97 Tahoe...Rebuilt Motor....Sensor Questions

[Biggwaukegan]

Guys its been awhile. Nice to be back. So heres my issue. Getting ready to install a rebuilt motor in my 97 hoe. But I think Im gonna have to relearn or reprogram the camshaft and crankshaft sensors right? How and where do I go to have this done? Can I wing it myself or do I have to go to Chevy dealer? thanks

I think it needs at least a tech II scanner?
I ended up getting mine done for $50 at a dealership.
I had to have that relearn done with my new BB PCM, not with my new motor?
Unless your changing computers, do you have to do that?


EDIT: Good to see that you didn't sell your truck and it's going to be back on the road!

wont need to relearn unless u program the computer or swap it out

Really? not even the crankshaft or camshaft sensors?

 

[lowAZhoe]

well the camshaft sensor is technically the distributor....u just need to make sure that it is timed right. and the crank sensor, the computer doesnt know if its a new sensor or new engine...
