Getting code P0103

I am getting a code reading of P0103, MAF Sensor High Circuit.


I cleaned the MAF... no change
I bought new MAF... no change
No air leaks in the cold air intake before or after the MAF
The wires to the MAF seem fine (harness is brand new)


Before I take the car back to the place that sold me the harness / dyno, is there anything else I can check on my own... I am still new to the LS world.


Thanks

Re: Getting code P0103

After taking it back to the place where I got it tuned and dyno, I learned that tuning it in Speed Density will cause the MAF DTC code. I got re-tuned and light turned off permanently for the DTC but if it is hooked up to the sensor it will still get a P0103 DTC. This all has to do with the large cam.


Tuning a vehicle is truly high tech. Wish I knew more about that process. Very interesting to say the least.

Re: Getting code P0103

If you tune SD you don't need the MAF. Unless running massive boost I would not use an SD tune.

That said your tuner should me able to disable the MAF so you do not get error codes.

You can also mod parameters to not trigger CLE for the P0103 error. It will still show as a current and historical error but will not trigger
