No CEL - What's wrong with my car ?

I suddenly have no CEL in my car. It went out today for no good reason that I can tell. It's always had that P0420 code sitting in there. Can anyone tell me how to get it back ? I miss my CEL. Not having it makes the cabin dark.

does it light up when you turn the key on? (when its not running) it probably burnt out :laugh:

 

let me behind the wheel for 10 minutes. I can get you cels:biggrin:

 

pull the O2 sensor, give it to me... then you will have a CEL and i wont

Panic averted. It came back. Phew.



It actually came back on the way home on the 19th, but I didn't have the camera in the car again until today. Sorry to have kept everybody on tenterhooks in the mean time

Wow... someone happy to see the CEL...

 

Don't you get tired of people coming on here whining about CELs ? I figured this would make a refreshing change.

 

i feel the same way....something would have to be wrong if i didn't have a CEL

 

Same topic, different car, opposite problem. I Had CEL for months - small Evap system leak. I replaced the rubber gasket on top of the tank - fuel smell inside car is now gone.

Found my OBDII scanner and cleared all seven of the codes, but the light is still on even though "no codes remain."

Am I going to have to bring it in to get scanned to figure out what is wrong?

 

That's an easy fix...



A couple of small strips should cover it up nicely.

Ha ha ha.

 

is the cel suppose to light up at ignition?

 

^Yes^

 

sheeeet. I never saw it lighted up.

 

I get a phantom cel sometimes. Just got it Friday actually. No CEL, but the car won't boost past wastegate. Hook up a code reader, and it says NO DTCS FOUND. Press clear and it says CODE CLEARED SUCCESSFULLY. lol

Its confusing and slightly annoying. It only seems to happen when I have extra people in the car. Too much torque possibly? :biggrin:
