Upgraded Throttle Position Sensor Kit — Range Rover Classic

​

Tired of the notorious unreliability of the original Lucas throttle position sensor? This is the upgrade your Classic or Discover deserves.   Designed to work on every 3.5 or 3.9 V8.  The picture shows the unit mounted, and inside the components hides the original 2 screw mounting points, so fear not, nothing is modified when fitting.

​

Our kit replaces the failure-prone Lucas TPS with a proven, modern GM unit — the same sensor trusted across millions of General Motors vehicles worldwide. Known for its precision, longevity, and consistent signal output, the GM TPS brings 21st-century reliability to your Range Rover's fuel management system, eliminating the erratic idle, hesitation, and flat spots that plague aging Lucas units.

​

The custom mounting hardware and adapter components are printed in high-temperature carbon fibre reinforced filament, engineered to withstand the harsh underbonnet environment without warping, cracking, or degrading over time. Strong, lightweight, and built to last.

​

Why upgrade?

​

• Replaces the unreliable Lucas TPS — a common fault point on the Classic and Discovery 1

• Modern GM sensor delivers accurate, consistent throttle signal

• High-temperature carbon fibre printed components handle underbonnet heat with ease

• Direct fit — no cutting, splicing, or permanent modifications required

• Improved throttle response and smoother running

• Up and running in 10 minutes 

​

Give your Range Rover Classic or Land Rover Discover the reliability it was never quite born with, but always craved.
