Default Installed Injen CAI and got a CEL

The cell is PO605 which is:

- Open or short circuit condition
- Faulty ECM

anybody know what might be the cause? The car only has 6K miles so it cant be the ECM.

Of course you disconnected the battery before installing correct?

Reset your ecu yes, taking the battery out is a bit excessive.

This is a good idea when installing HFC/Test Pipes, Cat Back and intakes. The ECU recalculates to adjust to the new bolt on.
