How to Replace a Volvo 850 MAF Sensor in 4 Minutes
Replacing a mass airflow sensor on a Volvo is something anyone can do, mechanic or not. If you've pinpointed your Volvo's problem as the MAF sensor, set aside 2 minutes for removal, and 2 minutes for installation of the new part.

Tools required:
- 7mm Socket
- T25 Torx Bit
Remove the clamp holding the intake pipe to the MAF sensor using a 7mm socket. Pop off the intake pipe. Remove the two T25 screws which fasten the MAF sensor into the airbox, and slide it out. Installation is reverse of removal.
Signs of a bad mass airflow sensor can include:
- Rough idle or inability to idle
- "Limp" mode, or inability for the engine to rev over a certain threshold
- A P0100 through P0104 OBD-II code stored
Get the right part the first time
Always use a new Genuine Volvo or OEM Bosch MAF sensor, as rebuilt or aftermarket units have proven to be highly unreliable for this make of vehicle.
