I recently had my check engine light go on for a few days then off for a few. On and then off. Got an OBDII reading. Code was P-0170, something about a fuel trim malfunction.

I brought it back to the dealership and they said I need a new air mass sensor. IS this true? AMS is expensive. Only got 100,000KM on the car.
