Throttle Position Sensor

WARNING: This page does not describe the selected car, but rather 31 other vehicles, including the 2003 Mercury Sable, 2003 Mercury Mountaineer, 2003 Mercury Marauder, 2003 Mercury Grand Marquis, and 2003 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.

Throttle Position (TP) sensor is a rotary potentiometer sensor that provides a signal to PCM that is linearly proportional to throttle plate/shaft position. TP sensor housing has a 3-blade electrical connector that may be gold plated. The gold plating increases corrosion resistance on terminals and increases connector durability. TP sensor is mounted on throttle body and has 4 operating conditions: closed throttle (idle or deceleration), part throttle (cruise or moderate acceleration), wide open throttle (includes maximum acceleration or de-choke on crank), and throttle angle rate. TP sensor signal affects air/fuel ratio, injector timing, idle speed, EGR flow and ignition timing.
