Error Code P0173-Fuel Trim Bank?
I got two error codes, P0173 and P0125. I thought the cause of the P0173 was the P0125. However the ECT is fine, and I just replaced the thermostats, coolent is full.
So now I'm guessing its the P0173 causing the P0125. Autozone can't tell me what a P0173 is for a mitsubishi is. However, for a Kia its a problem with Fuel Trim Bank 2. Whats a Fuel Trim Bank?
