GL450 CEL Code P0420
My 2007 GL450's CEL went on a couple of days ago, I bought a OBDII scanner and read the code is P0420, this should be something concerns about the Three way catalyst converter. But the CEL was gone two days ago and never comes again, but the code still can be detected by OBD scanner. Do I still need to do something? what is the major cause of P0420?
thanks
thanks

Appreciate for your information. I checked by OBDII scanner, the code P0420 still there even the CEL was already gone, So I have to do nothing except the CEL comes again right?

in other words - transient condition. hence my suggestion that due to it disappearing on its own it might have been caused by bad gas.
if it illuminates again- it could be a bunch of things.

correct. the code is stored, but currently not present. when condition is not currently present for x number of ignition cycles the "check engine" light will turn off for that particular code/ condition.
