jonlabree Posted September 3, 2012 Share Posted September 3, 2012 I know that Eo43 refers to the Electronic spark control. But What could be the problem? Link to comment Share on other sites More sharing options...
Guest Mc_Reatta Posted September 3, 2012 Share Posted September 3, 2012 Problem with your knock sensor. Check that wire is connected to it. Can check sensor and circuit with a hammer and a DVM.Tests are on page 8D1-55 in the 90 FSM. Basically just checking the resistance of the sensor and the voltage from the ECM.

jonlabree Posted September 3, 2012 Author Share Posted September 3, 2012 That's strange because the knock sensor is new this spring. Link to comment Share on other sites More sharing options...
