I got a engine light and pulled P00B7. Coolant tank was low I topped it off. Gauge reads fine. Fan does seem loud than what I'm used to but I've never paid attention to it till now. No visible leaks I can find. Anyone have this before?
Engine Coolant Flow Insufficient. The difference between the Radiator Coolant Temperature and the Engine Coolant Temperature is too high. Seem like low coolant could do it. The manual also mentions a thermostat that's failing or resistance in the Radiator Coolant Temperature sensor.
I have the same Error code.... the fan would come on when the car was first started and would stay on for some time. What was the result of this after you brought it to the dealer? did you just need to fill the coolant or was it worse?
