About two weeks ago, I've had the air filter and MAF sensor replaced to fix a CEL condition -- have been city and highway driving ever since without CEL coming on again. Seems like the problem has been fixed, as expected by many of you on this forum. Thanks!
Yesterday, did an OBDII read using an Actron CP9135 reader and it shows that the Catalyst I/M Moinitor is still "Not Ready", meaning that this particular test has not been completed. All others are fine: Ready or Not Available. Is there a particular MB "drive cycle" I have to put the truck through to get this test completed or does it mean that there is some kind of a fault with the catalytic converter? I still have a few months on the emission control warranty and would like to get this fixed before it expires.
