CANISTER-VAPOR
OPERATION
The Evaporative System Vapor Canister is filled with granules of an activated carbon mixture. Fuel vapors entering the EVAP canister is absorbed by the charcoal granules.
Fuel tank pressure vents into the EVAP canister. Fuel vapors are temporarily held in the canister until they can be drawn into the intake manifold. The duty cycle EVAP canister purge solenoid allows the EVAP canister to be purged at predetermined times and at certain engine operating conditions.
REMOVAL
The EVAP (Evaporative System Vapor) canister (5) is located in the left-rear quarter-panel behind the left-rear tire. The ESIM (Emission System Integrity Monitor) switch (3) is attached to the EVAP canister.
The EVAP canister and ESIM switch are replaced together as one assembly.
1. Raise and support vehicle.
2. Remove left-rear tire.
3. Remove plastic splash shield at rear of left-rear tire.
4. Disconnect electrical connector at pump ESIM switch.
5. Carefully remove vapor/vacuum hoses at EVAP canister and ESIM switch.
6. Remove three canister bracket-to-body nuts (1) and (2).
7. Separate canister from mounting bracket by removing two canister-to-bracket nuts at front of canister (4). The opposite end of canister is equipped with two alignment pins. Remove canister from support bracket by pulling these two pins from the two rubber grommets.
INSTALLATION
The EVAP canister and ESIM switch are replaced together as one assembly.
1. Position canister (5) into mounting bracket (6). Install and tighten two canister-to-mounting bracket nuts (4).
2. Position canister/switch/bracket assembly to body. Install and tighten three mounting bracket-to-body nuts (1) and (2).
3. Carefully install vapor/vacuum lines to EVAP canister and ESIM switch. The vapor/vacuum lines and hoses must be firmly connected. Check the vapor/vacuum lines at the EVAP canister, ESIM switch and EVAP canister purge solenoid for damage or leaks. If a leak is present, a Diagnostic Trouble Code (DTC) may be set.
