My CEL keeps coming on and I'm getting a P170 code which indicates a bad MAS sensor. I cleaned it and the CEL came on after 1 day. Does anyone have a sensor available as i've been told it may not be the sensor and I don't want to pay for something not necessary.

Thanks

 

How many miles are on your car and do u have k and n filters in

 

My CLK is all stock (no K&N). It just turned 60K. I just changed the 2 air filters and cabin filter about a month before the CEL came on.

 

Probably will need to buy one. I believe you can buy a Bosch one for less than the MB badged one. Check it out.

 

bosch makes the mass air flow for benz so it is the same thing just less i got over 100000 on my clk but i had k and n
i found on on ebay for cheap but my code was running rich
if u want go get a volt meter and test your maf with air going in to it u should read 5v
if u dont it is not workin

 

I just did the MAF in my 2002 CLK55. I was getting code 100 for MAF with the CEL. I bought a new Bosch one from AutohauzAZ for $150 and did myself in about an hour. It took a day for the CEL to go out and the car is fine now.

Good luck--
