Ok so I picked my truck up after getting timing belt, water pump, all seals and belts and now my check engine light is on. Picked it up after hours so couldn't ask my mechanic about it til next week. Going to try a reset when I get home. Haven't received my Ultra gauge yet. Any thoughts?
CEL Light After Timing Belt?

Don't reset it! Take it to Auto Zone or Advanced and have them scan it for free and write the code down and report back

On the P0340, that's definitely something they could have screwed up doing the TB. There is a connector through the upper TB cover low down on the left looking at the engine from the front. Here is the sensor itself, pointing at the pulley right where the white timing mark is (see arrow):
Check the connector on the cover. If that that's not it, take it back to the mechanic who did the TB. If it runs OK, you can drive it. (JD90--it's a sensor issue, not the actual position of the camshaft itself.)
For the P0100(MAF) and P0110(intake air temp.) check the connection to the MAF sensor on the air intake. Both those sensors go through that plug. They would have had to mess with that, too. Bozos.....

They very well may be off a tooth or two...I had the same trouble codes when my belt jumped before I did the service.

P0340 sure....but P0100 and P0110? I can't see how that would happen from a jumped TB. I am not saying you are wrong but I would love an explanation if anyone has one. TB is certainly not listed in the FSM as a possible cause for either of these.

Ok looks like maybe I take the cover off to see/get to that connection? Can't quite tell

Ok loks like you guys are on to something. Took a look and sure enough no connection. Can't tell but maybe this might be the connector (in second pic to the right of my thumb). Also found the wire that goes into the connector I believe, just hanging loose (also in scond pic - why the heck is this just hanging loose!) Could this throw all of the afore mentioned codes?
Thanks

Well, for sure it's the P0340. That's exactly the kind of thing I thought you would find. It looks like plug and connector got ripped off. Is the black thing by the thumb connected to a wire that goes behind the cover? Are both halves there? By rights, it's your mechanic's problem. Or, you might want to take the cover off and see where the sensor's wires lead and if the other half of the connector is loose inside if it is not outside. (Kudos to kball for that pic, I was looking for one like that and couldn't find it.)
My opinion is the P0100/Pp0110 is a separate f-up. Did you check the MAF connector on the airbox? I think these are pics from a '98-'98:
However, sensor issues can be funny so if the MAF connection looks fine I would fix the CamPos connection and see what happens (if you are going to try to fix it yourself). Since YotaZach says they came together for him they might disappear. I just don't comprehend the logic but that does not mean it's impossible.

Thanks all. The details and pictures were VERY helpful. Love this group! I'll run this back to the mechanic to let him deal with as I agree it is clearly their screw up. Will report back....
Oh and the MAF looks ok. A slight gap at the airbox but believe that was there before.

Hard to tell from your pic but that plug next to your thumb may be the one coming off the bottom of the power steering pump. Your mechanic may have left several things unplugged...

You're right, I fried my MAF when my belt jumped. I swamped mine and the belt jumped because the crank sprocket was packed with mud.
What I had to deal with:
Holy smokes! That looks a mess!
UPDATE: Dropping it off in the morning at the mechanic's. He said they will take care of it and make it right. I don't know what all has to be disconnected for this job but I'm going to take another look around tonight and see if there are any other visible stray connections.

Volley,
If your mechanic unplugged the power steering connector, make sure the connector for the AC compressor is plugged in (it sits right on top of the compressor).
That engine has seen cleaner days. I am amazed that the pedal and cruise control cables moved at all, if they did.
