Thermostat Malfunction EJ25
I have a MY01 2.5RS.
CEL came on couple days ago when I was driving down the Hwy. (I was probably going 85~90 mph)
So, I pulled the code w/ OBDII scanner, and it's P1490; Thermostat Malfunction.
I am not sure where to go from here. Is this mean I would have to replace the thermostat?
I have a ProECM Powerchip; is this could be a possible cause of the problem? After I installed the powerchip, I don't think the cooling fan turns on anymore. Even when I turn the A/C on while idling, cooling fan stays off.
Some help/comments would be appreciated. thanks.
