The accelerator sensor monitors the road conditions. It sends a signal to the ECM, the ECM determines if a possible
misfire condition exists.
Removal & Installation
1. Disconnect the negative battery cable.
2. Disconnect the accelerator sensor electrical con-nector.
3. Remove the accelerator sensor (1).
4. Installation is in the reverse order of removal.
Manifold Absolute Pressure Sensor - 1.6L
Description
The Manifold Absolute Pressure (MAP) sensor, is mounted to the front of the engine on the intake manifold.
Operation
The MAP sensor monitors the pressure in the intake manifold. The pressure in the manifold moves a diaphragm
connected to resistors which alter their resistance values. The output voltage of the MAP sensor signals the ECM
about the pressure in the intake manifold.
Removal & Installation
1. Disconnect the negative battery cable.

Vapor Canister 1.6L & 1.8L & 2.0L
Description
The vapor canister is located on the left side of the core support and is filled with activated carbon granules.
Operation
The vapor canister is filled with activated carbon granules. Fuel tank vapors are vented into the canister where they
are absorbed by the activated carbon granules. The canister temporarily holds the fuel vapors until intake manifold
vacuum draws them into the cylinder chamber. The Engine Control Module (ECM) purges the canister through the
pulse-width modulated canister control valve. The ECM purges the canister at predetermined intervals and engine
conditions.
Removal & Installation
1. Raise and support the vehicle.

Description
The rear axle utilizes an independent design. This suspension system incorporates a separate wheel knuckle for
each wheel and allows the wheels to react to road imperfections independent of each other. This independent action
offers improved isolation from the effects of jounce and rebound.
The rear axle consists of the following components:
•Wheel Hub
• Wheel Studs
• Wheel Bearing
• Rear Trailing Arm
For further information on the rear axle assembly see Rear Suspension Description & Operation in Section 10 Sus-
pension.
Operation
The rear axle utilizes a sealed wheel bearing housed in the rear knuckle assembly. Rear Axle
