Question
P1345 says Crank and Cam position sensor correlation. What does this mean? other than they are not in correlation. I have been to mechanic, he hooks up "machine" to correlate them, yet check engine light/code stays on even when his computer says they are in synch. Do I need to replace Crank and/or Cam position sensors?

If the 'adaption re-set' has not worked then you have another problem. I would look at the data stream from the cam and crank sensor make sure that their ratios are correct, make sure that the cam retard number is 0-3 degrees and no more. if it is then check the distributor, if there is play in side on the reluctor wheel, then a new distributor is needed. if still no luck then do a timing chain slack test, if the timing chain is too worn, it can throw off the cam/crank timing. if the above 2 tests turn out really well, then I would first replace the cam sensor, because if the crank sensor goes bad it will usually set its own code, I believe that this is an OEM code 35 on GM. lastly replace the Crank Sensor.

TY very much. Seems you may be right on after all of the research I have done. Again, I will let you know how it goes this weekend.

After allot of trial and error; the only solution I found was to simply replace the DISTRIBUTOR itself. Very easy to do with a cap, rotor, CMP sensor & Distributor already put together. Very simple.

Answer #2
I am puzzled as well. I have a '98 silverado with 5.7L. It shows the same code. I have replaced the timing chain, distributor and crank position sensor. It still shows the same code after clearing several times and continued driving. LLMF
