    3-FE Throttle Position Sensor Reading

    My truck has not been herself after a HG replacement last year. Like a Land Cruiser should, it still fires up each time, and plugs along like champ. I know how this engine feels when its happy, and it is not there yet. I wanted to check the TPS sensor, since I am not certain if it was checked...

    So I'm getting an error code 41 from my O/D light, and I don't have torque converter lockup since my injection pump rebuild. The Error Code 41 is: Throttle Position Sensor. I did the resistance test on it and it ohms out ok. The wiring harness seems ok, and I've already (foolishly) replaced...

    Throttle Position Sensor

    I just got halfway thru a TPS check and it started pouring rain. I checked the fully closed and fully open positions. They are within spec. My question, has anyone ever heard of TPS being partially out of spec? My guess would be yes, but ... Thanks

    how the heck do I adjust the throttle position sensor?

    so my 62 has had a high idles since I bought it in February. I've read all the posts and it sounded like it was the TPS that I needed to adjust. I bought a multi-meter a couple of weeks ago to do the job. Finally got the time this weekend to take apart the throttle body, clean it out, and...

    TPS testing question...

    Hey folks, I've got a '89 62 basically all stock. I went out to test my TPS due to code 51 and just to make sure it's all in adjustment. I just want to make sure I read the diagnostic procedure correct on which terminals to test. There are 4 terminals on the TPS, the bottom 2 are supposed to...

    Air intake manifold / EGR service? Pic heavy!

    My 1990 FJ62 has always idled a little high at 900 - 1000 RPM for as long as I've owned the vehicle. So I started a project this weekend to clean out my throttle body and recalibrate the throttle position sensor. Turns out that the throttle body was already pretty clean but the air intake...
