Can anyone tell me why ever since I had my truck tuned I get this code p 01 02 airflow signal voltage low? Been like this since it's been tuned never had this problem before not even with my twins and stock tunning ?

The code is set when the intake air temp sensor is reading less than -39°C (-38°F) for more than 2 seconds.

That in conjunction with your maf code could indicate the maf sensor itself is bad because they are both housed in the maf sensor. It could also indicate rubbed wires and things like that. You need to do some trouble shooting. Could be a tune issue as well, but you wont know untill zach double checks the tune.

Have you sent him any data logs? If it happened since the tuning then its obviously a tuning issue and can more than likely be fixed.

Can't get a hold of him so there is no point... this tunning is probably the reason I just sold my twins
