The fuel delivery system is enabled when it reaches the following conditions:
•Turn the ignition switch ON (engine off), the fuel delivery system is enabled for 3-6 seconds.
• The Engine Control Module (ECM) receives a Crankshaft Position (CKP) sensor signal.
The fuel injectors are a solenoid-operated valve that meter fuel flow to each cylinder. The fuel injectors are opened
and closed constantly during engine operation. The amount of fuel is controlled by the length of time the fuel injector
is held open. The fuel injectors are powered by a 12 V source and are controlled through the ground side of the
circuit by the ECM.
The fuel pump operation is defined in the fuel system control strategy and is controlled by the ECM.

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.

Operation
The primary purpose of a cooling system is to maintain engine temperature in a range that will provide satisfactory
engine performance and emission levels under all expected driving conditions. It also provides hot coolant for heater
performance and cooling for automatic transmission oil. This is done by transferring heat from engine metal to cool-
ant, moving the heated coolant to the radiator, and then transferring the heat to the ambient air. Engine Coolant Flow Diagram - 1.6L & 1.8L & 2.0L

Description
The DP0 automatic transaxle is a four-speed transaxle that is a conventional hydraulic/mechanical transaxle assem-
bly with an integral differential, and is controlled with adaptive electronic controls and monitors. The hydraulic system
of the transaxle consists of the transaxle fluid, fluid passages, hydraulic valves, fluid pump, and various line pressure
control components.
The Transaxle Control Module (TCM) is the heart of the electronic control system and relies on information from
various direct and indirect inputs (sensors, switches, etc.) to determine driver demand and vehicle operating condi-
tions. With this information, the ECM/TCM can calculate and perform timely and quality shifts through various output
or control devices.
The TCM also performs certain self-diagnostic functions and provides comprehensive information (sensor data,
DTCs, etc.) which is helpful in proper diagnosis and repair. This information can be viewed with the X-431 scan tool.
