DTC CODE PO480 fan 1 control circuit
Hello all, got my first trouble code & looking for some assistance with this thing. Im wondering if this is coming from the front fan connection... the reason I say this is b/c during my EGR delete a few weeks ago I was trying to disconnect that fan connection & I couldnt seem to get it loose. so I just worked around it & thought everything was ok, today I was exploring through tuner & went to check diagnostic's in menu & this p0480 code was there? Current operating oil temps seem to be in the 190's-203 as of today, with coolant ranging anywhere from 3-6 degrees of oil temps. I am a DIY'r and any assistance would greatly be appreciated.
Will all trouble codes go through tuner now, instead of instrument panel? or will codes that are really troublesome still show up on instrument cluster?
