Special tools, testers and auxiliary items required
-
Multimeter.
-
Wiring diagram.
Test requirements
-
Fuse SB38 OK.
-
The ignition switched off.
NOTE: Voltage for the Evaporative Emission (EVAP) Canister Purge Regulator Valve N80 is supplied by the Power Supply Relay (terminal 30,
B+) J317.
Test procedure
-
Perform a preliminary check to verify the customers complaint. See: Computers and Control Systems/Testing and Inspection/Scan Tool Testing
and Procedures/Preliminary Check
Start diagnosis
-
Disconnect the Evaporative Emission (EVAP) Canister Purge Regulator Valve N80 electrical harness connector.
Checking internal resistance
-
Using a Multimeter, check the resistance between terminals 1 and 2 of the Evaporative Emission (EVAP) Canister Purge Regulator Valve N80.
Specified value: 22.0 to 30.0 ohms.
If the specified value was not obtained:
-
Replace the Evaporative Emission (EVAP) Canister Purge Regulator Valve N80.
If the specification is obtained:
Checking voltage supply
-
Using a Multimeter, check the electrical harness connector terminal 1 to Ground (GND) for voltage.
-
Operate the starter briefly.
Specified value: battery voltage.
If the specified value was not obtained:
-
Check the wiring connection from the Evaporative Emission (EVAP) Canister Purge Regulator Valve N80 electrical harness connector terminal 1
to the Power Supply Relay (terminal 30, B+) J317 terminal 87 for an open circuit a short circuit to Battery positive (+)or to Ground (GND).
-
Check the electrical harness connector for damage, corrosion, loose or broken terminals.
-
If necessary, repair the wiring connection.
If the specified value was obtained:
Check Ground (GND) activation
If the manufacturers test box is being used. Perform the following step.
-
Install the test box.
