I would like the answer to that as well. Mine runs like a clock with it unplugged. Long ago some believed that unplugging the sensor which kicks the system into batch mode would provide additional fuel so they put a switch in the wire to cut it off rather than having to unplug it. Once in awhile, someone posts that their car runs badly when unplugged but I have not seen an explanation.
More than once, I have seen cars run better when unplugged and replacing it cured the problems experienced when plugged.
Beats me.. dunno I guess I'm only good for negative responses today.
First, at the risk of one of us looking stupid, are you sure you're unplugging the cam sensor? Describe what you're unplugging. If it is indeed the cam sensor, I'll hazard a guess and say it's the chip or the ECM (anybody know where the back-up batch fueling is in the code?)
If it runs fine otherwise, I would ignore it and be happy. yup
