Code P1120 2007 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

1. What does the OBDII code P1120 mean on a 2007 Ford Fusion?

P1120 indicates that the Throttle Position Sensor (TPS) on your 2007 Ford Fusion is sending a signal that is out of the expected range.

2. What are the common symptoms of a P1120 code in a 2007 Ford Fusion?

Symptoms may include poor acceleration, engine stalling, rough idling, hesitation during throttle input, or the activation of the Check Engine Light.

3. What causes the P1120 code to appear in a 2007 Ford Fusion?

Common causes include a faulty throttle position sensor, damaged wiring or connectors in the TPS circuit, or a malfunctioning throttle body.

4. Can I drive my 2007 Ford Fusion with a P1120 code?

While the car may still be drivable, itâ€™s not recommended as symptoms like stalling and poor acceleration could pose safety risks.

5. How do I diagnose the P1120 code on a 2007 Ford Fusion?

Diagnosis involves scanning for codes, inspecting the throttle position sensor and its wiring, checking for loose or corroded connectors, and testing the TPS voltage range with a multimeter.

6. How do I fix the P1120 code on a 2007 Ford Fusion?

Repairs may include replacing the throttle position sensor, repairing damaged wiring or connectors, or cleaning/replacing the throttle body if itâ€™s malfunctioning.

7. How much does it cost to fix a P1120 code on a 2007 Ford Fusion?

The cost depends on the specific repair, but replacing a throttle position sensor typically ranges between $100 and $300, including parts and labor.

8. What happens if I ignore the P1120 code on my 2007 Ford Fusion?

Ignoring this code can lead to worsening drivability issues, reduced fuel efficiency, and potential damage to other engine components over time.

9. Can a dirty throttle body cause the P1120 code on a 2007 Ford Fusion?

Yes, a dirty or carbon-clogged throttle body can interfere with the sensor's readings and trigger the P1120 code.

10. Do I need to reprogram the ECU after replacing the throttle position sensor for a P1120 code?

In most cases, the ECU will relearn the new TPS automatically, but some situations may require a manual reset or throttle relearn procedure using a scan tool.
