Code P2135 2008 Ford Fusion Description
The P2135 diagnostic trouble code (DTC) for a 2008 Ford Fusion indicates a problem with the throttle/pedal position sensor/switch 'A'/'B' voltage correlation. In simpler terms, this means that there is a discrepancy between the voltage signals coming from the throttle position sensor (TPS) and the accelerator pedal position sensor (APPS). These sensors play a crucial role in the operation of the electronic throttle control system, which regulates the engine's air intake and fuel delivery for optimal performance.
Common Causes of P2135 2008 Ford Fusion
- Faulty throttle position sensor (TPS)
- Faulty accelerator pedal position sensor (APPS)
- Wiring issues or poor connections between sensors and control module
- Electronic throttle control module malfunction
- Water intrusion or corrosion in sensor connectors
Symptoms of P2135 2008 Ford Fusion
- Hesitation or lack of response when pressing the accelerator pedal
- Sudden acceleration or surging while driving
- Engine stalling or rough idling
- Reduced power mode or limp mode activated
- Illumination of the check engine light
How to Fix P2135 2008 Ford Fusion
- Diagnose the issue using a scan tool to confirm the P2135 code and pinpoint the source of the problem.
- Inspect the throttle position sensor and accelerator pedal position sensor for any signs of damage or wear.
- Check the wiring harness and connectors for corrosion, damage, or poor connections.
- Replace the faulty sensor (TPS or APPS) if necessary and clear the code from the engine control module.
- Test drive the vehicle to ensure that the issue is resolved and that the throttle response is smooth and consistent.
Cost to Fix P2135 2008 Ford Fusion
The cost of repairing a P2135 code on a 2008 Ford Fusion can vary depending on the specific cause of the issue and the parts/labour rates in your area. Generally, replacing a throttle position sensor or accelerator pedal position sensor can cost between $100 and $300 for the part alone. Labour costs can range from $100 to $200, bringing the total repair cost to around $200 to $500. It's important to consult with a professional mechanic to get an accurate estimate based on your vehicle's specific needs and location.

Frequently Asked Questions about P2135 2008 Ford Fusion Code
1. What are the common symptoms of OBDII code P2135 on a 2008 Ford Fusion?
- Common symptoms include a lack of throttle response, reduced engine power, and the vehicle going into "limp mode."
2. What causes the Throttle/Pedal Position Sensor/Switch 'A'/'B' Voltage Correlation code P2135 on a 2008 Ford Fusion?
- The code is typically triggered by a faulty throttle position sensor, accelerator pedal position sensor, or wiring issues between the sensors and the engine control module.
3. How can I diagnose the P2135 code on my 2008 Ford Fusion?
- Diagnosing the code involves using a scan tool to check for the presence of P2135, testing the throttle position sensor and accelerator pedal position sensor voltages, and inspecting the sensor wiring for any damage.
4. Can I still drive my 2008 Ford Fusion with the P2135 code?
- It is not recommended to drive the vehicle with the P2135 code present, as it can lead to unsafe driving conditions and potential further damage to the engine or transmission.
5. How do I repair the Throttle/Pedal Position Sensor/Switch 'A'/'B' Voltage Correlation code on my 2008 Ford Fusion?
- The repair typically involves replacing the faulty throttle position sensor, accelerator pedal position sensor, or repairing any damaged wiring connections to resolve the issue.
6. Are there any DIY tips for fixing the P2135 code on a 2008 Ford Fusion?
- While diagnosing and repairing the P2135 code may require some technical expertise, DIY enthusiasts can follow online guides and videos to understand the process and attempt the repair themselves.
7. Is it expensive to fix the Throttle/Pedal Position Sensor/Switch 'A'/'B' Voltage Correlation code on a 2008 Ford Fusion?
- The cost of fixing the P2135 code can vary depending on the specific cause of the issue, but it usually involves replacing sensors or repairing wiring, which may not be overly expensive if done promptly.
8. Will resetting the OBDII code P2135 on my 2008 Ford Fusion make it go away permanently?
- Resetting the code may temporarily turn off the check engine light, but if the underlying issue causing the P2135 code is not addressed, the code is likely to return.
9. Can a bad throttle body cause the P2135 code on a 2008 Ford Fusion?
- While a faulty throttle body can sometimes cause similar symptoms, the P2135 code specifically relates to issues with the throttle and pedal position sensors, rather than the throttle body itself.
10. How long does it take to repair the P2135 code on a 2008 Ford Fusion?
- The repair time can vary based on the exact cause of the P2135 code, but a skilled mechanic can typically diagnose and fix the issue within a few hours to a day.
