Kick Down Switch Circuit Range/Performance
The kick-down switch state is implausible against accelerator pedal position. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
Affected components
- Kickdown switch
- Accelerator pedal
Common causes
- Medium likelihood: Switch trip point drift
- Medium likelihood: Accelerator pedal travel out of spec
- Low likelihood: Sensor element aged beyond calibration window
Diagnostic notes
- The malfunction indicator lamp may illuminate
