Code result
P2073
Manifold Absolute Pressure / Mass Air Flow - Throttle Position Correlation at Idle
Moderate severity
What it means
At idle, the relationship between MAP/MAF and throttle position does not match the calibrated map — typically a vacuum leak, dirty MAF, sticking throttle plate, or sensor drift.
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.
