Angry Ecm not grounding some relays

It started out with my ac high pressure valve releasing pressure. Having gone through this issue before, I immediately checked my cooling fan. No voltage there so I checked my relays for both high and low speed and the relays are fine. Then I bypassed the high speed relay and my fan works.
Later, I get a CIL and the codes are P0480, P0481, P0645. After checking fuses and relays for both fan speeds and the ac relay, I found out that the ecm isn't sending ground to those relays.
I have a 2005 pt cruiser touring edition, no turbo, but the temp sensor is mounted like it's the turbo motor.
Could the ECT be bad even though the temperature gauge is still working and I don't experience engine problems?
