Just a heads up on replacing your Crank/Cam sensor.
First off might wanna pull your crank sensor and check it. When I was down there I noticed it was worn pretty badly, I assume from grit getting slung across it for 15 years. I’ll post a picture in a bit.

I had two sensors on hand I bought as a spares from rock auto, I believe it was an Ultra-Power brand. I threw it in and went on my ways.
Truck started stuttering at higher RPM when towing. Also idled rough. It had never done this before. Ever. No codes, and I checked the wires by the AC compressor. Since I had just put on a new crank sensor, I stupidly decided to change the cam sensor too (I still had a spare). It absolutely messed my truck up. Super extended crank, and on the test drive it started puking a horrendous amounts of black smoke, and knocking (I believe and injector or two was just held wide open). I shut the truck off and restarted it and it no longer smoked or knocked. Ran codes and got a P0016 and P0341.

Came to the conclusion I must have had a defective sensor (I’ve installed them before many times so it wasn’t my mistake). Ordered two genuine Cummins sensors Part # 287277. Unfortunately they are made in Mexico. I’m just hoping they hold up good. I still had the originals (the reason I didn’t immediately swap them back was because I had left them at another shop). So far so good. Installed them today and no codes and starts up normal and appears to run fine. If I ever have trouble again I’ll follow up on this thread.

So that was just my write up and two cents on Cam/Crank sensors. Probably stay away from the cheaper brands such as Ultra-Power, or maybe I just got super unlucky!

Good post. And yes. All in the know agree. Only sensors from Cummins has been the standard answer on here since before I joined. Always.

It’s just a shame nowadays that even genuine Cummins sensors are made in China/Mexico…

We have given our country away, buddy. It’s time.
What do you expect when you can't even get people to drop fries at McDonald's for less that $20/hour

There’s no reason to use anything other than a cummins sensor in this case. They’re only $25 each. If the $25 is a problem you need to sell the truck……I changed both of them this year, it’s just not worth the hassle to get anything other than OEM pieces here guys.

Yep, I've got blood on several T Shirts with cheap or counterfeit Cummins sensors and relief valves. I couldn't resist a GOOD PRICE several times. LOL

I'll substitute NGK for a Mopar sensor. NGK makes sensors for Mopar. Again, we have to be careful that it's not a counterfeit NGK.

Over in the gas burner world, we run into counterfeit NGK spark plugs. It's really hard to tell the difference.

Geno's has what we need and I'm confident they supply quality sensors.
