the last truck we replaced the ip had that code and it was low on power and hard to start. he drove it to the shop, and it died and would not start back when i hooked a fp gauge to it. still had 10 psi of fp started, and died. it had the p0216 code.

 

does anyone know anything about the p1694 code cause its on my other truck to?

---AutoMerged DoublePost---

is there anyway to tell if your ip has been replaced before just by looking at it in truck?

 

P1694 Fault In Companion Module No CCD/J1850 messages received from the powertrain
control module-Aisin transmission

ECM
Bus communication failure to PCM.

Is anything done to your trucks?

 

have a ez on one but the other is stock

 

that is just a companion code, means there are other codes. alot of times when u go to clear it that code wont clear and will stay on the truck.
