I changed my MAF and erased the code but it came back, I then scanned my abs and found the C1130 code. I erased everything but in my ecm the p0101 code is in it without the engine light on. I've check the vdc ecm and abs fuses they're all good. I'm stuck I don't know what else to all I've being told is go to the dealer to get my computer reprogrammed. Is this really the issue thanks in advance.

P0101 MAF sensor

C1130 Engine signal 1

If the engine code is still set, the ABS system is disabled, manufactuers do this because the vehicle is not at manufactuer specification,

​ Here is a typical MAF sensor, from the MAF sensor to the throttle body there should be no cuts , holes missing plugs, that will allow false air to get past the MAF sensor. This would set a MAF code. P0101.

Thanks for your insight
So basically you're telling me it's the MAF that causes the c1130 code?

Yes the CK ENG LT , when the light comes on , the ECM uses a substitute value to maintain fuel control , this  protects the catalytic convertor, The ABS system does not distinguish what type of code that is set , it turn the abs OFF, you should not have a faulty component that will affect the drivability of the vehicle . P0101 is always set with these cars, dealer usually replaces the MAF and the upstream 02 sensor.

Hi Reynaldo sorry for the long reply was on vacation.
So the I have 2 upstream sensors on my car the resistance was checked on both and they are good. Does that mean I still have to change them? Thnx
