Code P2135 Lincoln Description
The P2135 diagnostic trouble code for Lincoln vehicles indicates an issue with the throttle or pedal position sensor/switch 'A'/'B' voltage correlation. Essentially, this code is triggered when the Engine Control Module (ECM) detects a discrepancy between the voltage signals from the throttle position sensor (TPS) and the accelerator pedal position sensor (APPS). The TPS monitors the position of the throttle valve, while the APPS detects the position of the accelerator pedal.
Common Causes of P2135 Lincoln
- Faulty throttle position sensor.
- Malfunctioning accelerator pedal position sensor.
- Wiring or connector issues in the sensor circuit.
- Corrosion or dirt buildup affecting sensor performance.
- ECM software or hardware malfunction.
Symptoms of P2135 Lincoln
- Poor acceleration or lack of response when pressing the accelerator pedal.
- Engine stalling or rough idling.
- Reduced fuel efficiency.
- Engine hesitation or jerking during acceleration.
- Illumination of the Check Engine Light on the dashboard.
How to Fix P2135 Lincoln
- Diagnose the issue by using a scan tool to retrieve the trouble codes and perform a thorough inspection of the throttle and pedal position sensors.
- Check the wiring and connectors for any signs of damage, corrosion, or loose connections. Repair or replace as needed.
- Test the throttle and pedal position sensors for proper voltage output and signal correlation. Replace any faulty sensors.
- Clear the trouble codes from the ECM and reset the system to see if the issue is resolved.
- Test drive the vehicle to ensure that the symptoms associated with the P2135 code have been eliminated.
Cost to Fix P2135 Lincoln
The typical repair costs for addressing a P2135 diagnostic trouble code can vary depending on the specific cause of the issue and the labor rates at the auto repair shop. Generally, replacing a faulty throttle or pedal position sensor can cost between $150 to $300, including parts and labor. However, additional costs may be incurred if wiring repairs or ECM reprogramming are necessary. It is advisable to consult with a professional mechanic to get an accurate estimate based on the specific circumstances of the vehicle. Labor rates at auto repair shops typically range from $80 to $150 per hour, but can vary based on location and other factors.

What are the common symptoms of code P2135 in a Lincoln?
Symptoms may include reduced engine power, hesitation during acceleration, the Check Engine Light, or the vehicle entering "limp mode."
What causes the P2135 code to appear?
Common causes include a faulty throttle position sensor, damaged wiring or connectors, or issues with the electronic throttle body.
Can I drive my Lincoln with the P2135 code?
Driving with this code is not recommended, as the vehicle may experience sudden power loss or enter "limp mode," posing safety risks.
How do I diagnose the P2135 code in my Lincoln?
Diagnosis involves inspecting the throttle position sensors, wiring, and connectors for damage, testing sensor output, and checking for proper voltage correlation.
What tools do I need to troubleshoot P2135 in a Lincoln?
You’ll need an OBDII scan tool, multimeter, and possibly wiring repair tools to test and fix the issue.
How do you fix a P2135 code in a Lincoln?
Repairs may include replacing the throttle position sensor, repairing damaged wiring or connectors, or replacing the electronic throttle body.
Does the P2135 code require reprogramming after repairs?
In some cases, a throttle body relearn procedure or ECM reprogramming may be necessary after replacing components.
How much does it cost to fix the P2135 code on a Lincoln?
Repair costs vary but may range from $100 to $500, depending on whether the throttle position sensor or throttle body needs replacement.
Can a dirty throttle body trigger the P2135 code?
