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 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?

I have a 94 Gt they came equipped with the OBDII ports but they are barely functional. you have to use the OBD I in order to run your system through the Diognstics check.

I dont think the 95 mustang had the cam shaft position sensor. You could still manually advance the timing on the 95 Mustang. I think that first came out on the 96 Mustang with the 4.6 engine. I do know a 96 computer will not run a 95. I am thinking who ever you bought the car from, put a 4.6 engine in a 95 Mustang. I could be wrong though. Does the intake manifold say 5.0 on top of it?

This has a 3.8L V6 in it - with a OBD II port just above the gas pedal below the radio. I checked and there is no plug-in for the OBD I (which I have a tester for) in the engine compartment. There is a camshaft position sensor under the distributorless module (p/n E9SE-12A112-AA). From the mechanic, the codes came out as a P0340. I did try to trace this and found that I have only 3v (no pulsing) on the data line, which doesn't change as I rotate the engine 12v and gnd are ok. Hopefully, just replacing the sensor will be fine and fix it. This however, doesn't answer the computer question of is this a half '95/half '96? - and hopefully isn't really an issue. I did check ALL body panels and all the serial numbers match the plate on the dash. SO - not a '96 re-plated. I can't see anyone in their right mind actually tearing one control system out and installing another. Looking at it all, looks original. Thanks for the replies as this has my curiousity rolling....

V6 Mustangs were equipped with ODB-II starting in 94, so there is nothing out of the ordinary with your car, including the sensor (also on at least as early as 94 models). The ODB-II first showed up on GT mustangs starting in 96 with the 4.6L engine.

I too had a check engine light and found a P0340 code. I removed the Can position sensor to find the vane on the syncro bent and holding the broken piece of the sensor. The sensor did not exhibit any voltage change as the engine turned. these engins do run without a functional CMS!! Someone had advanced the rotaition of the syncro as far conterclockwise as possible. After replacintg the syncro the engine misses under load, no trouble codes displayed. Is it possible I have the syncronizer installed out of position by 1 tooth?
