91soob Posted November 9, 2009 Share Posted November 9, 2009 I have a 1991 loyale 1.8 and was wondering how to check for codes? My CEL turns on when it warms up and seems to be slower as soon as it turns on, any help would be awesome, Thanks Link to comment Share on other sites More sharing options...
GeneralDisorder Posted November 9, 2009 Share Posted November 9, 2009 Remove the kick-panel under the driver's side of the dash. Drive the car till the lamp comes on and then read the codes flashed from the ECU's red LED. Probably O2 sensor, EGR/EVAP purge solenoid code's......

91soob Posted November 9, 2009 Author Share Posted November 9, 2009 Thank you, i have heard alot of similar problems but it is always when their cars are cold,(mine is warmed up then it does it)wierd huh? Link to comment Share on other sites More sharing options...
GeneralDisorder Posted November 9, 2009 Share Posted November 9, 2009 O2 sensor's only begin reporting when they have reached operating temp so the ECU will wait for a signal and if one never comes or it's way out of range.... up pops the code. Also if the coolant sensor should fail and only report that the engine is cold - that would cause a similar effect. Although they usually fail hot - telling the ECU the engine is warm when it is not.

91soob Posted November 9, 2009 Author Share Posted November 9, 2009 i cant seem to find the led light that flashs the codes, is there anymore detail you could advise? Thanks Link to comment Share on other sites More sharing options...
GeneralDisorder Posted November 9, 2009 Share Posted November 9, 2009 The big silver box (~8"x6"x2") bolted to the steering column. You have to remove the kick panel to see it. The LED is seen through a window in the side of the box. GD Link to comment Share on other sites More sharing options...
91soob Posted November 13, 2009 Author Share Posted November 13, 2009 I found out it was code 34 witch is the EGR solenoid. cant find a solenoid tho:mad: Link to comment Share on other sites More sharing options...
GeneralDisorder Posted November 14, 2009 Share Posted November 14, 2009 Replace the solenoid with a 33 Ohm, 5 watt resistor. That will permanently fix the problem. You don't need the EGR solenoid. GD Link to comment Share on other sites More sharing options...

GeneralDisorder Posted November 17, 2009 Share Posted November 17, 2009 At the bottom of my SPFI conversion document, there are links to the EA82 FSM sections dealing with the SPFI and all the diagnostic codes. Download them and you'll have all the information you need: http://home.comcast.net/~trilinear/EA81_SPFI.html GD Link to comment Share on other sites More sharing options...
