wintergreen Posted November 23, 2018 Share Posted November 23, 2018 Is it possible to have a "bad" connection some where that would drop voltage to a sensor causing a false CEL? If so how would one go about finding and fixing such a problem? Best place to get PDF wire diagrams for a 3rd Gen legacy? Link to comment Share on other sites More sharing options...
08SpecB_DE Posted November 23, 2018 Share Posted November 23, 2018 Loose terminal tension can cause intermittent issues. What code(s) are you getting? Link to comment Share on other sites More sharing options...
wintergreen Posted November 23, 2018 Author Share Posted November 23, 2018 P1494, P1496, which are both EGR and there isn't an EGR on the engine. Also P0328 knock sensor. I only have 3.1v when I back probe the knock sensor sub harness with or without the sensor plugged in. This isn't right, unplugged reference should be 5v and plugged into a functional KS should be 2.5v. Link to comment Share on other sites More sharing options...
