Crankshaft and Camshaft Position Sensor

I am getting an error code which indicates intermittent failure of either crankshaft or camshaft postion sensor (1997 tj). I have determined how to change the crankshaft sensor, but don't know where the camshaft sensor is located, or how to change it.

Has anyone done these repairs, and is there anyway to check the sensors to see if they are indeed bad? Best price I can find on crankshaft PS is $120, and I hate to replace it if it is o.k. Thanks.

The factory service manual states both should be checked with a scan tool. A voltmeter can check power at the very least but not tell where the problem is in the circuitry.

The camshaft sensor is located inside the distributor, underneath the plastic plate you'll find if you lift up the distributor cap. What symptoms are you having? $120 for the CPS??? Wow, I think I paid under $80 for mine which I carry as a spare since they are known for going out... eventually that is.

Guys - thanks for the responses.

Gerry - I plow snow with my Wrangler, and after plowing for an hour or so I start to get a stalling symptom, won't take the gas, surges from around 700 to 2000 rpm, acts like it isn't getting gas, then check engine light comes on. Let it sit turned off for about 10 min. then it starts and runs o.k. again.

It has done this about 5 times over the last 3 days, and now I sense a slight ongoing miss at driving speeds.

The engine code comes back as 12, 11, 11, 55. The 11 being intermitten camshaft or crankshaft sensor.

Yesterday I changed plugs, wires, cap and rotor. The plugs had burned the gap way to high, and needed replacement.

Any additional recommendations?? Any way to test the sensors? And where can I get the CPS for less? The $120 price was at autozone.

Thanks for additional help.

I bought my CPS from the dealer but then I always get good pricing from the dealer's parts department staff. I have a carefully cultivated friends-type relationship with the guys behind the parts counter so I can twist their collective arms. If you ask for a "better cash price" maybe they'll sell it for a more reasonable price... but ya gotta ask.

I wish I even had a gut feeling for whether the problem is the crankshaft or camshaft position sensor but I don't. The camshaft position sensor will be a lot easier to change, that is for sure. But then the crankshaft position sensor is the one that is really exposed to the elements... if I were to make a WAG (wild-a$$ guess), I'd probably lean towards the crankshaft position sensor as the culprit... but that's just a WAG.
