The TPS outer case unplugs, it's a bit fiddly, i normally gently use a flat key to unhook it.
With key in ignition switch it on (don't start engine).
Unplug the TPS
The rev counter needle should go to 3000rpm.
Then plug it back in and the needle, if positioned correctly should land on the 5000rpm mark.
If it goes to 0rpm or 10,000rpm it needs adjusting back to 5000rpm.
If it goes to 3000rpm it's totally knackered.
To adjust it the 2 screws need slackening with a security torx allen key, then rotate the TPS unit until it lands on the 5000rpm spot.
Be aware, these units can slowly break down rather than just stop working so can misbehave for a while until you realize it needs replacing.
