My 1995 c280 CEL is coming on with the following code:
P0101 -- Mass or volume air flow circuit range/performance problem (Hot film MAF sensor)
Activation requirement CHECK ENGINE lamp:--Two consecutive trips with fault.
Activation of CHECK ENGINE lamp: --At start of next trip
Test to detect fault:--The engine control module checks the air mass signal for its limiting value. A fault recognition is transmitted via CAN to the diagnostic module. The diagnostic module recognizes a failure after approximately 2 seconds.
when I start the car (without stepping on the accelerator ) my engine revs up and down for a few seconds and then levels off. (mostly when hot). The car still drives great (I cleaned the MAS recently), even when the CEL is on.
Is this a staright forward "replace the MAS" situation or could it be the mas wiring? (or will I have to replace the mas to find out) :eek:
