HELP - Apps- Camshaft senor ????

Truck started to act up on my wife Monday night. She said truck was possessed started to take off on its own. She tried the cruise control and it went to 60 mph and back down to 40 mph on its own.

I got in it to drive it home, engine started to rev to 2000 rpm and back down with no movement on the petal, check engine light came on . I've had problems with APPS before but it always reset.

Not this time. Ordered a new APPS senors $287 + tax.

put it on today still does the same thing ????. Any Ideas.

Went out to check again started truck now it just idles no throttle at all. (CODE 1693). Started 1/2 hr later went to 2000 rpm. then back down to 700 rpm then back to 2000 rpm over and over. :mad: :mad: :mad:

P1689.



No Communications between injection pump and ECM.



Bad Connection in the Wiring harness, or bad Injection pump.



Mine turned out to be a bad injection pump. (but I didn't have revving up symptoms)



Others reported teat the code mysteriously dissapeared after a little bit.



TDR Search for "1689"



Sound like what you have? Sounds like my problem. .
