164.122--642.940 CDI B2/7 Hot film mass airflow (value above limits)
New HFMAF installed, new EGR installed, Code cleared 10 times!
Wiring rings out to N3/9 ECM .2 .3 ohms on all leads
Both B2/6 and B2/7 read normal running and read normal engine stopped, but N3/9 throws HFMAF sensor (value above limit) immediately after start, but shows normal when read! Raw value is suppose to be between 200-450 us and it returns 487 us
Also, after readapting both MAF and EGR while running, no new code until restart and then, instantly shows 1 event.
642 150 61 79 ECU is installed.
642 090 82 37 MAF is installed
The ECM computer was superseded 4 times in 18 months by MB up to 2/2008.
642 150 61 79 Earliest, just like mine
642 150 23 77
