Throttle Position Sensor or Injector Pump

[Homebrew]

jff45 thanks for your post. It has become very confusing. After reading your reply I decided to rechecked for the umteenth time the old TPS with a multi meter. It has now found life again after about a week of death. I reinstalled it on a temporary basis into the Patrol and tested it with the ECU Talk. Again it showed life, although the readings are down compared to the new one. I'll change it back again and start looking further under the bonnet.

Found the problem. It was the small switch screwed closest to the accelerator arm and has the wiring terminal above the TPS. I checked the resistance and found it to be faulty. Unfortunately the switch isn't sold separately in Australia and had to buy a complete accelerator assembly.
Thanks to the fellas who had input.

Well a new development with the cause of the throttle failure. I removed the micro switch and as an after thought I re tested it with a multimetre. It worked fine as per specs. No resistance with pedal up, resistance when pedal down. I then noticed that the neoprene buffer or button, similar to the one between the brake pedal and brake light switch, was stuck on the micro switch side of the assembly. It was not allowing the switch to disengage and complete the circuit. The same has happened with a few cars I've owned where the button on the brake pedal falls off and leave the brake lights on until you notice the issue or you have a flat battery. Never had one stick before.
All the time and effort........ Anyway, I won't be needing a new switch after all.
