P010F
Mass or Volume Air Flow Sensor A/B Correlation
Fuel & air metering
Generic OBD-II
High
What it means
P010F means the engine computer sees the two airflow signals it relies on — the mass air flow (MAF) and a second airflow or manifold-pressure reference — disagreeing by more than allowed. Because it can't tell which value is right, it often limits power. The usual culprit is a dirty or faulty MAF/MAP sensor, or an aftermarket intake skewing one reading.
High
Can I keep driving? Often drops into reduced-power or limp mode; drivable but sluggish — get it diagnosed soon.
Common symptoms
What you'll notice
- Check-engine light on

How to diagnose & fix
Work through it in order
- Read freeze-frame data and note which sensor reads out of range.
- Clean the MAF and check the air filter and intake for leaks.
- Inspect the sensor wiring and connectors for damage or corrosion.
- Compare the MAF and MAP readings against each other on a scan tool.
- Replace the faulty sensor; suspect the ECM only after wiring and sensors check out.
FAQ
Quick answers
Is it safe to drive with P010F?+
You can usually limp home, but reduced power and possible stalling make hard driving unsafe. The two airflow readings disagree, so have it diagnosed before relying on the car.
Can I just clear P010F?+
It will reset once, but returns until the sensor mismatch is fixed — often a dirty MAF or an aftermarket intake fooling the readings.
