I have a 2003 Cadillac Deville that has error codes that will not clear. It can not pass inspection and over 200 miles have been put on it in an effort to clear codes to pass inspection

Yes. You're good

Cadillac codes are easy to read..then replace the bad sensors etc and then clear the codes and try again etc

Hi there:
DTC P0340 - CMP (Camsahft Position) Sensor Circuit Malfunction

CHeck details HERE.

Did you have the code cleared by a shop?

double check that the gas cap is the correct one and that it clicks 3 times at least when you put it on

You might have to go to a Cadillac dealership to get it reset. Some sections of the computer are locked out so only the manufacturer can fix it.

Yes you can. 2000 Cadillac should have a northstar already in it.

sounds like its related to the CAM SENSOR. Either the actual part or between there and the PCM. When you say the car was rebuilt, What was rebuilt ,the WHOLE CAR ? What type of warranty is there ?

E26 - Shorted Throttle Switch Circuit
E27 - Open circuit in throttle switch
On these 2 codes replace the TPS and clear codes (throttle position sensor).
E52 PCM/ECM Memory Reset
Have u cleared the memory? don't worry about this code.
