I was wondering if its possible for a Mazda 3 2011 AT car to function without ECU? The reason I am asking is
- When I start the engine, the CheckEngineLight doesnot come at all
- When I took my car for scanning, they informed me that Port has been disconnected, and they assumed that ECU has been removed
I am taking my car to Mazda service tomorrow for a through check however if the ECU is to be replaced what is the cost am I looking at?
Also is AT sensor somehow connected to ECU or is it a separate one, the reason being when when I move the key to second position the AT light appears and disappears after the engine is started.
My Car Specs are Mazda 3 1.6 Gasoline AT 2011
