Inspection and Verification
- Verify the customer's concern by operating the acceleration control system to duplicate the condition.
- Inspect to determine if any of the following mechanical concerns apply. Visual Inspection Chart VISUAL INSPECTION CHART Mechanical Damaged accelerator pedal and shaft Damaged linkage Damaged accelerator cable High engine idle speed Damaged Throttle Body (TB)
- If the inspection reveals an obvious concern that can be readily identified, repair it as required.
- If the concern remains after the inspection, determine the symptom(s) and go to the «SYMPTOM CHART»(ref-365435-S20305776442010070700000) .
Symptom Chart
| Condition | Possible Sources | Action |
|---|---|---|
| Excessive effort is needed to depress the accelerator pedal and shaft | Accelerator cable binding | INSTALL a new accelerator cable. |
| Worn or damaged Throttle Body (TB) | INSTALL a new throttle body. REFER to FUEL CHARGING AND CONTROLS - 2.3L (2.3L) or FUEL CHARGING AND CONTROLS - 4.0L SOHC (4.0L). | |
| The accelerator pedal and shaft feels rough or raspy | Frayed or binding accelerator cable | INSTALL a new accelerator cable. |
| Worn or damaged TB | INSTALL a new TB . REFER to FUEL CHARGING AND CONTROLS - 2.3L (2.3L) or FUEL CHARGING AND CONTROLS - 4.0L SOHC (4.0L). | |
| The accelerator pedal and shaft binds or sticks | Kinked accelerator cable | INSTALL a new accelerator cable. |
| Foreign material caught in accelerator pedal linkage | CHECK the accelerator pedal linkage. | |
| Worn or damaged TB | INSTALL a new TB . REFER to FUEL CHARGING AND CONTROLS - 2.3L (2.3L) or FUEL CHARGING AND CONTROLS - 4.0L SOHC (4.0L). | |
| The engine idle speed is high | Kinked accelerator cable | INSTALL a new accelerator cable. |
| Foreign material caught in accelerator pedal linkage Accelerator pedal caught under mispositioned floor mat | CHECK the accelerator pedal linkage. | |
| Incorrect engine idle speed | REFER to the INTRODUCTION - GASOLINE MODELS for diagnosis and testing of the idle control system. |
