P0106 on a Volvo: Causes, Fixes & Repair Cost
🟠 Moderate severity · drivable
Safe to drive, but rough idle and reduced power, especially under acceleration, are likely until the vacuum leak is fixed.
What P0106 means on a Volvo
On a Volvo, P0106 means the engine computer sees a manifold absolute pressure (MAP) sensor reading that is out of the expected range. The MAP sensor measures intake pressure to help the computer manage fuel and boost on turbo engines. A vacuum or boost leak, or a weak sensor, is the usual cause.
Is P0106 common on Volvos?
P0106 shows up on turbocharged Volvos like the S60, XC60, and XC90, where cracked intake hoses and leaking vacuum lines are common with age. Because these engines run boost, even a small leak changes manifold pressure readings. It is a common and fixable fault on higher-mileage Volvos.
Commonly reported on: S60, V60, XC60, XC90.
Symptoms
- Check engine light is on
- Rough idle
- Reduced power, especially when accelerating
- Poor fuel economy
Common causes
- most common: Vacuum or boost leak in an intake hose
- common: Faulty or failing MAP sensor
- common: Cracked vacuum line to the sensor
- less common: Loose or corroded sensor connector or wiring
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Replace cracked intake or vacuum hoses | Yes | $20–80 |
| Replace the MAP sensor | Yes | $60–180 |
| Pressure-test the intake for leaks | Mechanic | $80–200 |
