I had all of my sensors replaced under the p2098 and p2096 code but my car is still pulling a p2098 code...

The dealer replaced them under my warranty. The dealer claims that it maybe an electrical problem but who knows what that can mean. Anyone have any ideas what it can mean...

I replaced a crankshaft sensor, electronic control module and secondary air pump about 6 months ago.

Any advice would be greatly appreciated.

Thanks
