I posted this in the general questions area, but think I posed in the wrong section -
I haven't seen any topic on this so here I go. Currently I have the infamous 'service engine soon' light on. Paid out some $$ and had the local mechanic pull the codes. Of course - its the camshaft position sensor fault. HOWEVER - I have a '95 Mustang 3.8L V6 with a build date of 6/95 on the door pillar. The issue at hand is this: The mechanic said he had to triple check because this car should have a OBD I computer, yet spits out a p-code of 340. He states it has a OBD II system, when it should be running with a OBD I. I am the 2nd owner and just got this car 1-1/2 months ago. Should this be any concern or is this ok? Was it built like this from the factory ('96 computer in a '95)? I do know that the Autozone CPS sensor is too small in diameter for my car. The dealer wants $83 as he stated there are 2 different sensor possibilities. Let me know some feedback on this topic. Might I find other '96 model parts in my '95 or should I call it a '95-1/2?

 

some 95 cars of various brands had OBD II

generally 96 and up is accepted as the start of OBD II but some 95's exist
