throttle position sensor

Hello all, How on earth do i remove the TPS from the injection pump? I cannot remove the screw closest to the engine. Is there a special tool? Ive developed shifting issues after an injection pump rebuild (very late shifts, extremely sluggish) and i suspect the TPS was reinstalled incorrectly...

Start the car, it would run for a couple seconds and then dies out. Sometimes it just cranks and takes multiple tries to start it. Immobilizer light goes out when I put key in. We replaced the fuel pump, fuel filter, the throttle position sensor where the cable goes into AND the other throttle...

About 2 years ago I got a P0120 code (interestingly this was when I was playing with the transmission kickdown cable) right before a trip and decided to just buy a new TPS and be done with it, and that seemed to have worked, until the last few months. Now I am getting a P0120 code...

So I have been fighting a code 41 after a full rebuild on engine. Pulled off the throttle body and tested the TPS on bench and adjusted per fsm. Then installed on truck and tested to the ECM per the fsm. Everything is in spec. Now I did have to replace the harness clip to the tps. I checked with...

Hey all, I'm hailing from south of Denver with an '01 LX470. It has been the subject of a few threads on here I believe, from the previous owner a few years ago. I have been an occasional wall fly for the vast knowledge here over the years, for my '93 LC and now this beast. But figured I'd join...

On a 1998 LX470, are there 2 throttle position sensors? When I search for the TPS parts, I get results for both of these images. I can locate on the truck the one that the throttle cable goes through but haven't found the other sensor. Where is the other sensor located? And, if I am getting...

Hi Guys, Does anyone know a trustworthy transmission shop in the Trinidad, CO area? I'm on a road trip and my LC decided to s*** the bed... I was going uphill on the highway at ~70mph and ~4k RPM when she suddenly lost power to the wheels, redlined to about 5.5k, and started making a weird...

Got a 41 code the other day on my '91 along with rough running/loss of power followed by sudden return of power. Pulled TB to clean (fair amount of carbon build up), and TPS to test. Set up TPS according to manual (was about a hair off at 0.93mm between IDL-E2 - set, tightened screws, and...

Hey mudders, Having what I believe is a throttle position sensor issue, but I’m not sure... Here’s what’s going on: My car started and was running fine per usual, then I hopped on the interstate and floored it hard until I reached about 85mph. I turned off of the interstate and floored it...

Throttle body off a great running 94 FZJ80. Has the IAC valve and TPS sensor still attached. $60 plus shipping from Florida (32433) Also have a 2nd working IAC valve I had as a spare. $25 plus shipping. Thanks

im sure there are already some threads on it but I'm have a hard time fining them. I'm getting a code for my throttle position sensor does anyone have any tips or tricks or do's and dont's before I dive into troubleshooting this the hard way? It's also showing a water temp sensor signal fault...

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...

Mine disintegrated. Does anyone know where I can get a replacement? Thanks.

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

dear fellows i want to adjust my TPS of hdj81 1hd-ft 24valve because i rebuild injection pump and nozzle but now lack of power in initial gears.accelerates slowly like someone have applied hand break and black smoke as well. i attached voltmeter to TPS positive terminal giving 5.05volts and then...

Hey Guys, I'm having an issue with my throttle position sensor, if I have it connected, the engine wont rev past about 2200rpm, whereas if I pull the plug, it is happy to rev as far as i push it. I've checked wiring, done continuity tests on the wires ect. I'm also getting engine fault codes...

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...

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...
