P0113 code High voltoage MAF

How’s it I have p0113 code, I got a new air filter got a new MAF and code still won’t go away any other tips or ideas? I have 2trfe my IAC is built in with the MAF

 

Sounds like either the signal wire (Pin 4 Red/Blue) is broken somewhere between the sensor and PCM or the sensor ground wire (Pin 5 Brown) is broken, has a bad connection at connector IF1, or has a bad ground (although your would likely have other codes as well if that ground was bad).

Get yourself some backprobes and check voltages on pins 4 and 5 of the MAF sensor with it plugged in, Pin 5 (Brown) should be 0v at all times, Pin 4 (Red/Blue) should be somewhere between 0.2v and 4.8v depending on ambient temperature. If voltage checks good at the sensor you will need to find the break in the Red/Blue wire between the sensor and PCM, I saw you had another thread where you said this started after an engine install so checking all the engine wiring for damage would be a good start.

 

Thanks a lot I was curious about the pins and voltage, I’ll double check the wire it looked good to me but I’ll recheck everything

 

Just wanted to let you know and anyone else that might have this problem, even tho I got a brandnew MAF mine was faulty I had go out and buy a new one. Thanks for the help

 

In todays parts market that is not a suprise at all especially with aftermarket parts, we have the same issue at the shop with the constant stream of faulty parts.
