Canister Control Valve 1.6L & 1.8L & 2.0L
Description
This vehicle uses a pulse-width modulated canister control valve. The canister control valve regulates the rate of
vapor flow from the vapor canister to the throttle body. The Engine Control Module (ECM) controls the frequency at
which the canister control valve operates in order to accommodate the vapor volume for each cylinder.
Operation
The canister control valve is installed near of the engine air filter. The Engine Control Module (ECM) controls the
opening and closing of the canister control valve. When the ECM relay is energized, the canister control valve
switches from closed to open.
Removal & Installation
1. Disconnect the negative battery cable.
2. Disconnect the canister control valve electrical con-nector.
3. Disconnect the lines from canister control valve (1).
4. Remove canister control valve (1) from the bracket.
5. Installation is in the reverse order of removal.
Canister Control Solenoid Valve 2.4L
Description
The canister control valve is located near of the engine air filter.
Operation
The Engine Control Module (ECM) controls the opening and closing of the canister control valve. When the ECM
relay is energized, the canister control valve switches from closed to open. The ECM uses a pulse-width modulated
canister control valve to regulates the rate of vapor flow from the vapor canister to the throttle body. The ECM con-

•Fuel pressure at idle: 320-350 kPa (3.2 - 3.5 bar)
3. If engine runs, but pressure is below minimum pressure, check the following: a. Check for a kinked fuel supply line between the fuel rail and the fuel pump, repair if necessary.
b. Check the fuel filter for blockage, and replace the fuel filter if necessary (See Fuel Filter Removal & Installa-
tion in Section 04 Fuel Delivery).
c. Check the fuel pump, and replace if necessary (See Fuel Pump Removal & Installation in Section 04 Fuel
Delivery).
4. If operating pressure is above the maximum pressure, the electric fuel pump is OK, but fuel pressure regulator is defective. Replace the fuel pressure regulator (See Fuel Pump Removal & Installation in Section 04 Fuel
Delivery).
NOTE:
• The 1.6L & 1.8L & 2.0L fuel pressure regulator is integrated into the fuel pump assembly and is not serviced
separately.
• The 2.4L fuel pressure regulator is connected to the fuel rail, and is serviced separately.
5. Install the protective cap to the service test port pressure fitting (1) on the fuel rail.
Observe the following fuel pressures when testing:
FUEL PRESSURE - 1.6L & 1.8L & 2.0L
Key On 400 kPa (4.0 bar)
Engine Idle 400-420 kPa (4.0 - 4.2 bar)
Key Off 380 kPa (3.8 bar) in 10 minutes
FUEL PRESSURE - 2.4L
Key On 329 kPa (3.29 bar)
Engine Idle 320-350 kPa (3.2 - 3.5 bar)
Key Off 350 kPa (3.5 bar) in 10 minutes

Fuel Pressure Relief Procedure
Description
WARNING!
Fuel in the fuel system remains under high pressure, even when the engine is not running. Before servicing or
disconnecting any of the fuel lines or fuel system components, the fuel system pressure must be relieved to
prevent accidental spraying of fuel. Failure to follow these instructions may result in serious personal injury or
death.
Perform the following procedure to relieve fuel pressure from the fuel system:1. Remove the cover of the front fuse and relay box.
2. Identify and remove the fuel pump relay from the front fuse and relay box.
3. Start and run engine until it stalls.
4. Attempt to restart engine until it will no longer run.
5. Turn the ignition key to the OFF position.
Fuel Pump
Description
The fuel pump assembly contains the fuel pump motor and fuel level sensor.
Operation
The Engine Control Module (ECM) activates the fuel pump relay for several seconds after the ignition switch is
turned ON. When the relay is activated, it provides voltage to the fuel pump. When the ECM receives an engine
speed signal from the Crankshaft Position (CKP) sensor and a signal from the Immobilizer control module, the ECM
will energize the fuel pump relay.
NOTE :
• The electric fuel pump has different flow ratings based on engine requirements
• For service, the part number of the replacement fuel pump must be the equivalent of the original fuel pump
• Do not operate the fuel pump dry, this will damage the fuel pump
• Keep the fuel tank and pipeline clean, and replace the fuel filter if the fuel pump is replaced
Removal & Installation
WARNING!
Release fuel system pressure before servicing fuel system components. Service vehicles in well-ventilated areas
and avoid ignition sources. Never smoke while servicing the vehicle. This may result in personal injury or death.
NOTE :
The following special tool is required to perform the repair procedure:
•CH-20032 - Fuel Pump Remover
1. Release the fuel system pressure (See Fuel Pressure Relief Procedure in Section 04 Fuel Delivery).
2. Disconnect the negative battery cable.
3. Remove the rear seat cushion.
