I cleaned the mass air flow sensor. Cleaned throttle body, new air filter. Wire red white and green, yellow 4.92 volts at plug. Still light returns. Help, where to check or how to move forward?

This code is for the IAT which is part of the MAF, but we are going to have to run through this testing to find out where the issue is.

So here are a couple guides that will help with this testing:

Below is the testing that you need to run through. Please review this material because it will help explain what the issue is and then we can proceed with the testing and go from there.

Let me know what questions you have.

Thanks
