Code P0122 2000 Ford F150 Description

The P0122 code for a 2000 Ford F150 indicates a Throttle Position Sensor (TPS) Circuit Low Input. The TPS is a vital component of the vehicle's fuel management system, as it helps the engine control unit (ECU) determine the right amount of air to mix with the fuel for combustion. When the ECU receives a low input signal from the TPS, it can lead to various performance issues and potentially cause long-term damage if left unaddressed.

Tech Notes for P0122 2000 Ford F150

The TP sensor circuit is monitored by the PCM for a low TP rotation angle (or voltage) input through the comprehensive component monitor (CCM). If during key ON engine OFF or key ON engine running the TP rotation angle (or voltage) changes below a minimum calibrated limit, the test fails.



Fault exhibits a symptom of limited power. A TP PID (TP VPID) reading less than 3.42% (0.17 volt) in key ON engine OFF, continuous memory or key ON engine running indicates a hard fault.

When is the Code Detected?

The Throttle Position Sensor (TPS) signal 1 circuit has reported an open or low voltage
