Hi...I pulled the codes from my 95 90fwd, and 2113 was the result. Over the last couple weeks, it's been running rough--intermittent spark from center coil, and now I'm getting no spark at all, from any coil. This came after I replaced a perfectly good coil pack-thinking that was the culprit(it was firing with the new one, as it had before). Before I run out to buy a new cam pos sensor, does anyone know what I can do to test the sensor? ie ohm test-which terminals, etc.
Thanks

If you want to test, you need to fake it using a power supply to two terminals, and monitor the 3rd terminal to ground as a piece of metal passes past the sensor.

...for 2 live with ignition switch on, and one good ground out of one of the terminals? I'm just trying to rule out faulty wiring before I drop another 80 bucks

You could probably do that... but I make no gaurantees it'll work. I've never done it.

any thoughts on $80 + tax being a reasonable price for a replacement sensor?
