I noticed this weekend that both of my radiator fans are always on (possibly full speed) when the car is in on/run mode - both with the engine running or not. What should I be looking at to fix it?
I've tried messing with A/C controls, as apparently having the A/C or defroster on can kick the fans on. I believe the engine temperature sensor is working properly, so it's not thinking the engine is too hot and kicking the fans on to try to cool it down. Although my AiM Solo 2 DL doesn't pull the ECT data, but my RaceCaputre Track mk2 does (weird). I also pulled each of the 3 Fan relays under the hood, which resulted in one fan running and one fan not running in each of the 3 cases. So, it seems the the relays are fine unless all 3 of them went bad at the same time.
Car is 2013 BRZ limited with 45k miles and at this point is a weekend / track car. The car has been sitting in the garage for the past 6 months and I'm starting to get it ready for a track day end of the month. Stock ECU/tune with no electrical mods and stock cooling system (radiator and fans).
I also have ABS/traction control/engine lights on due to a faulty left rear wheel speed sensor, which I probably broke installing extended wheel studs over the winter. I have a replacement on order and will get that squared away as soon as possible. I checked the OBDII codes via Torque and just seeing the code for the wheel speed sensor (P0500).
Attached image of my wheel speeds: 2290.6mph... almost Mach 3!
