P2135
Throttle/Pedal Position Sensor/Switch A/B Voltage Correlation
2012-2018 Ford Focus Electric Electric Motor
Critical SeverityPowertrainGeneric (SAE)
Description
The dual throttle position sensors are reporting conflicting values, indicating a fault.
Symptoms
- Limp mode
- Reduced power
- Check engine light
- Erratic throttle response
Common Causes
- Failed TPS (built into throttle body)
- Connector corrosion
- Intermittent wiring
- 5V reference circuit fault
Diagnostic Steps
- Check TPS sensor A and B voltages
- Verify 5V reference
- Wiggle test wiring
- Check connector pins
Repair Notes
Replace throttle body assembly (TPS is integrated). Check 5V reference shared with other sensors.
