Detailed Description

Walker Products 200-1422 is a throttle position sensor built for vehicles that rely on accurate throttle angle input to the engine management system. It mounts on the throttle body and uses a rectangular female connector with blade terminals for a secure electrical interface. The adjustable design helps support correct sensor alignment during replacement on covered Porsche 911, Porsche Boxster, and Land Rover Discovery applications. If you are replacing a worn throttle position sensor on a 1999-2005 Porsche 911, 1997-2004 Porsche Boxster, or 1999-2004 Land Rover Discovery, this part number 200-1422 matches the listed fitment.

This part cross-references Delphi SS11001 for the same application.

Common Replacement Reasons

• Throttle response that feels inconsistent or delayed
• Erratic idle caused by incorrect throttle position feedback
• Check engine light related to throttle position sensor faults
• Driveability issues tied to worn sensor output
• Replacement for a damaged throttle body mounted TPS

Installation Notes and Tips

Confirm connector shape, terminal count, and throttle body mounting style before installation. Because this sensor is adjustable, set the sensor position according to the vehicle service procedure after mounting. Inspect the connector and terminals for corrosion or looseness before final assembly. Verify throttle operation and sensor output after installation to ensure proper signal response.
