To find it precisely:
1. Locate the throttle body: This is the large housing with the throttle plate inside, connected to the accelerator cable. It's usually near the front of the engine.
2. Look for a small sensor: The TPS is a small electronic component, often rectangular or slightly cylindrical, usually with a wire harness plugged into it.
3. Follow the accelerator cable: The TPS is positioned so it can detect the throttle plate's position via its linkage, so it will likely be near the cable's connection.
Important Note: Due to variations between engine types (2.2L, etc.) and potentially different manufacturers' parts, the exact location *might* vary slightly. Using a repair manual specific to your Reliant's engine is highly recommended for precise location and removal/installation instructions. A visual diagram in that manual will be extremely helpful.
