Throttle Position Switch (TPS) Fix
 

Not a question for once, but a sharing of knowledge (something I intend to do a bit more going forward).

Recently, I noticed that the idle Throttle Position Switch (TPS) in my LH2.4 B200F was playing up... But only the idle one. Long story short, I ended up buzzing out the switch module itself with a multimeter set to continuity and found the idle switch itself to be faulty. I decided to open it up and see if it was repairable before shelling out £50+ for a new one, given it's literally just two switches and I'm an electronic engineer.

The TL;DR is that one of the internal contacts was basically not making contact anymore (very marginal, occasionally made contact if the slightest pressure was applied to it) and 5 minutes of soldering later and it was fixed.

Below is a link to a full write-up of it including the fault-finding process, how to remove and open the TPS module, the repair itself, and general information on the TPS operation.

It might be worth sharing/linking this in other redblock-platform forums as well since this is (as far as I know), generic to any LH2.4 system.

Feel free to post any related questions and/or critiques of my write-up, I can edit and add pretty much anything within reason, although I'd rather not remove it again to grab more pictures (although I'm aware they are somewhat lacking).
