Re: Engine light check - Smog Check purgatory
Thanks Christoph ¨C I am still learning/looking for a solution. Do you (or anybody) know which pin from the ECU I need to find? According to what I saw on Busaru.com, it should be part of connector

Re: Engine light check - Smog Check purgatory
Hi Wayne. Thanks for your input. 1. Year of the 2.2: The engine is a 1990 ¨C 94 Legacy. I believe the builder mentioned mine was from 1993 (but I am not aware how to verify that) 2. Labeled CEL

Re: Engine light check - Smog Check purgatory
There would only be a trans code if the ecu is from an automatic. You can get rid of that code too by grounding the single wire from the ecu for the auto trans.

Re: Engine light check - Smog Check purgatory
All you have to do is run a wire from ecu to dash, power up an led with ignition and ground with ecu wire. if you read the kennedy EO label, they expect the light to be on with transmission codes.

Re: Engine light check - Smog Check purgatory
Just like Wayne says you need to run a long wire from the ECU CEL pin to the LED in the dash. You really want that also to check error codes. Just because the light is not on does not mean you don't

Re: Engine light check - Smog Check purgatory
What year 2.2? The ECU should have a CEL pin that should have certain voltages when on or off according to the pinout (Busaru.com) The CEL is likely wired through the black box upper left engine

Re: Engine light check - Smog Check purgatory
lol - Richard -a man of experience and wisdom! I¡¯ve been told that our local SLO referee has the equipment - and the authority to get me that mystical bar code sticker - to just complete the check

Re: Engine light check - Smog Check purgatory
It goes like this:? drive to your friendly Star Station, you say I need a Smog Check.? First question they ask:? What year is your vehicle?? You tell them, and they tell you:? "Well, our

Re: Engine light check - Smog Check purgatory
And here is my next line of thinking:? Referees "have" to have working equipment; yes, it takes a 2 stage appointment process to get in.? But 2 years ago when I sought the BAR sticker, the total

Re: Engine light check - Smog Check purgatory
Here is my theory:? For old OBD1 setups, the Star Stations use a dynonometer gizmo--a mechanical contraption where the technician "drives" the rear wheels on big steel cylindrical things, and things

Re: Engine light check - Smog Check purgatory
Good to know - I¡¯m not alone, lol. What I¡¯ve learned so far is that the check engine light SHOULD go on at startup. Don¡¯t recall if it¡¯s ever gone on, since before and after the conversion.

Re: Engine light check - Smog Check purgatory
Since you are in Paso Robles, and California Westys is in San Diego, how about a quick call to Ceasar there?? He might tell you where to look.? I just got smogged at a Star Station in the San Diego

Re: Engine light check - Smog Check purgatory
Thanks. It¡¯s definitely not coming on during start up/ignition. I can take the dash off, have done that. What should I be looking for? Wiring issue at the light itself? Bad ignition switch? Ground

I feel for you. My wife didn't bother to change the address for her 98 Yukon when we moved here to Nipomo from the Bay area. Try finding a Star inspection station in south SLO county. Finally found

Re: Engine light check - Smog Check purgatory
Terry All they need to see is the light to come on when you turn the key. If it's not coming on then, maybe it is not hooked up, or something like that. Dennis
