Code P1120 2006 Ford Fusion Description

The Throttle Position Sensor (TPS) responds to the accelerator pedal movement. The TPS is a rotary potentiometer sensor that provides a signal to the Powertrain Control Module (PCM) that is linearly proportional to the throttle plate/shaft position. As the TPS is rotated by the throttle shaft, the following operating conditions are determined by the PCM:
• Closed throttle (includes idle or deceleration)
• Part throttle (includes cruise or moderate acceleration)
• Wide open throttle (includes maximum acceleration or de-choke on crank)
• Throttle angle rate

Frequently Asked Questions about P1120 2006 Ford Fusion Code

1. What does the OBDII code P1120 mean on a 2006 Ford Fusion?

P1120 indicates that the Throttle Position Sensor (TPS) is reporting a voltage outside the expected range, which can cause issues with engine performance.

2. What are the symptoms of code P1120 in a 2006 Ford Fusion?

Common symptoms include poor acceleration, engine stalling, reduced fuel efficiency, hesitation during throttle application, and the Check Engine Light being illuminated.

3. What causes the P1120 code in a 2006 Ford Fusion?

Potential causes include a faulty throttle position sensor, wiring issues such as damaged or corroded connectors, or problems with the vehicle's powertrain control module (PCM).

4. Can I drive my 2006 Ford Fusion with a P1120 code?

It is not recommended to drive with this code, as it can lead to unsafe driving conditions like reduced engine power or stalling.

5. How do I fix the P1120 code on a 2006 Ford Fusion?

Common fixes include replacing the throttle position sensor, repairing or replacing damaged wiring or connectors, and, if necessary, reprogramming or replacing the PCM.

6. How is the P1120 code diagnosed?

A mechanic will use a scan tool to confirm the code, inspect the TPS and its wiring for damage, and test the sensor's voltage readings to ensure they are within range.

7. How much does it cost to repair a P1120 code on a 2006 Ford Fusion?

The cost can range from $100 to $300, depending on whether the issue is a simple sensor replacement or additional wiring repairs are required.

8. Can a dirty throttle body cause the P1120 code?

While uncommon, a dirty or malfunctioning throttle body can sometimes trigger TPS-related codes if it interferes with proper sensor readings.

9. Does the P1120 code mean the throttle position sensor is completely broken?

Not necessarily. The sensor could be misaligned or experiencing intermittent faults due to wiring or connector issues.

10. How can I prevent the P1120 code from appearing in the future?

Regular maintenance, including inspecting and cleaning electrical connections and ensuring the throttle body is clean, can help prevent this code from reoccurring.
