What is the p0102 code for the chevy silverado?

P0102 is actually a pretty common code returned in a Chevy Silverado. The code is triggered by the mass air flow (MAF) circuit. If the circuit is low, it can't perform at its required operating range. This really takes a toll on vehicle performance. The most common reasons for the MAF to trigger this code is that the sensor is d***y or has failed. The sensor itself is actually fairly simple to replace. The average cost to repair this part is $230 to $370. Labor makes up about $30 to $40 of that amount. A vacuum or intake manifold leak can trigger it, too. A leak prevents the sensor from getting an accurate reading. Lastly, the MAF sensor wiring could be damaged and will need replacing.
