No power?

Hi,

You are correct about the exhaust leak. It won't cause it to go into limp mode. In this case, what you need to do is have the can-bus scanned for diagnostic trouble codes.

CAN stands for controller area network. Basically, all the computers/modules are tied together via a few wires. This type of scan will retrieve diagnostic trouble codes regardless of the module storing them.

Here is a link that explains how it's done:

By chance, have you had this done? You indicated two cam sensors being replaced. Did you have codes that indicated a problem with the sensors?

Let me know.

Take care,

Joe
