The car is still running normally but the dealer, after doing some initial diagnosis, said a code stored P0100 and recommended to replace ECM and MAF sensor. I don't think the shock of hitting a street bump was strong enough to short or cause the ECM failure so that it has to be replaced. Before the incidence, I did open up and use MAF cleaner to clean the MAF sensor but for months there had been no engine light on until I hit the bump. Could someone give me some advise on this?

If you have a P0100 code I would recommend checking the wiring to your MAF sensor first. Make sure it is fully plugged in and all the wiring looks good, no exposed wires, etc. If the wiring is good you will more than likely need a new MAF sensor. As for the ECM, I would definately question the recommendation for this especially only going off a P0100 code. Usually with ECM failures you will see many random codes for several components, because of how many components are controlled by the ECM.
