ShawnW Posted November 2, 2006 Share Posted November 2, 2006 Does anybody know what this code means or what part it refers to? ECS light comes on when the car is all the way warmed up and after driving a certain amount of time but I havent figured out how long just noticed its about the same amt of time each time.

GLCraig Posted November 2, 2006 Share Posted November 2, 2006 my FSM Show 52 being "solenoid valve remains on". There is also diagnostic flowchart in the Emission Control section of my FSM. I can try to scan it if you need me too. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted November 2, 2006 Share Posted November 2, 2006 It's a lot like the EGR and Purge solenoids of the SPFI system - it will look just like them and it's somewhere on the manifold. There are probably a couple of them. Also, is this an EA81 or EA82? The feedback systems are not the same between the two. GD Quote Link to comment Share on other sites More sharing options...
ShawnW Posted November 3, 2006 Author Share Posted November 3, 2006 Ea81. And any scan you can provide would be wonderful. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted November 3, 2006 Share Posted November 3, 2006 52 is solenoid valve 1, which according to my FSM controls the ASV(s). There are either one or two vacuum operated air suction valves comming off the spacers under each head. If you follow the vacuum supply line from one of these it will lead you back to solenoid 1. You can replace it with one from an SPFI soob or I hear the toyota ones are good too. Or a resistor should get the code gone. The ASV's aren't needed for proper operation and they tend to fail and suck junk into the carb anyway. GD Quote Link to comment Share on other sites More sharing options...
