Code result
P2074
Manifold Absolute Pressure / Mass Air Flow - Throttle Position Correlation at Higher Load
Moderate severity
What it means
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?
Use caution
The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
