Wells 5S5051 Throttle Position Sensor TPS Replacement

The Wells 5S5051 is a direct-fit replacement Throttle Position Sensor (TPS) engineered to meet or exceed original equipment manufacturer specifications for performance and durability. Produced by Wells Vehicle Electronics — a trusted name in automotive electrical components for over 120 years — this sensor restores proper throttle response and engine management communication.

The Throttle Position Sensor monitors the angle of the throttle plate and sends a corresponding voltage signal to the Engine Control Module (ECM). The ECM uses this signal to precisely command the fuel, ignition, and transmission systems. A worn or failed TPS can cause hesitation, stalling, surging, rough idle, or a no-start condition, and may trigger a Check Engine Light (CEL), Service Engine Soon (SES), or Malfunction Indicator Lamp (MIL) with associated diagnostic trouble codes (P-codes).

Key Features:

• Designed and tested to meet or exceed OE fit, form, and function requirements
• Directly replaces GM OEM part numbers 25532800 and 25535420
• Cross-references: ACDelco 213-919, Delphi SS10431, BWD EC1097, SMP TH50, Wells TPS119
• Attaches directly to the throttle body for a straightforward installation
• Manufactured by Wells Vehicle Electronics (WVE), a leader in automotive electrical components
• Backed by a comprehensive factory warranty

The Wells 5S5051 is a reliable, cost-effective solution for restoring accurate throttle position feedback and eliminating common drivability complaints associated with a failing TPS.
