thisheregirafFe Posted June 18, 2013 Share Posted June 18, 2013 does anyone know of a safe, easy to to force a CEL? i'm a bit worried that there is a glitch somewhere. couple weeks ago i was having issues which turned out to be the o2 sensor - it never threw a code but the tuner and shop determined the issue. they completely unplugged the sensor and sent me to limp away back to work before returning to replace it later that day. the entire time, even with the o2 completely unplugged, no CEL ever appeared which i though was certainly... off. any easy and quickly reversible way i can force a code to make sure my computer is still registering issues? i can put anything i want down here?!

ras06LGT Posted June 18, 2013 Share Posted June 18, 2013 Does the CEL light up during the initial key-on gauge sweep? You could always unplug the EGT probe (or remove the resistor if you've gone that route). This is assuming you haven't tuned it out of the ECU calibration...

thisheregirafFe Posted June 18, 2013 Author Share Posted June 18, 2013 hmm, good question. haven't noticed that it was or wasn't out during sweep. and i'll check the uppipe, but that code may have very well been taken out... and other ideas if that's the case? i can put anything i want down here?!

thisheregirafFe Posted June 18, 2013 Author Share Posted June 18, 2013 ahhh crap. just checked - it doesn't light up during gauge sweep... is that a fuse or something that's much more of a pain in the arse to get to? i can put anything i want down here?!

jp233 Posted June 19, 2013 Share Posted June 19, 2013 Tons of stuff you can unplug to set a CEL... If the light is out, replace the bulb.... But just pull all code to make sure it is in fact setting a code. Link to comment Share on other sites More sharing options...

But just pull all code to make sure it is in fact setting a code. If you are referring to the bulb on our gauge cluster, our car is using LEDs. So there's almost no way the LED will be dead. I've never heard of such an issue. HOWEVER, when I bought my car some dishonest punks (who rebuilt the car) put some tape over the airbag warning light so they could save a $1000. Found that out three days after buying it Link to comment Share on other sites More sharing options...
thisheregirafFe Posted June 19, 2013 Author Share Posted June 19, 2013 yeah, guess i was in a hurry, or not paying attention, but the light does indeed illuminate at startup. so now i gotta unplug the maf and see if it throws a code. if not, i'm wondering just what the hell is going on that my car won't report any codes :/ i can put anything i want down here?!

jp233 Posted June 19, 2013 Share Posted June 19, 2013 I forgot about the LED wizardry in these cars... but they can die. It's very common on GM 3rd brake lights, especially Caddy's... Link to comment Share on other sites More sharing options...
