Thanks for the video! You went more in depth than some of the other videos here. Using your method I found what seems like a dead/worn spot on my tps during the transition from idle position to wot. At about 25 - 35% from idle, measuring voltage only instead of the smooth progression of increasing value, it dropped down and then shot back up continuing like it should. I experienced this during my driving but never knew what caused the problem, it felt like I would lose power at a certain point during my acceleration but at cruising speed it would be ok. I replaced the tps and I don't have that issue anymore, again, thank you for the great video. It helps when things get pointed out and then I can test it for myself to find the problem. Mahalos!

I find your videos are some of the most informative without getting overly technical with information that we don't really need to know. This helped me diagnose my tps and move on to find the real problem. Thanks brother

What I really appreciate about your video is that you gave clear & easy instructions on how to use the DVOM & for the 1st time I totally understand how to use it for testing my TPS! Thank you 🙏🏽 sir!!!

@lloydedwards500 4 года назад

Thank you The diagnostic procedure of the throttle position sensor is exactly what I need to know. Discovered that my TPS was outputting 4 1/2 Volts at idle ,closed throttle plate . Thank you again.

@michaelpena5941 8 лет назад

I knew something was wrong with the TPS but wasn't sure. If I hadn't of seen your tutorial then I would've purchased one off of ebay without being sure that was my problem. Thanks a lot for your help, your video was very informative.

@julesramel2487 2 года назад

So glad I found this video! Thank you! My intuition told me throttle position sensor initially, but advice from others was possible cma shaft sensor, Pulled codes that confirmed throttle positions sensor but not sure I can trust as this car was used when I bought it with a rebuilt hyped up racing motor. The wiring is sketchy. With that being said, having this knowledge lets me trouble shoot before buying the part! Car idles very rough when cold, and idle will increase then decrease on it's own. Slight acceleration issues as it doesn't immediately respond to pedal pressure. Runs better when warm. Idles great at higher speed. It does need exhaust running from the headers and back. These are racing headers so I'm unsure how much vacuum pressure plays a role. I have spark, but no start. In my research a no start is rare but possible. Any thoughts from others is graciously accepted :) Aware it could be timing, but want to start at the easiest point and work my way to that.

@wmg4686 7 лет назад

Dude thanks a lot for this video. I have the "Circuit low input" code coming up on my GMC Sierra. This enabled me to check everything and put in a new throttle position sensor as well as repair a wire in an O'Reilly's auto-parts parking lot! These types of posts save people a lot of money. Thanks again!cheers bro

@automotivated5934 2 года назад

Unless someone is straight up giving harmful information why would someone thumbs down it. Lol. I have a “competing” channel that is small but growing and I have people trashing me too at times. Thankfully the vast majority are good people and trying to learn. I look at it as we are all on the same team. We are all looking for automotive knowledge. Haters Gonna Hate though! Haha. Good video man!

@dianaivery74 2 года назад

Like me, I found this is a great video and easy for me to fix my own throttle body work ,instead of having someone else do it. Plus I'll be saving money doing it myself...

@Bahai111 8 лет назад

I have had it running well, then it just does not want to get up and go! If I didn't like the motor home and I didn't like the 460, I would walk away and sell it! Thanks, Rick

I am so glad I found this Igrbetslly search Old jeep issues. Zip cannot thank you enough for explaining everything so thoroughly. I was stumped with why I had crank but no comms no nothing. I did finally find my TPS was like cracked open. I have the new connector and Tps but my existing wire is a small gage the new connector wiring is at least double thickness. So I decided to see if I could find if it anyone else ran into this?

@davidlubin7389 2 года назад

Great video...like your style...straight and to the point! I have a '91 Camaro with an LS1 engine. It has a new throttle body with new IAC & TPS. PCM threw a P0122 code which is low TPS voltage which should be around 0.5v-1v at idle up to 5v at WOT. Voltmeter read 0.13v at idle (which explains the code) and only 3.94v at WOT. Since the TB was new, the manufacturer sent me a new TPS under warranty. When tested, it was perfect...just under 1v at idle and 4.95v at WOT. A day later, the new TPS was back to the same range (0.13v at idle & 3.94v at WOT) which threw the same code P0122. Any ideas as to what could cause this voltage drop? FYI, this is a newly swapped engine. I am at a point of "crank, no start" and am troubleshooting that as well. I do have voltage at injectors and coils, spark and 58psi of fuel at the rail. Thank you!

I've been watching your videos I have a 1993 Nissan Maxima I have a brand new throttle body sensor but when I started is a rough idle I am trying to do everything I can could you give a suggestion on that vehicle and it is a very good program hi Sayler. Keep up the good work Aloha from Hawaii
