2000 Dodge Cummins APPS?

From : jackvt80

Q: can anyone confirm if there is an apps on a 2000 24v dodge cummins my torque converter is locking/unlocking between 45-50 mph on my 2000 24v with 110k miles. was doing it a while back but had an unrelated injector pump problem that was replaced and it went away. when it did it then i asked the dodge dealer to price one for me. they said there wasnt such a thing i asked them to check apps and tps... said something like theres a bell crank sensor or something. he even went out to confirm with the diesel tech but i didnt hear how he phrased the question. it sounded to me more like they were talking about a speed sensor. anyway is there one does anyone have any idea what a replacement costs and is it easy to get to based on looking at the archives it looks like its a reasonable bet to solve my problem but i dont want to start throwing parts at it if theyre expensive. im also wondering if i have a bad connection that i should check into if the inj pump replacement solved the problem for 3-4 months. tia. jack .

can anyone confirm if there is an apps on a 2000 24v dodge cummins yep. if your dealership thinks otherwise ask them to look in a service manual chapter 14 under fuel injection - diesel. the first sub-section is all about the apps. anyway is there one does anyone have any idea what a replacement costs and is it easy to get to if max340 sees this hell respond - he recently priced one out. as for location look on the front of the engine drivers side. youll find a black plastic cover round in the front. theres a couple of plastic clips/screws holding this on. remove the cover and theres the apps. typical problems for a tc locking/unlocking while cruising are either a bad apps/tps or a bad brake switch. an obd-ii scanner with real-time capability could monitor the throttle position and let you know in short order if the apps was the cause of the problem. if you have a bit of electrical knowledge and an analog multimeter you could back-probe the apps electrical connector and cycle the sensor through its range watching the needle on the meter. any erratic behavior while smoothly cycling the sensor would indicate a problem. .

thanks tom. i did hook it up to my obd-ii scanner and pressed the accelerator while in neutral no load. the actron scanner i have gives two readings the first appears to be voltage of the potentiometer and the second may be % throttle. at the range im having trouble 1200 rpm it appeared to be working ok at least with no obvious dead spots. i was ranging through 0-maybe 5.3v while messing around. i did notice the % throttle seemed to fluctuate some in the 14-16% range if thats indeed what the reading was. ill try hooking it up and driving it to see what its doing under load. i can also try the analog multimeter you suggested next. it did kick out of cruise control yesterday but only once. so i guess ill try the cleaning the contacts on th brake switch too. thanks for the suggestions. jack .

anyway is there one does anyone have any idea what a replacement costs and is it easy to get to if max340 sees this hell respond - he recently priced one out. as for location look on the front of the engine drivers side. youll find a black plastic cover round in the front. theres a couple of plastic clips/screws holding this on. remove the cover and theres the apps. well my price was for one i bought a year ago and i paid $320 which was with tax but below retail. you might also check to see if your problem is the same one i had dealer tech did not properly connect wiring harness to the apps after replacing the inj. pump. -- max there are four boxes to be used in defense of liberty soap ballot jury and ammo. please use in that order. -ed howdershelt author can anyone confirm if there is an apps on a 2000 24v dodge cummins yep. if your dealership thinks otherwise ask them to look in a service manual chapter 14 under fuel injection - diesel. the first sub-section is all about the apps. anyway is there one does anyone have any idea what a replacement costs and is it easy to get to if max340 sees this hell respond - he recently priced one out. as for location look on the front of the engine drivers side. youll find a black plastic cover round in the front. theres a couple of plastic clips/screws holding this on. remove the cover and theres the apps. typical problems for a tc locking/unlocking while cruising are either a bad apps/tps or a bad brake switch. an obd-ii scanner with real-time capability could monitor the throttle position and let you know in short order if the apps was the cause of the problem. if you have a bit of electrical knowledge and an analog multimeter you could back-probe the apps electrical connector and cycle the sensor through its range watching the needle on the meter. any erratic behavior while smoothly cycling the sensor would indicate a problem. .

thanks max. i am wondering why i had the problem less so than now before the inj pump was replaced and then it went away after replacement. then nothing until a 150 mile trip last night. ill definitely check the connectors first. jack .
