P0068: MAP/MAF - Throttle Position Correlation
What it means
The airflow reading from the MAF/MAP sensor doesn't agree with how far the throttle is open, which often means air is getting in unmeasured.
Severity: Medium Can trigger limp mode or stalling at idle.
Common causes
- Intake leak after the MAF
- Dirty throttle body
- Faulty MAF or MAP sensor
- Throttle position sensor drift
Most common causes first. Exact causes vary by make, model and engine.
Can I fix it myself?
Sometimes DIY. Smoke-test or spray-test the intake for leaks; clean the throttle body.
