94 CH613 E7 Electronic & Engine Shutdown Lights

[msbulldog601]

Hello Everyone,

I’m posting to get some information that will point me in the correct direction I have a 94 ch 613 Day Cab with E7 Engine pulling a 24ft end dump…I keep getting the electronic malfunction light on the dash it’s giving me blink code 2-2 and recently the engine shut down light comes on now also so both lights are on but the truck does not shut down. Engine shut down only comes on after truck is running for a while whether driving or idle. When it does come on while driving sometimes it will come on and go back off.  What do you think could be going on?

Had the same thing going on with our 1985 mack, Is the truck a mouse nest? I'd bet its the wiring harness if that's the case but check oil pressure and everything else before you listen to the computer. Best of luck

Hey check picture I think it’s the coolant temp sensor behind the water manifold and the wires look damaged think I’ve found the issue what you think? @Joey Mack

definately bad..  "Fix what you know is broke"  Is the other sensor around the corner from that one, or in the radiator tank?
