Code P0122 2006 Ford Fusion Description
The P0122 diagnostic trouble code (DTC) for a 2006 Ford Fusion indicates an issue with the Throttle/Pedal Position Sensor 'A' Circuit, specifically a low input signal. The throttle position sensor (TPS) is a crucial component that monitors the position of the throttle valve in the engine. It provides feedback to the engine control module (ECM) to adjust the air-fuel mixture and ignition timing for optimal performance. When the TPS 'A' circuit registers a low input signal, it means that the voltage signal from the sensor is below the expected range, indicating a potential problem with the sensor or its wiring.
Common Causes of P0122 2006 Ford Fusion
- Faulty throttle position sensor
- Damaged wiring or connectors in the TPS circuit
- Corroded or dirty sensor
- Malfunctioning ECM
- Issues with the throttle body
Symptoms of P0122 2006 Ford Fusion
- Reduced engine performance
- Poor fuel efficiency
- Hesitation or stalling during acceleration
- Rough idling
- Limp mode activation
How to Fix P0122 2006 Ford Fusion
- Begin by diagnosing the TPS using a scan tool to confirm the P0122 code and check for any other related codes.
- Inspect the wiring and connectors in the TPS circuit for any damage, corrosion, or loose connections.
- Test the throttle position sensor using a multimeter to verify its functionality and voltage output.
- Clean the throttle body and sensor to remove any dirt or debris that could be affecting its performance.
- If necessary, replace the throttle position sensor or repair any damaged wiring or connectors in the circuit.
Cost to Fix P0122 2006 Ford Fusion
The cost of repairing a P0122 code on a 2006 Ford Fusion can vary depending on the specific cause of the issue.

What are some common symptoms of the P0122 code?
Common symptoms include poor acceleration, reduced engine power, the check engine light being illuminated, and possibly erratic engine behavior.
What could cause the P0122 code to trigger?
Causes can include a faulty throttle position sensor, damaged wiring or connectors, issues with the engine control module (ECM), or a dirty throttle body.
How can I diagnose the P0122 code?
Start by visually inspecting the throttle position sensor and its wiring for damage or corrosion. Use a multimeter to check the sensor's voltage output and compare it to manufacturer specifications.
What repairs are typically needed for a P0122 code?
Repairs may involve replacing the throttle position sensor, repairing or replacing damaged wiring or connectors, or cleaning the throttle body if it is dirty.
Can I drive my 2006 Ford Fusion with a P0122 code?
It is not recommended to drive the vehicle extensively with this code, as it may lead to reduced engine performance and could potentially cause further damage.
How can I clear the P0122 code from the vehicle's computer?
You can clear the code using an OBDII scanner, or by disconnecting the battery for a few minutes, but it’s essential to solve the underlying issue first to prevent the code from returning.
Will the P0122 code affect fuel economy?
Yes, a malfunctioning throttle position sensor can negatively impact fuel economy due to improper air-fuel mixture adjustments by the engine control unit.
Is it safe to replace the throttle position sensor myself?
If you have basic automotive repair skills and tools, you can replace the throttle position sensor yourself, but ensure you follow safety protocols and verify the issue afterward.
