124 Emissions Fault Code 11 - What's the fix?
90 300TE 4Matic Wagon. I'm getting a fault code 11 on the self diagnostic module - Tn-signal (rpm signal ) at engine control module faulty. Anyone know the fix for this fault? New MAF, maybe, or is it a signal diminution going into the MAF? Car runs fine, idles fine, starts a little slow in extreme cold, but otherwise no issues. Help me Obi Wan!
