May 2, 200619 yr The new,1990,Legacy is throwing 2 codes. knock sensor and purge valve. I found the knock sensor under the throttle body but cannot find the purge tank selinoid. Anyone help me out? I did some yarding today for it and got a rear hatch for $10.00 today. I also found a few knock sensors but all were cracked. I'm sure those are no good. Thanks all!! Mark
