Hello, Eddie here and I will do my best to help, have you tried another cam sensor yet by chance? drivers side back of the exhaust cam.

Customer: replied 1 year ago.
I replaced that about a year ago with a brand new one is it likely to go again that soon?
Customer: replied 1 year ago.
I had a similar problem then and replaced cam sensor, crank sensor and coil. What is the method to test the cam sensor?
Expert:  Edward replied 1 year ago.

hmmm.. I don't know, You would think they would last longer. You have to have a scope to check them, or advanced type Volvo VST scan tool. any codes setting? I believe you can ohm them out, but I'm not positive on the method, I would have to look it up. That one is OBD II first year 96, have you tried to check codes yet by chance?

Does the check engine light go OUT when cranking or does it stay on?

If that is the one you mean it does not come on at all
