Do you have a 4cyl or V6 engine?Not sure what the letters mean but if I get a little more info I can help you out.So why does it need a TCM?

That's the only code you have?Does it run rough at idle and down the road like you have a engine miss?

It does say reset the code ad if the code comes back you have a bad to replace the tcm.Not sure what years will work if you get a used tcm make sure you get it reflashed at the dealer.
