Wells 5S5127 Throttle Position Sensor 3-Terminal Blade Connector

The Wells 5S5127 is a direct-fit, throttle body-mounted Throttle Position Sensor (TPS) engineered to meet or exceed original equipment manufacturer specifications for fit, form, and function. Designed for Ford applications spanning model years 2000–2011, this sensor delivers reliable throttle position data to keep your engine management system operating at peak efficiency.

The Throttle Position Sensor monitors the angle of the throttle blade within the throttle body and transmits a voltage signal to the Engine Control Module (ECM). The ECM uses this data to precisely control fuel delivery, ignition timing, and transmission shift points—ensuring smooth acceleration and optimal performance.

Key Features:

• 3-Terminal blade connector with rectangular, female connector housing for a secure OE-style fit
• Throttle body mounted design for straightforward installation
• Mounting hardware included for a complete, hassle-free replacement
• Constructed from durable plastic material built to withstand underhood heat and vibration
• Engineered to meet or exceed OE specifications for performance and longevity

Common Symptoms of a Failing TPS:

• Hesitation or stumble during acceleration
• Erratic or harsh transmission shifting
• Illuminated check engine light
• Increased emissions or failed emissions test
