Mass Air Flow Sensor diagnosis
1999 C280, 95K miles.
I have a check engine light, with error codes P0170 and P0173. I am tempted to replace the MAF sensor but it's terribly expensive. I have an oscilloscope which I can use to probe the leads. Does anyone know what the pins are to probe for the actual MAF values and power voltage?
Thanks.
