Code 31 - ZR-1 Net Registry Forums

mmkkpro · 05-10-2020

Good morning guys, I am having an intermittent code 31on my 1990Z, it doesn't seem to affect the way the engine runs other than no secondaries. When I unhook the battery ground it goes away and runs great. I checked the FSM and for intermittent says to check section B.
I checked Jerry's, and he does not show a listing for a cam sensor, would you guys know where to find one? Part seems to be superceded. Something about new part has wrong shield. Can old shield be used on new sensor maybe?
I just got done cleaning connections and I'm going on a drive now, see what happens, thanks for any info.
