hello i just installed a new vp44 injection pump and new filter as the other day truck just quit on the highway so the garage says it needed new injection pump ok so got that done now as i drive the truck down the highway around 80kmh the truck starts bucking like starving for fuel but drives fine at 50 kmh could it be this sensor causing this issue ? its a 2000 dodge ram cummins 3500 5.9 diesel i dont want to be spending piles of money troubleshooting this fix

Got Thumbs says:

Excellent!
Just installed a new TPS/APPS on my 03 3500 5-speed. Most difficult part for me was getting the probe properly set, it was simply a matter of gently nudging the APPS to get the .55 after tightening the screes. She's set perfectly, thanks to your great video.
One more satisfactory purchase from Thoroughbred.

Spencer's Garage says:

My 2003 5.9 does not have it in said location in front of the intake elbow. Any idea why? And here could it be?

Earle Clemans says:

How much do you know about swapping these engines?

paul sharon says:

Wade you're the best. If and when I have problems with this truck I dont drive I can always rely on you to make a video to fix it and you do it so even a cave man can do it.

Kerry Werner says:

I have an issue where my truck falls on it’s face while driving, thinking it was my Airdog pump going bad I replaced the Airdog with a new pump, that lasted 2 weeks,
Guess I should try this next. The only code it’s throwing it a P0837

Luis Cordova says:

Do you say the sensor from your website store are set to just replace it and good to go?

Jason Cable says:

So I installed a new APP S and I can't get it to adjust out to 5.5?

Ulises Pradera says:

Good evening, I changed in my ram 3500 2001 diesel the TPS sensor calibrated at .55 v but in the calibration test it does not exceed 1.99 and it becomes OL and remains dead

Thomas McCray says:

My cts2 screen went bad on my 99 5.9 so I called thorobred, the guy talked me into buying a cts3. After talking with an edge rep at edge he told me to send it back and that it was not compatible with my present edge, so I sent it back and was deducted 65 dollars to reshelf it, really. WOW THEY'RE HURTING.
Never order here guys a bad apple is still a bad apple even when put with fifty good ones and made apple butter. Bad is bad. I went right to edge and he fixed me up with a new one for less than 100 dollars. The original cts3 from thorobred cost around 365 dollars, which should have never been sold to me.
Bad apples all around.
There are too many other good places to buy from. Amen.

Janet McLaughlin says:

Your video saved the day! Thanks for the detailed explanation and video. Hubby was able to install the part in the parking lot of the dealership where we purchased it while we are in the middle of a 4 state, 17 day trip. Great job! Thank you.

Daniel Medrano says:

So if I order from you guys I dont have to set it up? Is basically just swapping parts?
I possibly need to order one…

These Truths says:

Maybe you know the answer to this unique issue I have on my 2005 Dodge Ram 5.9 Cummins automatic w/overdrive transmission? 196,000 miles.
It's the original transmission and motor. All fluids/oils and filters regularly changed and kept clean/new. Not used to tow often…4-5 times a year at most and 8,000 lb loads at most.

I've asked 4 tranny shops and a few forums and Facebook groups but no luck finding same problem or proper fix. I'm wondering if I'm just that special?!?? Lol

One mild Fall day last year I had driven 260 miles on interstate at about 75-80 mph. It began slowly reducing speed over 6 miles from 80 to 15mph. Moving fuel pedal would not do anything but make it stumble a little a couple dozen RPMs up or down. Stopping and restarting it immediately did not help nor did changing gears manually.

All fluids were fine, not too hot and no burning of anything fluid or conduit wire was observed. All looked good under and above it.

I stopped it for 30 minutes as I checked it over. It would drive normally after that, but it would only go 25-30 miles before it would slowly slow down again as described above. I did this over many cycles all the way home 260 miles. I'd turn it off and on again, completely off as it rested for 25 minutes. The batteries seemed to be getting charged (started well each time) and no warning lights were on. Once or twice, when I drove it until it would not even crawl anymore (1-2 mph, I was testing it), it stalled. So it wasn't hard starting or hard-stalling unless I took it all the way down to 1-2 mph speed. It was not idling weird either.

Could this be an electrical ground failure or electronic issue? If I had a battery connection loose or anything disrupting the flow could it cause this? It seems like something is getting tired and needing to cool down or something but nothing was overly hot or smoking. What's weird to me is it's not slipping in the usual way of revving up but not moving. It would usually get no lower than idle.

Tranny shops haven't heard of this before. No transmission codes either. They want to charge me $3,000+ for new or rebuilt tranny. I want to rule out wiring and electronics (that don't throw codes) first.

Any suggestions? Heard of this ever before for an automatic transmission?

Thanks!

Philip Pierce says:

My 1999s batteries died so I charged them and reinstalled them. It started up fine. But as soon as I hit the throttle it went to 3,000 rpms so I cut it off. Tried to reset the apps but it didn't work.

Mike Miller says:

I don't have a yellow wire

Dameyon Brooks says:

Men doesn't throw a code, just loss of pow when attempting to accelerate, truck idles fine& doesn't go dead.

Savage Mike says:

Old video but would a bad or messed up tps sensor cause overdrive to no kick in? It randomly pops a tps code but when I turn the truck off it disappears

Arthur Walker says:

my truck only has idle and wide open throttle as soon as you touch the pedal.1998 Dodge ram 2500 Cummins. Any info would be appreciated, thanks.

ZayZayOG91 says:

l I having a problems 2006 6.7 3500 Cummins I think it's the throttle or the pedal but it's something similar to this lose power as i step on the pedal??need help!!

SJ Line Coach says:

The torx screw in front of where the throttle linkage connects adjusts the voltage as well, is there any reason you didn't use it and manually adjusted it by turning the sensor itself before tightening it down?

Climbing Without Passion says:

Now, how to clear the codes. . . .? Youtube search

Climbing Without Passion says:

I did it! Solo; in about 15 minutes, even with adjusting the voltage. I'm no mechanic, so thanks for the video! So pleased–the part was $35. . . .
