Code P2135 2009 Ford Fusion Description
The P2135 diagnostic trouble code (DTC) for a 2009 Ford Fusion indicates a problem with the Throttle/Pedal Position Sensor/Switch 'A'/'B' Voltage Correlation. This code is specifically related to the correlation between the throttle position sensor (TPS) and the pedal position sensor (PPS) in the vehicle's electronic throttle control system. The TPS and PPS work together to determine the position of the throttle pedal and how much air should be allowed into the engine for combustion.
Common Causes of P2135 2009 Ford Fusion
- Faulty throttle position sensor
- Faulty pedal position sensor
- Wiring or connector issues in the sensor circuit
- ECM malfunction or software glitch
- Environmental factors such as moisture or corrosion affecting sensor operation
Symptoms of P2135 2009 Ford Fusion
- Rough idling or stalling
- Hesitation or lack of response when accelerating
- Reduced fuel efficiency
- Check Engine Light illuminated
- Limited or erratic throttle response
How to Fix P2135 2009 Ford Fusion
- Perform a comprehensive diagnostic scan to confirm the P2135 code and identify the specific sensor causing the voltage correlation issue.
- Inspect the throttle and pedal position sensors, wiring, and connectors for any visible damage or corrosion.
- Test the sensors using a multimeter to check for proper voltage output and resistance values.
- Replace any faulty sensors or repair damaged wiring/connectors as needed.
- Clear the DTC and perform a test drive to ensure the issue has been resolved and the code does not reappear.
Cost to Fix P2135 2009 Ford Fusion
The typical repair costs for addressing a P2135 code on a 2009 Ford Fusion can range from $200 to $500, including parts and labor. However, the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. It's advisable to check local rates for a more precise estimate. Keep in mind that rates in metropolitan areas or at dealerships may be higher, while independent shops often charge less.

Frequently Asked Questions about P2135 2009 Ford Fusion Code
1. What does the OBDII code P2135 mean on a 2009 Ford Fusion?
P2135 indicates a voltage correlation issue between the throttle position sensor (TPS) "A" and "B," meaning the sensors are providing inconsistent readings to the engine control module (ECM).
2. What are the common symptoms of a P2135 code in a 2009 Ford Fusion?
Symptoms may include reduced engine power (limp mode), hesitation during acceleration, stalling, rough idling, or the check engine light illuminating.
3. What causes the P2135 code on a 2009 Ford Fusion?
Common causes include a faulty throttle position sensor, damaged wiring or connectors, carbon buildup in the throttle body, or a malfunctioning accelerator pedal position sensor.
4. Can I drive my 2009 Ford Fusion with a P2135 code?
It's not recommended to drive with this code for extended periods as it can lead to reduced performance, sudden loss of power, or unsafe driving conditions.
5. How do I diagnose a P2135 code on a 2009 Ford Fusion?
Start by checking the wiring and connectors for damage or corrosion, inspect the throttle body for carbon buildup, and test the throttle position and accelerator pedal sensors for proper voltage and signal output.
6. How do I fix the P2135 code on a 2009 Ford Fusion?
Common fixes include cleaning or replacing the throttle body, repairing damaged wiring or connectors, or replacing the throttle position sensor or accelerator pedal sensor if faulty.
7. Is a throttle body cleaning enough to fix the P2135 code?
In some cases, cleaning the throttle body can resolve the issue if carbon buildup is causing the sensors to send incorrect signals. However, other components may still need inspection or replacement.
8. How much does it cost to repair a P2135 code on a 2009 Ford Fusion?
The cost can vary depending on the repair. Replacing the throttle position sensor or accelerator pedal sensor typically costs between $150 and $400, including parts and labor.
9. What tools are needed to diagnose and repair the P2135 code on a 2009 Ford Fusion?
You may need an OBDII scanner, a multimeter to test voltage, basic hand tools, and throttle body cleaner if cleaning is required.
10. Can a software update fix the P2135 code on a 2009 Ford Fusion?
In rare cases, a reprogramming or update of the ECM may resolve the issue if it’s related to incorrect sensor interpretation. This should only be done after ruling out hardware issues.
