well I got this strange problem, my engine fan is running at high (very high) speed. now I know this is a fail safe for temp/overheating issues. I have a diagnostic tool (scanner/reader tool) the strange thing is I have replaced Engine Coolant Temperature (ECT) Sensor and the Radiator Outlet Temperature Sensor (thermostat with sensor) also I have checked shorts to these sensors (all good). now when I do a code read all codes are gone, I am able to clear codes and permanent code that only the computer can clear when happy is cleared too. but sometimes the codes (P00B6 CODE) come back till I clear them again. oh and I have also pulled the negative cable of he battery to try to reset computer...o go ;o(
I have to pull out 2 of the relays (out of 4 relays) just to slow down my engine fan so I don't burn out the fan motor.
