Hey everyone, my Ford expedition went in for a timing chain job and it came back with some cooling fan error codes. Namely (p0480 and p0528) cooling fan control circuit and cooling fan speed sensor. All my connections seem to be fine, my relay clicks in the box. I have a bidirectional scan tool (xtool Anyscan A30M). What do I do now? I hate to shoot the parts cannon but I also don't know if it'll be worth replacing the relay and seeing if that works. I also haven't been able to locate the speed sensor in particular. Any advice? Thank you very much!
Btw, that shop closed its doors after the mechanic had a heart attack. He's just fine but he retired.
It sounds like whoever did the work disconnected or messed up the wiring on the fan circuit. Check all connections for tightness and look for disconnected wiring starting at the fan and working backwards, before spending money on a new relay or other parts.
