My buddies ion redline is throwing that code. It says coolant temps are below regular temp level or something along those lines. I'm still on the debate is what causes that code to come up? If anyone knows chime in.

 

Im not really sure but I would check fan relays make sure fans turn on and such. Or thermostat what is coolant temp when engine is warmed up?

 

I've been getting it too. My car warms up like normal and doesn't over heat. Just need to take it in and use the over priced warranty.

 

Not exactly sure I was with him last night and I saw it and said lets go to advanced to scan it and that's what popped up? I assume once it came on he didn't check it

 

if he's taken off the coolant hose for anything, it could be air trapped in the hose by the sensor.

 

could be we put a 2nd h/e on his car a while ago.

 

Or thermostat can be stuck open. Cobaltss89 had same issue nd he replaced the thermostat. Issue is fixed.

 

Well I erased the code and twisted the cap off to let any air out to see if it would bubble and nuttin so wait and see if the code comes back.

 

For me it was the thermostat also, would heat up okay but once on the road it cooled wayy down and no heat from the heater......

 

you're not supposed to open the cap lol

 

Lol^^^^^^^ I'm assuming,he thinks,that is the way u burp it.. hmmm I'm gonna try lmao; )

 

on the sc coolant, until i thought about it and figured it wasn't that
