P1125 1997 FORD F150 Possible Causes
- Faulty throttle position sensor
- Throttle position sensor wiring harness is open or short-circuited
- Poor electrical connection in throttle position sensor circuit
How to Fix P1125 Code on 1997 FORD F150?
Start by checking the “possible causes” listed above. Visually inspect the corresponding wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
What Does It Mean?
The TP sensor circuit is monitored by the PCM for a sudden change in TP rotation angle input (or voltage) through the comprehensive component monitor (CCM). If during the last 80 key-on engine warm-up cycles, the PCM detects a TP rotation angle (or voltage) change beyond the minimum or maximum calibrated limit, a continuous diagnostic trouble code (DTC) is stored.
When Is the Code Detected?
The Engine Control Module (ECM) detected the Throttle Position (TP) sensor voltage extending above or below calibrated limits
Possible Symptoms
Check engine light illuminated (or service engine soon warning light)
P1125 1997 FORD F150 Meaning
The throttle position sensor (TPS) responds to 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 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 crank flare)
• Throttle angle rate
