Default 2001 Check Engine Light is On

My hubby took my PT to Autozone and got the 0401 code for: check EGR. The guys there told me that it may be the EGR valve (which I can get from them) and/or it may be the Transducer (which I have to buy from Chrysler ).

Anyone know which is may be? Both? Do I have to replace both? Can I clean either of them?

I am assuming I will not pass the emission testing for my license plates until this has been resolved?

Probably just the EGR. Found this on PT (Pay site)..

P0401 (M) EGR System Failure - Required change in air/fuel ration not detected during diagnostic test.

The P0401 is a very common code for the EGR. More than a few have been replaced under warranty on the PT. A new valve should cure the codes. Make sure you follow the SM OE replacement instructions precisely. If you don't have a manual, you can find the OE procedure in the Pit area on the site. Once it's replaced, the code won't clear itself using the battery disconnect technique. Have the dealer clear it using their DRB scan tool during your next visit.
