I replaced my evap solenoid with a factory number replacement from Bosch. Checked the codes, erased them and it seemed to work as the light stayed off for a while. A week or so after (not too many miles driven, maybe 15 or so) the check engine light came on again for the same item I thought I fixed; P0441. So I erased it again drive about 10 miles, light stayed off so far. How do I really check this device to know I really fixed it or am between drive cycle testing?
