Ford Escape 2.0 Throttle Position Sensor (TPS), 2001–2004, 988F9B989BB

Ford Escape 2.0 Throttle Position Sensor (TPS), 2001–2004, part no. 988F9B989BB is a component of the engine management system. It records the throttle position or opening angle and converts it into an electrical signal sent to the engine control unit (ECU).

Using the sensor signal, the ECU adjusts engine operation to suit driving conditions and driver input. If the sensor does not operate accurately, the signal sent to the ECU may be incorrect, affecting acceleration and engine stability.

Part number 988F9B989BB has the reference replacement number YS4Z9B989BB. Parts catalogs also list both numbers in the Ford throttle position sensor category. However, check the VIN, the number on the old sensor, and the engine configuration to confirm compatibility with the 2001–2004 Ford Escape 2.0.
