Throttle Position Sensor — Part Numbers 2C0858850000 / 2C0858850000 Restore accurate throttle feedback to the engine control unit with a directfit throttle position sensor (TPS) specified by part numbers 2C0858850000 and 2C0858850000. This sensor measures the throttle plate position and supplies the ECU with the precise signal it needs for smooth idle, consistent acceleration, and reliable drivability. Key benefits Restores throttle response and engine performance by providing an accurate position signal to the ECU. Eliminates common drivability issues caused by a failing TPS, including hesitation, surging, poor idle, and unexpected stalling. Simple swapin replacement reduces time and avoids the need for modifications or reprogramming when installed on compatible vehicles. Improves fuel management and throttle control, helping maintain expected fuel economy and emissions behavior. Key attributes Functionality: Detects throttle plate angle and outputs the corresponding electrical signal to the vehicle's engine control system for precise air/fuel and ignition control. Compatibility: Identified by part numbers 2C0858850000 and 2C0858850000; intended as a replacement for applications specified to use these part numbers. Fit and form: Compact, directreplacement design intended to match OEM mounting points and electrical connector pinout for straightforward installation. Durability and performance: Engineered for accurate, repeatable position sensing under normal operating conditions to maintain consistent engine management and drivability. Use cases and applications a worn or failed TPS to resolve symptoms such as rough idle, throttle hesitation, or checkengine codes related to throttle position or sensor circuit faults. Include as part of routine throttle body service or engine tuneup to ensure the throttle control system is operating within specification. Use during diagnostics and when troubleshooting driveability issues to verify correct throttle position feedback to the ECU. Installation notes Intended as a directfit replacement for systems that list part number 2C0858850000 / 2C0858850000. Confirm vehicle parts compatibility using the vehicle's VIN or parts catalog prior to installation. After installation, follow manufacturerrecommended procedures for throttle adaptation or relearn if required by the vehicle's engine control system. this throttle position sensor by part number 2C0858850000 / 2C0858850000 when you need a reliable, accurate replacement to restore throttle feedback and improve engine response.
