P1620 (MAP Cooling Control Circuit Signal High)

[whattingh]

So just a a checkup I check for codes the other day and found P1620 (MAP Cooling Control Circuit Signal High). So I reset it and few days later check codes again and it there again. My temp gauge is not 100% middle, it sits just a little to the hot side.

It something to worry about? do i need to replace thermostat ASAP?

Ok so today I finally got time to check the resistance of the thermostat. It gives 1.6ohm. But I have no idea what is the correct range. Do anyone know what is should be?
