Code P1125 2001 Ford F150 Description

The P1125 code for a 2001 Ford F150 indicates an intermittent issue with the throttle position sensor (TPS). The TPS is a crucial component of the vehicle's fuel injection system, as it monitors the position of the throttle valve and sends this information to the engine control module (ECM). This data is used to determine the appropriate fuel delivery and ignition timing for optimal engine performance. An intermittent problem with the TPS can lead to erratic engine operation, poor fuel economy, and potential drivability issues. If not addressed, it can cause further damage to the engine and emission control systems.

Tech Notes for P1125 2001 Ford F150

The TP sensor circuit is monitored by the PCM for sudden TP rotation angle (or voltage) input change through the comprehensive component monitor (CCM). If during the last 80 warm-up cycles in key ON engine running the PCM detects a TP rotation angle (or voltage) changes beyond the minimum or maximum calibrated limit, a continuous diagnostic trouble code (DTC) is stored.

When is the Code Detected?

Engine Control Module (ECM) detected the Thottle Position (TP) sensor voltage extended above or below calibrated limits
