Vehicles with 2.0L engine
The acceleration control consists of the pedal and shaft assembly, accelerator cable and accelerator cable bracket.
| WARNING | Make sure surrounding components such as wiring, hoses, sound insulation and floor carpeting are not contacting the sliding inner cable or the accelerator pedal and shaft. Failure to follow these instructions may result in personal injury. |
The throttle is controlled by an accelerator cable attached to the accelerator pedal and shaft. The accelerator pedal and shaft should travel smoothly from the idle to the wide-open throttle positions. Hesitation on return or prevention of return to the idle position must not occur.
Vehicles with 2.5L, 3.0L or diesel engine
The accelerator pedal demand sensor provides an analogue voltage to the ECM which is proportional to the accelerator pedal position. A throttle position sensor provides a signal to the ECM which monitors throttle plate position.
After receiving these signals and monitoring the wheel speed signal output, coolant temperature, rotary switch status (automatic transmission) and inertia switch confirmation, the ECM then issues a throttle request signal. A motor within the throttle body rotates the throttle plate to a position which is relative to the position demanded.
- Verify the customer concern by operating the system.
- Visually inspect for obvious signs of mechanical or electrical damage.
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- If the concern is not visually evident, use a fault code reader to retrieve the fault codes before proceeding to «Symptom Chart»(ref-311866-S37660780642009040700000) .
