First post would like to say hello to everyone here. So I have a 02 eclipse with 3.0 and about a mouth back I had to change the crank position sensor. and it started right up and ran fine. Three day ago it shut off again code scanner says PO 335 crankshaft position sensor malfunction circuit A . The first time it happen scanner only said crankshaft position sensor malfunction .It did not say anything about circuit A . Can anyone tell me what circuit A is ? I don't want to waste my time and money on something I just replaced.
