Kick Down Switch Circuit Intermittent/Erratic
The kick-down switch signal jumps or drops out intermittently. 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
- Wiring harness
Common causes
- High likelihood: Switch connector not fully seated
- Medium likelihood: Worn switch contacts
- Low likelihood: Connector with intermittent contact under vibration
Diagnostic notes
- The malfunction indicator lamp may illuminate
