This code just popped on my 2020 2500hd. This is the 3rd time the check engine light came on. 1st was for the fan regulator to cool the engine, which came on 2 days from driving it off the lot and the 2nd was for a heating coil. Has this code p20ee been figured out yet? Would like to know. Any had my truck for 3 months. Any help I would appreciate it.
