P0102 on a Honda: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

You can usually drive a Honda with P0102, but the engine may run rough or use more fuel until the sensor is fixed.

What P0102 means on a Honda

On a Honda, P0102 means the mass air flow sensor signal is too low. The MAF sensor measures incoming air so the engine computer can add the right amount of fuel. A weak signal on a Honda usually comes from a dirty sensor, a failing sensor, or an air intake problem.

Is P0102 common on Hondas?

P0102 shows up on Hondas with higher mileage, especially Accords, Civics, and CR-Vs. Honda MAF sensors get coated with dust and oil over time, especially with a dirty air filter. The sensor signal drops as it gets contaminated, and cleaning often restores it.

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