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.

Most likely causes

  • Vacuum leak — cracked hose, gasket, or PCV

    high

    One of the most commonly reported causes for this code — check this first.

  • MAF sensor contaminated

    medium

    A plausible cause — test and verify before replacing parts.

  • Carbon buildup at throttle plate

    medium

    A plausible cause — test and verify before replacing parts.
