Is there a heat control valve on a Dodge ram , my truck heater gets warm eventually but takes forever even when the engine is up to 200 plus degrees , also the check valves off the intake , do they affect the heat , I do know they are bad and are affecting my air conditioner. It shifts when I accelerate and returns when I let off.

you might have a blocked heater core,the core looks like a mini radiater

SOURCE: Can you have the idle air control valve checked to see if good?

I had a similar problem all it was a the rubber boot after the sensor was sightly disconnected and produced the same code. I would even take it as far if there is a decent rip in the boot would also cause the problem.

and yes you can test it
