P0106 Code: Manifold Absolute Pressure Sensor Range/Performance

🟠 Moderate severity · drivable

You can usually drive, but the engine may hesitate or idle rough until the problem is found.

What P0106 means

The MAP sensor signal is out of the expected range for the current engine conditions. The computer compares the sensor reading to what it expects and finds a mismatch. This usually points to a vacuum leak or a weak sensor.

Frequently asked questions

Can I drive with P0106?

Yes, but the engine may hesitate or idle rough. A vacuum leak can also let unfiltered air in and lean out the fuel mixture.

What causes a range/performance fault?

The sensor works but reads outside the expected range. Vacuum leaks are the most common reason for this code.

How do I check for a vacuum leak?

Look for cracked or disconnected hoses and listen for hissing at idle. A smoke test at a shop finds leaks fast.
