MAF wiring schematic

Taken from the 2014 Service Manual
For those that might need it

Yeah, but that does not tell you what each circuit in the MAF is.

L99/LS3:
Pin - Wire - Circuit- Function
A - 0.5 - YE - 492 -MAF Sensor Signal
B - 0.5 - BK/WH - 451- Ground
C - 0.5 - PK - 239- Ignition Voltage
D - 0.5 - TN - 2760 - Low Reference
E - 0.5 - L-BU - 6289 - Intake Air Temperature Sensor Signal

LLT ENGINE:
Pin Wire Circuit Function
1 0.5 TN 2760 Low Reference
2 0.5 BK/WH 451 Ground
3 0.5 L-BU 6289 Intake Air Temperature Sensor Signal
4 0.5 PK 239 Ignition Voltage
5 0.5 YE 492 MAF Sensor Signal

Thanks for the addition, I had a request for the page so this was a way to post it for him.

I don't have a schematic for the LLT since it's older and my manual only shows the LFX. Feel free to post a schematic for yout LLT specs, Thanks

[FasNuf]

Oh and just so there's no confusion...

All of engine performance diagrams 1-6, MAF is on Page 5.

There has to be some sort of typo because there is no Circuit 239 for Ignition Voltage, only 439 which is pin 19 on the PCM.

And yes I resurrected a 3 year old thread because I'm having issues with my car and trying to confirm I'm not crazy and 439 is indeed correct.

So which motor are you working on?
