Key Features

FAQ

Service

The Throttle Position Sensor (TPS) 9950634 / TPS4260 is a key engine management component designed to accurately detect throttle valve movement and provide real-time position feedback to the vehicle’s ECU. Installed on the throttle body, this sensor helps the engine control system adjust fuel injection and ignition timing based on driving conditions, ensuring smoother throttle response and stable engine operation.

Designed as a replacement solution for selected Fiat, Alfa Romeo, and Lancia applications, this TPS sensor offers reliable signal output, accurate throttle monitoring, and consistent performance for automotive repair and aftermarket applications.

Based on the received signal, the ECU calculates the appropriate fuel delivery and ignition timing to maintain efficient combustion. A properly functioning TPS helps improve:

Smooth acceleration response
Stable engine idle performance
Accurate fuel injection control
Consistent engine operation under different driving conditions

When the original sensor becomes worn or damaged, common symptoms may include delayed acceleration, unstable idle speed, engine hesitation, poor fuel efficiency, or an illuminated check engine light. Replacing the faulty component with a reliable TPS sensor can help restore normal throttle control and improve driving performance.

Before installation, customers should confirm the OE number and vehicle application to ensure correct fitment.
