95 Wrangler, 4 cyl, 5 spd. Oil pressure gauge doesn't register, so I figure either the gauge or the sending unit is bad.

Question 1, if the sending unit is bad, wouldn't the check engine light come on since no oil pressure is registering?

Question 2, is that the sending unit located right behind the alternator?

Thanks guys.
