Diagnostic boundary
A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.
Do not replace modules before checking sensor B wiring; redundant throttle circuits are sensitive to small signal faults.
Useful checks before replacing parts
- Check for short-to-voltage, open ground, poor connector contact, and a sensor B signal stuck high.
- Compare sensor B with sensor A, commanded throttle angle, and pedal position data.
- Inspect harness routing near the throttle body and pedal assembly for chafing, water intrusion, or prior repairs.
