My car sat for about a year after it developed a really rough idle and started dying at low speed/rpms. 178k miles on the car. I recently tackled it, replacing the battery (it was dead of course), and the spark plugs. That didn't fix the issue, it still likes to die when i start it and I believe it is in safe mode, as the RPMs won't go above 2k. The dash is showing the SLIP, CHECK ENGINE SOON, and VDC OFF lights. So I took it to the stealership and they pulled the following codes:

P0101 MAF SEN/CIRCUIT
P0103 MAF SEN/CIRCUIT
P0113 MAF IAT SEN/CIRCUIT

They wanted almost a thousand bucks to replace the MAF sensor. I told them nah and took the car home, pulled the MAF sensor and cleaned it. This did not fix the problem. Before I go out and buy a MAF sensor and go down that road, is there anything anyone else can think of that I am missing here? I did not do any of the ecm/electrical resets I have seen, where you stop the pedal five times in five seconds, etc. Should I try this or just go out and get a MAF sensor?

Don't use non OEM parts

The MAF sensor is one of the few sensors that I will buy aftermarket but check online, you can get the OEM Hitachi MAF0031 which is JUST the sensor for about $50. If you cracked the MAF housing then order MAF0029 which has the sensor and the housing.

 

Where are you seeing it for $50? I haven't checked my housing, but when I pulled the MAF and cleaned it, the electrode looking sensor didn't look damaged or even dirty really.

 

When they're toast they look exactly the same, the damage isn't something you will ever see.

There's a $48 one on eBay, use Google to search the part number.

 

Awesome, thank you very much.

 

Do you know who makes the OEM part? I am finding HItachi and Duralast MAF sensors...

 

I was feeling a little mischievous: http://lmgtfy.com/?iie=1&q=Who+manuf...03.5+G35+sedan

Delphi is the correct answer......

 

Huge difference between an actual OEM part and one build to "OEM spec".

Just because it fits doesn't mean it's the same.

 

Final follow up on this one, I bought a replacement MAF, threw it in myself, and did the ECM reset procedure. Fixed the car and cost me about $200. Stealership wanted over $900 to do this work.

 

Awesome., glad everything worked out.
