P0102 on a Volvo: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

Usually drivable, but a weak MAF signal can cause rough idling or stalling, so get it checked soon.

What P0102 means on a Volvo

On a Volvo, P0102 means the mass air flow (MAF) sensor is sending a signal lower than the engine computer expects. The computer can't meter the incoming air, so fuel delivery goes off and the engine may idle rough, hesitate, or stall.

Is P0102 common on Volvos?

P0102 shows up on Volvos with higher mileage, especially the older 2.4L and 2.5T five-cylinder engines in the S60, V70, and first-generation XC90. MAF sensor failures are well known on these engines, and a cracked intake hose between the air box and the engine can also cause a low reading.

Commonly reported on: S60, V70, XC90, XC60.

Symptoms

Check engine light is on
Rough idle or stalling
Hesitation or lack of power
Poor fuel economy

Common causes

most common: Faulty MAF sensor
common: Dirty or contaminated MAF sensor wire
common: Cracked intake hose or loose clamp letting air bypass the sensor
less common: Damaged wiring or connector at the MAF sensor

How to fix it
