P0106 on a Honda: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

You can usually drive a Honda short-term with P0106, but a wrong MAP reading can cause rough idle and hesitation, so fix it soon.

What P0106 means on a Honda

On a Honda, P0106 means the manifold absolute pressure (MAP) sensor signal is outside the range the engine computer expects. Many Honda engines rely on the MAP sensor to help set fuel delivery, so a bad reading shows up quickly as a range/performance code. It usually points to a vacuum leak, a dirty sensor, or a failing MAP sensor.

Is P0106 common on Hondas?

P0106 is a known code on Hondas, especially as intake gaskets and vacuum lines age and the MAP sensor element gets coated with oil and dirt. Civics, Accords, and CR-Vs with higher mileage see it most. It is a sensor or vacuum fault, not an engine failure.

Commonly reported on: Civic, Accord, CR-V, Pilot.
