P2074 Manifold Absolute Pressure / Mass Air Flow - Throttle Position Correlation at Higher Load
At higher load, the relationship between MAP/MAF and throttle position does not match the calibrated map — typically a charge-air leak, restricted intake, or wide-open MAF underread.
Is it safe to drive with P2074?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
