BigAl Posted April 7, 2009 Share Posted April 7, 2009 Well my little $300 GL 4x4 project beater is almost road worthy, but I need to get the CEL taken care of before she will pass emissions. The list of work I have done is extensive, but the basics on the engine work are air filter, oil change, plugs, fuel filter, PCV, plug wires, 44K fuel treatment, coolant flush, temp sensor and drive belts. So she runs pretty damn good now aside from the low idle (400-500 RPM) and the god awful TOD, but I still have the CEL keeping me from getting through emissions. My local Suby gurus (Super Rupair in Boulder,CO) told me that I could check this by connecting the "d-check" connectors under the dash, driving until the CEL comes on, then pull over and check for a blinking light under the dash on the drivers side. Only problem is, they didnt have a list for what any of the blinking sequences mean. So now my question is, does this sound accurate, and does anyone have a list of what these blinks mean? Thanks in advance. Link to comment Share on other sites More sharing options...

BigAl Posted April 7, 2009 Author Share Posted April 7, 2009 Wow, that is exactly what I needed. Thank you!! Link to comment Share on other sites More sharing options...
BigAl Posted April 13, 2009 Author Share Posted April 13, 2009 Ok, got the codes pulled, thanks again for the help. Got 2 codes off of it. 24 - Idle Air Control Valve 34 - EGR Solenoid The EGR solenoid is only $50 online, and I can have my shop get them cheaper, not a big deal. But the average going price online for the IACV is $300 Cheapest I have found was eBay at $150. Anyone know of a good way to test or rebuild this guy or maybe a cheaper place to get them? I only paid $300 for the whole car, I am gonna have a hard time throwing down the same for a friggin valve. Thanks again guys. Alex Link to comment Share on other sites More sharing options...
Cougar Posted April 13, 2009 Share Posted April 13, 2009 The codes also mean there could be a fault in the circuit to them. Have you checked to see if 12 volts is getting to the solenoids or checked the resistances of the coils to see if they are open? If the coil resistances are ok then you may have a circuit fault to these solenoids. You may have to place the ECU in the test mode to check the voltage too them as I don't think they are on all the time. Link to comment Share on other sites More sharing options...
BigAl Posted April 13, 2009 Author Share Posted April 13, 2009 I actually haven't checked that yet, I will get a voltmeter on it this week next time I am at the shop. Thanks for the help. Link to comment Share on other sites More sharing options...
ivantruckman Posted April 13, 2009 Share Posted April 13, 2009 you could try pulling them and give them a thorough cleaning Link to comment Share on other sites More sharing options...
