P006A
MAP - Mass or Volume Air Flow Correlation Bank 1
Fuel & air metering
Generic OBD-II
High
What it means
P006A means the engine computer sees a mismatch between what the mass air-flow (MAF) sensor reports and what the manifold pressure (MAP) sensor implies for the same conditions on bank 1. The two airflow signals don't agree, so the ECM can't trust its air measurement — often causing rough running, poor economy, or limp mode.
High
Can I keep driving? Often drivable but the car may run rough, hesitate, or enter limp mode; a badly wrong airflow reading can make it hard to start or stall.
Common symptoms
What you'll notice
- Check-engine light on
- Rough running, hesitation, or reduced power
- Car may drop into limp mode
- Hard starting or occasional stalling in worse cases
- Reduced fuel economy
Common causes
Most likely first

- Faulty MAF or MAP sensorCommon
- Intake air leak or aftermarket intake affecting airflow readingsCommon
- Restricted air filter or clogged intake ductingLess often
- Faulty engine control module — rareLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and compare live MAF and MAP readings against expected values.
- Replace a dirty air filter and clean the MAF sensor element with MAF-specific cleaner.
- Inspect the intake ducting for leaks, loose clamps, or a poorly fitting aftermarket intake.
- Test the MAF and MAP sensors individually and replace whichever reads implausibly.
- If sensors and intake are good, consider the ECM last. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P006A?+
Short trips are usually fine, but the engine may run poorly or enter limp mode. Fix it soon to avoid hard starting or stalling.
Can I just clear P006A?+
You can, but it returns until the airflow-reading mismatch is corrected — often as simple as a clean MAF sensor or a sealed intake.
