Engine/Transmission (1998.5 - 2002) APPS need resetting?

[BILLYGEE]

This past weekend I had several occasions when I pushed on the go pedal and nothing happened until I got on and off it several times. The only other erratic behavior is during the past two months under heavy load and acceleration on several occasions the transmission seemed to slip momentarily or go in and out of lockup... Today I checked computer codes(Engine light not activated) and it shows the infamous P1693 and a P0216(VP-44?) code. I've got a brand new comp box in the box and I'm dying to put it in but am holding off just in case I gotta visit the Dealer! I'm thinking I'll try to reset the APPS... Any other suggestions??? Truck is 2001 Auto w/81,000 mi...

It sounds like you are gonna need a new injector pump. Do you have a fuel pressure gauge? Make sure you have at least 8 psi at full throttle.

Does yours , mine for years would rev and scream but no more power! If so the APPS does need to be reset. Turn key on and then slowly depress throttle let up and turn off key do this twice more and then leave key off for over a minute.

Me too!



I have experienced similar problems on my '02. It first happened to me in Dec. , coming back from MI. Was in the passing lane with cruise on, but had to pause cruise because of a slow vehicle. Tried to excelerate with the pedal and nothing happened for 1-2 seconds. Same thing happened again approx. 20 mi. later. Stopped in Terre Haute to get a new fuel filter (but did not install it) but did not have any more problems until yesterday. Traveling down a highway and came to a hill... no pedal! I feathered it two or three times and it came back to life???



I have been searching threads and am wondering if this is an APPS problem?



Anyone have some suggestions?



Thank you.

Thank you.

Turn your key on and off three times, leaving on the third time and watch the odometer for codes. 216 is BAD!



Regarding APPS calibration. I believe you are suppost to disconnect the batteries for 30 minutes (turn on key to drain everything). Reconnect, turn key to run, slowly depress the go peddle and release it, and then turn the key back off. Then drive it - like you stole it.

Same thing happened with my 2002... sudden loss of power (dead throttle pedal) for a few seconds and then it'd be back to normal. Kinda unnerving when you're in the passing lane towing a loaded trailer with other rigs on your tail and all of a sudden you're dead in the water Replaced the VP44, problem solved. 216 means your VP44 is dieing.

 

[bigredcummins]

Well, some good news (I guess)... I turned the switch 3 times and didn't get the 216; however, I did get the 1693 code. In looking at other threads, this appears to be a red flag that something did not come up normal. Perhaps I should try APPS calibration???



Thank you for your help,

Craig - you can try the APPS because it's free and easy, and maybe will help. But plan on a lift pump, VP44, and a fuel pressure gauge. The absence of a 0216 code doesn't mean a good VP44 - there have been failures with no code.



The good news is that the VP44 and LP are warranty, unless you are over 100K or have tapped the pump wire.

 

[bigredcummins]

Thank you for the info. I am under 100k (58K) so that is somewhat comforting (although I never consider taking any vehicle to the shop comforting)

Saw in your sig a K&N. Take that off before you go to the dealer or they might complain about it (washing the turbo & oil in the intake).

Probably a non-issue, but there are two sets of codes (ECM & PCM?). Are you certain you watched the entire sequence? 1693 means there's a problem in the companion unit (ie. watch the other set of codes for the error). You should see P DONE twice, and you're not done reading codes until the odometer reappears. Every time I've seen 1693 there was an accompanying error code in the other unit.



As NPS mentioned, resetting the APPS is free and doesn't hurt to try it.

 

[BILLYGEE]

Went thru whole sequence... Been there done that... codes were P1693 and P0216, PDone, ECU Nothing... then odometer...

Not you, that was meant for Bigred He said he got a 1693 but no other codes, so I was just verifying that he went thru the entire sequence. I've had a 1693 a few times now and every time it was accompanied by another code.

Yep, you are right. I ran the code again and this time watched it all the way through. Sure 'nough... 1693 followed by 0216.



Thank you for the clarification.

I've got the same set of codes; pcm 1693 and ecu 0216. Thought i had things fixed after changing the LP. . but still get an occasional dead pedel.

Any idea how much time 'till the VP die's for good. The truck starts and runs great other then that dead pedel crap. Also, will the dealer change out the VP on the codes alone or will they want more proof that it's not working. If they take it for a test run. . it might go a long way before showing symtoms.

i am having the same problem, i am going down the road, and if i let off of the accelerator, sometime when i press it again, nothing. no power at all. then i can push the clutch in or downshift, and the problem with temporarly go away, only to come back a short time later. the only code i have is the p0500 (vehicle speed sensor) what do you all think i should do. this is scaring the he** out of me. i have a 2002 with 62k miles. thanks guys. :{

 

[shouldbeonmyboat]

Greetings, As many others have commented here, I am having the exact same problem. I understand that the engine will still be under warranty as it is a 2002 with 63K miles. Can any of you recommend how I approach the dealership on getting them to fix this on their dime. I am low on funds and if the problem is covered under warranty I don't want to say the wrong thing and not have Dodge do their part.

As long as you don't have any obvious modifications to your engine (chips, etc. ) just take it into the dealer for repair. It's covered for 5 years or 100k miles.

My concern is in finding a dealer that knows what they're doing. My truck has 70k miles on it and the occasional dead pedal is just annoying at this point. I'm going to spend some time finding a service department with real "hands-on" experience replacing injection pumps. This job is a little more complex than changing oil and filters.

[shouldbeonmyboat]

You nailed it. That's my big concern. If something has failed I want it fixed one time only and move on. Thanks for your valuable input.
