...I lost my cam position sensor tonight...
P0340 Camshaft Position Sensor Circuit Malfunction
..:scratch:...Well, I lost all power on the freeway and a check gauge lite came on..Pulled out my scanner and got a P0340 code...
...Early 95 Ranger 2.3L but it is ODBII...Haynes says how to for all 2.3 except it has a small note on 95-97 only, something about the sensor on the oil pump behind the inner timing cover but can't find any useful info here or at TRS...How hard is this as I may have to pull the timing cover, timing chain, and an inner cover?
...Any help and diagrams asap am would be much appreciated...

...Update: From all the information I have researched and checking with the parts houses, you can buy a cam sensor and no one knows where they go on a 95-97 Ranger 2.3L as they are special..In Fact, I have also been told they do not have a cam sensor and I could not find one which leads me to believe there is none for these years...:scratch:
...If you have pics on the truck and info showing the 95-97 2.3L Ranger in fact has a cam position sensor, please post them here...

...I found the belt broken after reaching in to the top of the timing belt cover and finding the belt loose on the cam gear...
...This was a fairly easy process once you figure out how to remove the plastic timing cover..
..The most important thing when putting this all back together is finding and aligning all 3 "<>" diamond marks on the Cam, Crankshaft, and oil pump gears, as they are very fine marks and not easily seen...
...My gas mileage since I've owned the Ranger has never been better and it smogged the best it ever has since I've owned it after swapping this timing belt...These belts last about 60,000 miles but IMHO should be changed at leas every 3 years if not just for the maintenance and the fuel economy..
...I thought I would include these pics for future reference of all the parts in this area...
...The plastic timing cover removed..
...You can see the broken belt and how it has no tension in this pic...
...And I found it broke on the bottom at the crankshaft pulley/gear...
...The new and old belt..The new belt was 1/4" wider but the old one had many miles and suffered damage due to rocks and sand getting in the bottom of the plastic cover..
...There are 2 hidden bolts beneath the A/C that I had to loosen...Do not remove all the way as they are a booger to get started...Also, be careful of your power steering hoses at all times while doing this repair..
...The crank gear and pully...
...Misc. pics of this area...
..This is a good shot of the belt tensioner with the broken belt shown..
...These show the crank position sensor...

...Edit: Thanks to Rwenzing for sharing the diagrahms in post #8, the cam position sensor has been located..
...It is located behind the inner timing belt cover and the oil pump gear as marked by the arrow here...(View is looking from the ground up)...You do not need to remove anything to access this sensor as it is on the outside of the motor, drivers side, just above the oil pan...
