P0021 Code
2007 CL550 M273 engine I've done camshaft magnets,sensors,and harness extensions.
also checked the timing marks all good.
The code doesn't set off the CEL, but every so often it will get stored in PCM,
anyone have any ideas, oh I forgot the car has 220,000 mi. Runs great, I change the oil every 3,500 mi with Mobile 1 and a good filter
