Vent Control Solenoid

If you wish to substitute the evaporative emission canister purge solenoid valve, remove the cleaner assembly of the air from the studs and put it aside. Remove the electrical connector from the evaporative emission (EVAP) canister purge valve, and the eviction canister purge valve tube to the Intake Manifold using the plastic collar quick connect fitting service. Next, use the plastic collar quick connect fitting service to disconnect the chassis evap vapor line from the evap canister purge valve. Unscrew the bolt from the evap canister purge valve bracket and remove the evap canister purge valve and the bracket from the car. Pull the evap canister purge valve away from the bracket and examine the ports for carbon discharge; if for some unknown reason there are loose carbon and it is found after going through the evaluation process, replace the evap canister and related components with it to get rid of the carbon particles. For installation, this is the bracket evap evap canister purge valve mounted to the bracket when the assembly with the bracket is placed on the Cylinder Head following the fastener notice. Fasten the evap canister purge valve bracket bolt with 18 n.m (13 lb ft). Connect the evap canister purge valve tube to the Intake Manifold using the plastic collar quick connect fitting service and connect the chassis evap vapor line to the evap canister purge valve. Lastly, re-connect the evap canister purge valve electrical connector and replace the air cleaner assembly to the studs.

Install the EVAP canister purge valve bracket bolt and tighten it to 18 Nm (13 lb ft).

Replace the EVAP canister and any necessary components to eliminate the carbon particles.

Detach the EVAP canister purge valve from the bracket and inspect for carbon release in the valve ports; if loose carbon is found, replace the EVAP canister and any necessary components to eliminate the carbon particles.
