Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
DTC Confirmation Test (Using Generic Scan Tool)
- Lift up drive wheels. Start engine (VDC switch "OFF") and warm to normal operating temperature. Turn ignition off and wait at least 10 seconds. Start engine and wait at least 70 seconds. Set voltmeter probes to ECM terminal No. 110 (Green wire) (EVAP control system pressure sensor signal) and ground.
- Check EVAP control system pressure sensor value at idle speed and note it. Establish and maintain the following conditions for at least one minute:
- Air conditioner switch: ON.
- Headlamp switch: ON.
- Rear window defogger switch: ON.
- Engine speed: About 3000 RPM.
- Gear position: Any position other than "P", "N" or "R".
Verify that EVAP control system pressure sensor value stays 0.1 volt less than the value at idle speed (measured previously) for at least one second. If NG is displayed, go to DIAGNOSTIC PROCEDURE .
