Cobalt rental car

[cmitchell17]

Someone hit my truck and their insurance company gave me a 08 cobablt 2.2L and I accidentally backed up over a concrete ledge and it looks like it hit and dented in the cat a little. The problem is the check engine light is on now and it won't go away. I can hear a small rattle sound which I don't know if it broke the honeycom stuff in the cat loose or what?

I can connect to it but cant check or clear codes I guess becuase its a hitachi ecm. Is there anything else I can do to check the codes? I dont see how I could of messed up the cat that much so I just dont want to rental company make me pay 1000 dollars or something for a new cat which I thought was covered under a 100,000 mile warrenty or something?

In the scantool, select the ECM type as an E38, you should be able to read and clear codes no problem on that Hitachi ECM.

It will connect but most of thebuttons and the codes buttons are greyed outwhenever I try to read thepcm it says please select a valid ecm type.

when I backed over some thing in reverse it pushed the exhaust systemtoward the engineand put a small dent in the cat so I think that is what is rattle ing but I don't no why else it would their a code?

On the console thing it just says its trying to detect ecm and tcm and says its not detected it will still connect and let me log but it dosent show anything. I was just trying to get it to connect and the car was at idle and within a couple minuets the car just slowly started to idle down and it just died?

FlashScan V1 does not support that vehicle.

Ok that makes sense now thanks, anyone know if the cat gets a dent in it is it that sensitive to pick up a catalyst efficientcy problem if thats what the code is?

[cmitchell17]

so it turned out to be a heated O 2 sensor code p0030 I guess there is only two o2 sensors so I guess the impact just broke a sensor because I can't see where a write would be broken
