Heys guys I'm trying to figure my truck out and was hoping to find some help. I've been having problems with my truck and it gets a lot worse when it gets warm outside. thetruck gets really smokey,doesn't want to downshift and sometimes the veins in the turbo are not working either. I thought I would check the codes and this is what I got which is accelerator codes and could explain all my problems. The truck runs pretty good up untill the temps get to high 70's or more outside. I tried a dorman stationary ped and it did not work at all so I put my pedal back in. I have the power pedal but not the wallet to buy a replacement so stationary is what I tried. The dorman didn't work at all until shutting it on and off a couple times and thing it would only work for a minute and quit again. I am egr deleted with powermax turbo,arp studded,custom tunes by tsd,and banks intercooler with idp 58v ficm with a tune. Is there any way to test my pedal or the wiring? I know it send signals to the map sensor and pcm but no idea what to check. I heard these trucks were bad for wire chafing so that was also a thought or maybe just a bad pedal and bad replacement pedal..Thanks for any help

 

No the Accelerater peddel DOES NOT send signal to MAP Sensor

You can check the ACCelerater pedal with a SGII or AE

or maybe a DVM

Check all 3 track of pedal

Any scanner?????????????? DVM????????????????????

 

I keep putting off getting AE everytime I have the extra cash. I really need to get it . I've got a edge insight and a old sct xcal. Is dvm stand for digital volt meter? I got one of them I can check voltage with.

 

Yes DVM=Dig Volt Meter

its a 3 track pedal so you will needd to know what track your testing

here are the Values that you want

APP 0 0 13 0 - 17.75 PERCENT Accelerator Pedal Position
APP1 4.0 4.0 3.4 0.7 - 4.2 VOLT Accelerator Pedal Track 1
APP2 1.4 1.4 1.9 1.4 - 4.1 VOLT Accelerator Pedal Track 2
APP3 0.9 0.9 1.4 0.8 - 3.5 VOLT Accelerator Pedal Track 3

dont know how to tell you what wire is what track though

A SGII will get these AFAIK I havent put these codes in it but there are codes for it AP% and APP123 tracks IIRC

I do have Ap% on my SGII so that does work just not shure on the 3 tracks but Imagine they work

Seams Like Edge Always Falls short when trying to Diagnostic stuff


AE would be awesome
