GENERAL SPECIFICATIONS
The steering system consists of the following components
- Power steering pump (includes fuel efficient power steering (FEPS) solenoid/actuator)
- Steering gear
- Power steering lines
- Fluid reservoir
- Fluid cooler
- Steering linkage
- Steering wheel
- Steering column
- Steering column shaft
- Steering column switches
- Steering effort control module (SECM)
- Steering wheel rotation sensor
For information on the power steering pump, steering gear, power steering lines, fluid reservoir, fluid cooler and inner tie-rod refer to POWER STEERING article.
For information on the steering wheel and steering column, refer to STEERING COLUMN article.
For information on the steering column switches, refer to STEERING COLUMN SWITCHES article.
The power steering system transfers driver inputs at the steering wheel to the front wheels of the vehicle. The steering column, hydraulic system and linkages that transfer these inputs make up the steering system. Gearing and hydraulic assist are used to significantly reduce steering efforts.
The FEPS system provides improved fuel economy by reducing the fluid flow from the power steering pump when it is not needed.
