Cadillac Seville / Cadillac Eldorado Forum Discussion, 2001 SLS - MAF code - runs rough in Past Cadillac Vehicle Discussion; Hi guys, I currently have a p0102 code on my 01 sls I have since replaced the maf itself cleared ...
Yep. The one in the picture is actually a rubber pipe cap - $1.85 at Ace hardware, with clamp - but you need to fill it with a solid plug to keep it from collapsing - I now use a slightly domed PVC pipe cap painted semi-gloss black.
Find a suitable machine screw to replace the rubber Torx bolt at the PCM cover.
IF you have not actually gone into the car's built in code system and manually "clear codes" it will take 3 start-run-drive cycles for the SES to extinguish IF there are no other emissions or powertrain performance faults/codes set.
OK - I see you did clear codes. Something else is fishy.
