My 2001 Miata is giving a P0010 code. I took it to the dealer and they didn't find anything wrong. Here is a synopsis of the info on the work order:
< Scanned for codes, P0010, No TSBs found, check sensor resistance ok, 7.0ohms, checked sensor input voltage, ok, 13.3 volts, checked signal, ground appears ok, could be internal oil control valve or PCM, performed several tests which implies that cam is work normally, could be an internal problem with PCM or OCV or an intermittant wiring continuity problem between PCM and OCV, cleared code, road tested, light did not return>
When I got it back I got about 12 miles before the light came back on.
Anyone know where the needle in the haystack is?
