Well, it's not as bad as catching Covid, but my baby's dead in the water and I'm getting stumped. My accelerator completely died 2 weeks ago, still had the OE unit in, cussed and swore appropriately, and ordered another one to get me going. Has all the usual symptoms, was intermittent out of the blue, then it dropped to idle and stayed there. the SES light comes on when the pedal is pushed, goes off when you release. so if it's throwing a code, it's a soft one... I'm getting my AE fired up to dig in tomorrow. So my 1st replacement shows up 4 days later, last week and installed it the next morning, worked fine, put about 2hrs total drive time on it when it crapped out again. thought it was a defective unit, so I called the company back and they sent a replacement, It showed up today, I installed it, fired it up, did not move it at all, blipped the throttle 2-3- times, and shut it down. figgered I'd take it for a spin......Nope, went to start it up 10 mins later, it runs, but back to no pedal at all. Idles just fine but nogo. SES comes on when you push the pedal down, but that's it. So that's 3 assembly's 1 OE, 2 New. No Love. Back to cussing and kicking things. Just spent the last 2 hrs looking thru the archives, not much there. Lot's of theory's, but i've eliminated 50% of the obvious ones. I'm starting to think it's in the wiring, although I've been rattling the harnesses around and haven't found any suspects yet. I picked a hell of a day to quit drinking........
Any Pearls of wisdom gratefully accepted.

 

Pull codes so you don't go off on a wild goose chase. Check to see if the IVS is sticking.

 

Oh yeah, definitely. in the morning... and as far as an IVS, this is the 3rd New assembly and I have the same result from all 3, I'm starting to think it's in the wiring somehow, and the pedal wasn't bad after all. Besides, you can't get to the switches on these *******s without pulling the fused plate off the side. thus making them un returnable... I don't mess around with 600$.... even if it was FREE money. ( adjustable pedals).

 

There were issues with the wiring becoming separated from the pins on the harness on both ends. Did many back in the day. Probably reducing OHMS when you moved the wires until the resistance increased again.

 

Oh yes. I forgot you replaced entire assemblies. Well, pull codes and monitor pedal PIDs.

 

Thanks Guys, that's my next move, I'm not looking forward to wiring diagnostics, Not afraid of it, but what a PITA...... and it just started raining really hard. My Karma is having it's way with me on this one. Oh well....."Once more into the Breech Lads!"

 

Sir, it may or may not be of use to you, but there is a PID to watch the TPS and IVS within FORScan. Perhaps get a helper to watch the PIDs as you get under there and wiggle the harness, connectors, etc and maybe identify the problem spot.

I see you received the FSM download, so you should have access to any and all wiring diagrams you require. I am not as good at finding what I am looking for as Leonard is, but I can usually fumble my way around until I find it. If you need help finding something, don't hesitate to ask for help.

This is a great community full of helpful and knowledgeable people.

 

First of all, Please don't call me sir, I'm still working for a living..., and yes, I'm hitting my Books Hard. I've been a Die hard AE abuser since Tugs extolled it's Qwirky virtues way back when, I just had to get my A#$ updated back up and running. Ever Forward!

 

Fair enough... I will refrain from calling you sir.

I don't have much experience with AE, just what I know from reading the posts from guys like you and the very detailed threads from Tugly. I almost jumped on the AE bandwagon for all of my vehicles, but then saw Torque Pro was being used as a cheap alternative. I quickly grew to hate and loath TP because it was a temperamental pain in the *** most of the time. FORScan came into my life and then FORScan Lite as well. I figured for $5 (for FORScan Lite, FORScan is free) and it working every time without fail, I could deal with the archaic aesthetics it has.

I have always said TP is like that supermodel that looks great, but is a huge pain in the ***, where FORScan is the girl next door that is still damn good looking and becomes your best friend.

AE is the Supermodel that wants Maintenance Payments and an Apartment !!! Oh, and I'm of the Opinion that you can't really call these FSM Diagrams true WIRING diagrams, they're more like Flow Charts, You've got to stare at them longer to get anything out of them.......

 

I agree with you on that point. I almost purchased a non-business license on "All Data DIY" for a fee since the cost is somewhat negligible if only purchasing one license for non-business use. Those repair manuals and wiring diagrams are in color and can be viewed as a whole component if desired, as I understand it anyway.

They also have the "flow chart" views, but are seemingly much more user friendly. For me though, and my own use. I have the time to stumble around the flow charts of the free FSM until I find what I need.

Keep us updated on your progress.

 

Dead Pedal News Update! : P0221 Throttle / Pedal Position Sensor / Switch B Circuit Range / Performance Problem. I ran Codes and recorded 2- 5 minute Logs of pushing the pedal. AND....The pedal works, No drop outs, blank spots, just up and down. Volts also recorded, tops out at 3.9 v up and down. Cleared codes, and pedal still dead. So in my mind, the pedal is talking to the PCM, so the wiring is good between the pedal and the PCM.... Yes? or am I missing something? I still need to do pinpointing, but i'm trying to center my task first

 

Verified the IVS is deactivated at the same time pedal is depressed?

 

Haven't figured that one out yet, AE doesn't have vision on that one, or I haven't found that button yet. Back to the drawing board.....

 

I had a dead pedal issue years ago. Mine usually reared its head on a cold start. Truck would fire but have no pedal response. Let it run for a few and slowly but surely, the pedal would come back. Turned out to be a sticking IPR that would free up once the oil temps came up. I had no codes, just symptoms. Your issue may be different but I figure its worth adding to the knowledgebase.
