what year and I guess a 4.3L?
Vehicle is stock? no BS filters, chips, spacers.
no other codes- any?
Engine is reaching temp @195F?


This code is a rationality check for the mass air flow (MAF), manifold absolute pressure (MAP), and the throttle position (TP) sensors.
Do you have a scanner that sees live data?
If not - check for an air leak after the MAF, be sure the MAP has a good vacuum seal.
