Few days ago the check engine light came on in my wife's car. I started the car and drove around the block to find it had a whistling sound when the car starts and gets loud as I accelerate the gas. I have a neighbor who has a device to check the error codes he came up with the following:

Error Code 1-10
1. 171-03 Boost Sensor Performance
2. 50-01 MAF Sensor voltage
3. 50-02 MAF Sensor voltage low
4. 50-04 MAF Sensor High/Low
5. 50-10 Sensor range performance
6. 50-07 Sensor performance
7. 50-08 MAF Sensor Performance
8. 17-03 VSS Internment
9. 17-04 VSS Range/performance
10. 17-5 VSS low voltage

With all these codes I first tried cleaning the MAF with the CRC spray and the auto store found my 1 year old battery to be really low, so they replaced it.

The results did not change, even with a new battery and "clean" MAF sensor. Any advice for the next step in trouble shooting? Or with all these error codes does this help pin point to one or more faulty parts?

Thanks a million -Joseph

Those are not OBD2 codes.
You need to find out what the OBD2 codes are. They will start with a P and then 4 numbers.

I'll ask my neighbor to bring his scanner home again and get you those codes. Any ideas off the top of your head what this might mean?

It doesn't mean anything because those aren't the right codes.
How can you have a boost sensor code when you don't even have a turbo?

WrenchTech,

We ran the check engine test again and the readings came back with the following 2 codes:

P0102 - Generic Mass or Volume Air Flow circuit CURRENT
P0102 - Generic Mass or Volume Air Flow circuit PENDING

I also noted the ECU codes:

ECU1 ($C6D78888)
ECU2 ($C6D78888)
NO FAULT CODES

What do you suspect the issue could be?

Thanks!

That indicates an issue with the Mass Air Flow system. First check for any air leaks in the snorkel or related hoses and the wiring to the sensor before considering a new sensor.

Another thing that can set that code is a restricted exhaust system. A pressure test before the Converter would answer that.
