Black24vCummins1999

the last 2 apps sensor i have bought for my truck did not cone with a tag i know that you are supposed to set it lower than what The tag says but how do tell what mine is supposed to be set at.

Ok. I followed the link for 2nd gen 24v and went to troubleshooting P0122. The procedure you posted is a little diferent. I will follow these when I can and advise. Thanks

Step 7 in the diagnostics state that if the resistance is 5 ohms or less, replace ecm. My reading was 1.2 ohms. Am I understanding that correctly? Thanks again fir your help

the resistance between terminal 5 on apps and terminal 31 on ecm connector 1.2 ohms

i was able to work on my truck today and i have no voltage between my apps connector and the block what does this mean.

Thanks I will try and check that soon and let you know what I find

Thanks for the reply and as of right now I have red the diagnostics to check the continuity from pin #5 on my apps to pin #31 on my ecm but have not had the chance to check it yet. It seems really hard to get down to the ecm to get a good look at what I'm doing.

I have a 1999 2500 Cummins 24v that keeps getting the p0122 tps low voltage code on every tps the first time I changed it, it lasted a week then got another dead pedal so I replaced it again thinking I got a faulty tps and the new one last 2 days and I got the p0122 code again and the truck surges off and on. Ive did the reset procedure and it idles fine. Any ideas to what could be causing me to keep getting these problems thanks.
