MAS Issues

First time poster, like time lurker. I am having a MAS issue on my racecar. I seem to be burning out MAS each event. The error code is P0102-Factory Fault Code 115-Mass Air Flow Sensor Below Limit. When I hook up my Duramteric the voltage does not move with RPM as it should. Can you over volt a MAS and burn it up.

Then today, when troubleshooting that,I got a new error code P1119-Factory Fault Code 5-Heating of Oxygen Sensor ahead of TWC, bank 2. I am guessing the second code is an air leak in the intake?

Any help on the either issue would be appreciated.

Potential causes for P1119:

- Contact resistance.

- Heating resistance too high.

- Open circuit in heating current circuits.

- Open circuit in H02S signal wire.

- Short to B+ (output stage cut off).

I would check the wiring going to your MAF sensor too.

When did this start happening, did it occur after some mod, are you running a standard air intake?
