P0123 2000 Ford F150 Code - Throttle Position Circuit High Input
Quick Answer
The P0123 diagnostic trouble code (DTC) for a 2000 Ford F150 refers to a Throttle Position Circuit High Input. Common causes include Faulty TPS: The most common cause of the P0123 code is a malfunctioning throttle position sensor that is sending a high voltage signal to the ECM, Wiring Issues: Damaged or corroded wiring connecting the TPS to the ECM can lead to a high input signal, ECM Malfunction: A problem with the Engine Control Module can also cause the ECM to receive a high input signal from the TPS. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0123 2000 Ford F150 Description
The P0123 diagnostic trouble code (DTC) for a 2000 Ford F150 refers to a Throttle Position Circuit High Input. This code indicates that the Engine Control Module (ECM) has detected a higher than normal voltage coming from the throttle position sensor (TPS) circuit. The TPS is a crucial component that monitors the position of the throttle valve and sends this information to the ECM to adjust fuel delivery and ignition timing accordingly. When the ECM receives a high input signal from the TPS, it can lead to various performance issues and potentially affect the vehicle's drivability.
Common Causes of P0123 2000 Ford F150
- Faulty TPS: The most common cause of the P0123 code is a malfunctioning throttle position sensor that is sending a high voltage signal to the ECM.
- Wiring Issues: Damaged or corroded wiring connecting the TPS to the ECM can lead to a high input signal.
- ECM Malfunction: A problem with the Engine Control Module can also cause the ECM to receive a high input signal from the TPS.
- Throttle Body Issues: A dirty or faulty throttle body can affect the TPS readings, leading to a high input signal.
- Poor Electrical Ground: A poor electrical ground connection can cause voltage fluctuations in the TPS circuit, triggering the P0123 code.
Symptoms of P0123 2000 Ford F150
- Check Engine Light: The most common symptom associated with the P0123 code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Engine Power: The vehicle may experience a loss of power or sluggish acceleration due to the ECM going into failsafe mode.
- Erratic Idle: The engine may idle erratically or stall due to incorrect throttle position readings.
- Poor Fuel Economy: A malfunctioning TPS can lead to improper fuel delivery, resulting in decreased fuel efficiency.
- Harsh Shifting: In automatic transmission vehicles, the transmission may exhibit harsh shifting or hesitation due to incorrect throttle position readings.
How to Fix P0123 2000 Ford F150
- Diagnostic Scan: Use an OBD-II scanner to retrieve the trouble codes and confirm the presence of the P0123 code.
- TPS Inspection: Inspect the throttle position sensor for any signs of damage or wear. Replace the TPS if necessary.
- Check Wiring: Inspect the wiring harness connecting the TPS to the ECM for any damage or corrosion. Repair or replace as needed.
- Test ECM: Perform a thorough test of the Engine Control Module to ensure it is functioning correctly. Replace the ECM if deemed necessary.
- Clear Codes: Clear the trouble codes from the ECM's memory after completing the repair process to reset the system.
Cost to Fix P0123 2000 Ford F150
The typical repair costs for addressing a P0123 code on a 2000 Ford F150 can range from $100 to $300, depending on the specific cause of the issue. This estimate includes the cost of a new throttle position sensor (if required) and any necessary wiring repairs. Additionally, labor costs can vary between $80 and $150 per hour, with the total repair time typically taking around 1-2 hours. It's important to note that prices can vary based on location, the shop's labor rates, and the availability of parts. It's advisable to consult with a trusted mechanic or repair shop for a more accurate cost estimate based on your specific situation.
Tech Notes for P0123 2000 Ford F150
A TP PID (TP V PID) reading greater than 93% (4.65 volts) in key ON engine OFF, continuous memory or key ON engine running indicates a hard fault.
