Hey all!

I have a 2017 chevy silverado 5.3. I was pushing her hard yesterday down the highway. All the sudden, tach drops to 0, oil oressure to 0, and Stabilitrak comes on. It is still going, but running kinda funny.

So i coast it to an off ramp, cross the intersection and pull it to the side of the road. Jump out looking for oil or any type of disaster. Nope.

I go back to turn it off and on the door is locked. All of them are locked and the truck is running. Kinda panic but i realize probably a short? Wiggled the speed sensor wire and bam unlocked the truck.

So i covered it with the corrugated conduit, and i took off. Then it happened again, maybe like 100 feet down the road right before a red light but the issue went away quickly.

Ideas? Limp mode? Short? Reset the Ecm? Oil looks good no blown head gasket or nothin.

Lifted 6" 35s. I have an F5 tune on her by flashpaq . Refurbed transmission.

Thank you!

sounds like you need to replace that sensor wire.
