intermittent CEL p0443
So I'm back on the jeep scene with a 99 xj 4.0. The check engine light wasn't on when I went home with the jeep then I got home. I get that p0443 refers to evap solenoid. I checked voltage at the pig tail and got 13 volts on one terminal and 4 volts on the other. Is that normal? Then does the evap canister open atmosphere vent behind the trans dipstick? Because I smoked the evap system and it was dumping there. Then with the solenoid plugged back up it ticked with about a half a second or so between ticks. So I smoked that too and it is in fact opening and closing at that half second interval. I'm at a loss for why the hell this is throwing a code other than open air venting behind trans dipstick.

Evap Solenoid
If your evap solenoid gets dirt/dust in it it will not seal/function properly causing the code to be thrown, a dirty vent filter will cause the solenoid to get contaminated, recommend replacing filter with solenoid, check lines for cracking too common problems
