3 Way Coolant Valve

[iplax13]

My truck has been having intermittent check engine light and now it’s on full time. Mechanic told me it needs a 3 way coolant bypass. Does anyone know anything about this? He said it’s an easy fix I can do myself.

Had the same CEL symptoms
Did not get any codes
Dealership diagnosed coolant valve
Vehicle was under warranty so dealer replaced
They mentioned having to open it up quite a bit

So I have replaced it and the light after resetting is back on. I’m at a loss here. Heard there is a programming issue with this. Anyone know anything?

The CEL on mine did not come back after having the valve replaced
For any electronics issue I always try deenergizing to see if that fixes the problem

i have the same problem. is it usual for the mechanic to say it just has to reset itself? he told me to just keep running it like normal and the CEL should come off by itself. he told me that if it doesn’t by thursday to swing by and he’ll take a look at it for no charge.

After having mine replaced they mentioned that the CEL might come back on, and it could take a while for it to go off by itself

Sometimes it’s not the three way valve that throws the CEL, it’s the electrical sensor attached to it. Double check the connection and make sure there is no gunk or corrosion in the plug. Also aftermarket electronics don’t always play nice with Ram trucks. Hopefully you used a Mopar part.

yeah, so a little update on how that went for me. it seemed like everything was going right on the truck. but now i’m getting a service electronic throttle on the dash. drove it from nashville tn to knoxville tn. (3 hours) and just as i about got home it popped up. when that happens it won’t go past 10mph, and when i’m going let’s say 60 it feels like it shifts all the way down to first. also if i leave it like that without turning it off it will start overheating. had the gas pedal with the sensor in it replaced monday. and now i got it again today. got stuck on the interstate for about 40 minutes. but managed to make it home. i don’t have the slightest clue to what’s going on. it’s driving me nuts.
