Overall Function Check

Use this procedure to check the overall monitoring function of the EVAP control system purge flow monitoring. During this check, a 1st trip DTC might not be confirmed.

Without CONSULT
(1) Lift up drive wheels.
(2) Start engine and warm it up to normal operating temperature.
(3) Turn ignition switch "OFF", wait at least 5 seconds.
(4) Start engine and wait at least 70 seconds.
(5) Set voltmeter probes to ECM terminals 62 (EVAP control system pressure sensor signal) and ground.
(6) Check EVAP control system pressure sensor value at idle speed and note it.
(7) Establish and maintain the following conditions for at least 1 minute.
Air conditioner switch: ON
Steering wheel: Fully turned
Headlamp switch: ON
ear window defogger switch: ON
Engine speed: Approx. 3,000 rpm
Gear position:
M/T models
Any position other than "Neutral" or "Reverse"
A/T models
Any position other than "P", "N" or "R"
Verity that EVAP control system pressure sensor value stays 0.1V less than the value at idle speed (measured at step 6) for at least 1 second.
