So I put in a new APPS from Timbo due to having a couple codes that suggested the problem was with the APPS (low voltage/high voltace and a general fault code). Installed the new APPS and checked the voltage as informed and was only at .475 and wouldn't go past .488 with wide open throttle. Any ideas of what may be causing this low voltage? No new parts and has ran great the last year. Thanks!

 

check the 5 volt line feeding the apps..sounds like gone..

Where would the 5 volt line be located?

 

Timbo has been a great help. Going to check the vlotage from the ECU in the am. Lets hope it is a simple fix but my luck it wont be. Anyone have an idea it will cost for a new ECU if that is the problem?? Thanks as well to you dkenny!

 

you should be able to find the 5 volts on the connector at the apps.

if it were me and 5volts from the ecm gone I wire in a $5 circuit using and LM7805 voltage regulator.
