Re: Code P0480
DTC P0480 is a Cooling Fan 1 Control Circuit malfunction. This DTC sets when the PCM module output driver for that circuit fails the electrical integrity test. Meaning you could have a bad PCM module or maybe something causing a short on the output to Cooing Fan 1. Pull the Cooling Fan 1 relay in the main engine compartment fuse box, reset/clear the DTC, and then see what it does.
