Throttle Position Sensor Disagreement Between Sensors

What this code means

The PCM has detected a disagreement between the two throttle position sensors on the electronic throttle body. Modern Ford vehicles use dual TP sensors for safety — if they disagree, the PCM limits engine power.

Symptoms

• Check Engine Light
• Reduced engine power (limp mode)
• Throttle response limited
• Engine may idle only

Common causes

• Faulty throttle body (integrated TP sensors)
• Wiring issue to one of the TP sensors
• Corroded TP sensor connector
• Carbon buildup affecting throttle plate position

Diagnostic steps

1. Compare TP sensor 1 and TP sensor 2 readings on scan tool
2. Check that both sensors track together through full range
3. Inspect throttle body connector for corrosion
4. Clean throttle body
5. Check wiring harness for damage

Repair notes

Clean throttle body. If sensors disagree, replace throttle body (sensors not separately serviceable on most models).
