Taylor Westhead Posted September 13, 2013 Report Share Posted September 13, 2013 For the last couple of months I've been getting an engine light problem (been coming on and off randomly) and found out it was the knock sensor. So I replaced it with one off a 20v I had lying around. All works good except it runs quite rich and I've had to adjust the idler screw to stop it stalling (or shuddering) after I've given it a bit of revs. Would anyone have a solution to this? I never had this problem until I replaced the sensor. Any help will greatly appreciated :-) Quote Link to comment Share on other sites More sharing options...
LittleRedSpirit Posted September 13, 2013 Report Share Posted September 13, 2013 Use toyodiy to compare the sensors. If they are the same then you have other issues, it may well send the ecu into limp mode if the 20v one is different. Quote Link to comment Share on other sites More sharing options...
Mechanical Sympathy Posted September 13, 2013 Report Share Posted September 13, 2013 Indeed have you tried re-fitting the original sensor? Quote Link to comment Share on other sites More sharing options...
Taylor Westhead Posted September 14, 2013 Author Report Share Posted September 14, 2013 Would it be possible that another sensor shit itself coincidently. Maybe the o2 sensor? Or making it misbehave? Quote Link to comment Share on other sites More sharing options...
Taylor Westhead Posted September 14, 2013 Author Report Share Posted September 14, 2013 And I can't refit the original sensor, the plug on the sensor came off whilst removing. Which was probably why it was misbehaving in the first place. Quote Link to comment Share on other sites More sharing options...
