hey everyone i have an 89 toyota pickup with a 3.0 v6 and i just had the knock sensor replaced, and the short intermediate that goes through the intake manifold, after this the ecu still says code 52 knock sensor circuit, so we decided to go and run jumper wire from the ecu (i know we got the right pin we took the cover off and found the knk pin)to the knock sensor and the light still goes on for the same problem, i have heard some thing about an egr valve causing "knocking" but i'm not to fimilar with toyotas, any help would be great.
