicle cannot be driven under conditions specified for this test, perform evaporative system test procedure as an alternative. See FUEL EVAPORATIVE SYSTEM (MPV)
under EMISSION SYSTEMS & SUB-SYSTEMS in SYSTEM & COMPONENT TESTING - MAZDA6, MIATA, MPV, PROTEGE & PROTEGE5 article. Mode 6 can be performed regardless of RFCFLAG condition.
- Ensure following PIDs are within following specifications:
- BARO: 21.3 in. Hg (72.3 kPa)
- FTL: .5-2.5 volts
- IAT: 41-95°F (5-35°C)
- VPWR: 10.9-14.6 volts
All PIDs must be within specification before engine is started to initiate evaporative emission test. Go to next step.
- Using scan tool, clear DTCs from memory. See CLEARING DIAGNOSTIC TROUBLE CODES . Start engine and allow to idle for more than 10 seconds. Turn ignition off. Wait for 5 hours or more.
- Start engine and increase RPM to 3500 to warm up to normal operating temperature. Allow engine to idle for more than 15 minutes. Drive vehicle at 40-50 MPH for more than 5 minutes. Stop vehicle and turn ignition off. Wait 20 minutes or more. Start engine. Access ON BOARD SYSTEM READINESS menu of GENERIC OBD II FUNCTIONS to check Drive Mode completion status. Test is complete when Readiness Function Check (RFC) flag changes from NO to YES. Go to next step. If test is not complete, turn ignition off and go back to step 1.
