obd2 code 430
 

just acquired an obd2 code reader and came back with this 430 code that relates to camshaft positioner sensor ,car runs fine ,bought it used a year ago and was wondering if maybe the dealership had repaired it and didn't remove the code,
If the sensor was bad wouldn't I notice it in the performance end.seems to have great power,no missing ,knocking, etc.

P0430 is a passenger side cat inefficiency code...

^+1.
The code for the cps is P0336, and the cps has no effect on performance, its there for misfire detection. Most likely you need a new cat, but bad cats are usually a symptom of another underlying problem (running rich, coolant in the engine, etc).

Looked at a couple of your posts, since you have an 02 and less than 120K the cat is covered under warranty.
