How To Replace Throttle Position Sensor S10 Blazer 4.3 V6

[@buguy3349]

Great video with practical solutions on how to replace TPS. Even at 72, with the help of this video, I was able to replace the TPS in my 2002 S-10 V-6. What a difference after the installation! My S-10 runs SO MUCH better. Thanks again for this video.

[@MariaGonzalez-iv6eg]

Thank you for the video. I changed mine by myself. I saved so much money. I'm so proud of myself.

[@dji1724]

My 93 2.8 s10 was idling fast so I KZbin searched after a few videos I came across yours before I watched it I bought a tps 40 bucks put it on now it runs great !

[@JimEdwards-e7k]

Great video. The only thing I did was move the coolant hose out of the way rather than taking it off and I had a Allen type wrench T20 tool that made it a lot easier to reach and remove the 2 bolts.

[@HossStyle1]

Your other video brought me here. Thank you for sharing.

[@RudyRamkissoon-e2i]

Thank you….replace the TPS on 1997 Chevy Suburban and it fixed the 1st to 2nd hard shift

[@hugh-jassgarrett1914]

Thanks for the video, huge help for me in replacing my TPS.

[@RoninOfTheNight]

Thanks for the video. I wasn't getting a code for the tps or maf but both were going bad. The main problem was surging while accelerating and would lag changing gears. It didn't idle very well either.

[@RoninOfTheNight]

Mine is a 2001 blazer 4.3 btw. Basically the same though

[@hershmyster]

Thanks for this video! Extremely helpful. TPS replacement successful. Thank You!

[@colehagen7998]

This video helped a ton thanks man!

[@jcclopp3121]

What was the reason for replacing this? Was your truck accelerating by itself?

[@alexsbikesandmotors]

transmission was shifting hard. I made another video talking about the TPS and how it affects the trans

Why can I find a mechanic as well rounded educate as u in Los Angeles. My 95S10 blazer had everything from new pump/tank new spider inject MAF Cap Rotor wires plugs IAC and still had an idle issue.

yeah a seal in the ac compressor is bad so i bypassed it by using a shorter belt and removing the idler pulley.

gonna give this a go tmr on my 99 blazer dont shift hard from 1st to 2nd unless i drive for a hour or longer. i hope its not the 1-2 shift accumulator

Unless you break the throttle body gasket

Thankye thankye thankye u gotta new subscriber

[@thedailybench2527]

Would 1,000 rpm be a high rpm idle? I also Have a hard shift from 1-2 when engine is hot. I also get a p1870 code would this help my situation? Where do I get this part? Would the one at the parts store work?

[@alexsbikesandmotors]

yes 1000rpm idle is too high for a hot engine. should be around 650-750rpm. p1870 is almost always set by an internal transmission problem and not tps. You could try replacing tps but I doubt it'll fix it. Best place to get one is ebay. search th149

[@mrbreezeet1]

1000 RPM is High Yes!

[@mrbig4514]

I replaced the same thing on my S10 but just a few days ago it shifted hard into second gear but I replaced mine like a month ago or so now I'm wondering if it needs replaced again and it seems like it does it whenever I go on long drives for more then an hour. should I replace it again?

[@JillyBean860]

My 98 Chevy Camaro does that too. If I drive it for a long period, it will shift hard. It also shifts hard on really hot days (over 90° or so). On cool days or quick drives, it shifts just fine. Very strange. I haven't changed the TPS yet though so I can't say that I've tried this yet. There's some other cheap part (can't remember what it's called) in the transmission that people say fixes the problem. That entails dissecting the transmission though.

[@mrbreezeet1]

[@roadstar499]

What are the symptoms???

[@alexsbikesandmotors]

symptoms are high idle or idle speed changing randomly. Also hard auto transmission shift

[@erniegonzalez4732]

What is that black thing your removing what slides off.your whole hand is on it to lift it. I have a 1996 chevy s10 4.3 engine by the base it crack trying to order without a name nearly impossible

[@alexsbikesandmotors]

Its part of the air intake. I dont know that it has a name and i doubt you could order a new one. You could probably get one at a junkyard easily though.

[@pcowdrey]

Ya! You said that- if you leave off the little breather tube (Ya!), that it will not (Ya!) make any difference (Ya!) in the running of the (Ya!) engine, but what it will make (Ya!), is some dirty under hood air, thrown up from the tires, unfiltered (Ya!) will bypass the (Ya!) air filter.

[@2448teresa]

What is the sensor you unplugged from the big hose on top?

[@alexsbikesandmotors]

Intake temperature sensor and mass airflow sensor are both located in that big air intake hose

[@asayaisrael2859]

What do you clean it with? You mention to clean it up

[@alexsbikesandmotors]

brake cleaner works well

[@asayaisrael2859]

I think that's what's wrong with mines, it shifts real hard like a jerk when going into gear

[@katanatac]

How come you didn't disconnect the positive cable instead of the ground?

[@alexsbikesandmotors]

You can disconnect either battery cable but if you disconnect positive and leave the negative and then accidentally touch the positive terminal with a wrench or something it'll spark

[@mrbreezeet1]

All the time you are to disconnect the negative cable first or only and hook the negative cable up last to avoid sparks!

Jason, did this fix it for your hard shifting? Mine does the same thing (98 k1500) after driving around 30-40 min. Totally fine before that. I have the error p1870. Thx.

how about if you fluid smells burnt or it's don't smell like oil

then change the fluid. you gotta drop the pan to drain it so its a good idea to replace the filter while youre in there.

[@albertcassler8763]

Instead of draining the coolant to remove the top radiator hose, wouldn't it be better to remove the throtel body ? After all its just a few small bolts, and would require less time and less mess...duh

[@alexsbikesandmotors]

You dont have to drain the coolant to remove the top hose. Its the highest point in the cooling system so you hardly lose any coolant. Taking off the throttle body takes longer and you risk damaging the gasket

[@mrbreezeet1]
