Hello everyone,

I added a "manual" clutch fan switch to my truck, simple switch that manually engages the engine fan if I desire when my tranny temps are high / I am starting out on the highway with a load and the temps typically climb at low speeds / getting up to speed.

Yesterday I did the key on / off / on / off to pull the codes and P0480 popped up which from a quick search that it could be the engine clutch fan.

Will I pull a code since I am manually activating the fan?

I tried my switch the other day and it did not seem to engage the fan.
