Can't get timing cover off, part in way

Been trying to get my timing cover off. There is a sensor in the way that doesn't allow the plate to come up over the studs in the block. I pulled the oil filter to get a better look. There is one wire that comes out the end of it, the wire goes in under the intake manifold and connects in the middle. I can't imagine I have to pull the intake manifold to get to the connection to properly remove this sensor to check the timing? It seems that if I thread the sensor out it will end up twisting and possibly breaking the wire.

I thought it was odd too, doesn't make sense that the timing mark access be boxed in. There is only about 3mm between the cover and the sensor, and both studs are longer than that. I couldn't get access to the connection in the valley, may have to use a couple extra long needle nose pliers.

 

Appreciate the input everyone, I think we've found a winner. These cars are know for all the bad connections, I can't see any reason not to add another. I've done this before, but in this case it didn't occur to me, thanks and now I can sleep tonight.

Rick, I used to live in Sac, spent 15 years there and wish I could get back. Thanks again for the suggestion.
