P0106: Manifold absolute pressure (MAP) sensor range or performance
The manifold pressure sensor gives readings that do not fit how the engine is running. Usually a vacuum hose, an air leak or the sensor.
| Code | P0106 |

| System | Engine and transmission |
| Group | P01xx, Air and fuel metering |
| Type | Generic: it means the same on every make |
| Can you keep driving? | With care |
What P0106 means
The MAP sensor signal arrives, but it does not fit what the ECU expects from revs, throttle position or other sensors. For example, the pressure does not change when you accelerate, or it does not match atmospheric pressure with the engine off. A vacuum problem or a drifting sensor is most likely.
Most common causes
- Sensor vacuum hose split, loose or with water or oil inside
- Air leaks at the intake manifold or its gasket
- Carbon build-up in the sensor port (common with a dirty EGR valve)
- The MAP sensor itself reading off
- On turbo engines, leaks in the turbo or intercooler hoses
- A corroded connector skewing the reading
Symptoms
- Engine warning light on
- Loss of power or jerking
- Rough idle
- Higher fuel consumption
Can you drive with P0106?
With care You can drive, but the engine may feel flat, use more fuel and foul the catalytic converter. Have it checked soon.

How to check it
In live data, compare manifold pressure with the engine off (it should match barometric) and at idle (it should drop clearly). Also look at the sensor’s small vacuum hose: if it is soft, split or oily, that is the first suspect.
How to read and clear P0106 with Final OBD
Plug an OBD2 scanner in under the steering wheel, switch the ignition on and open Final OBD. Under Faults you’ll see P0106 with its description and whether it’s confirmed, pending or permanent.
If the engine stores it over standard OBD, with FREE you read this code with its explanation for nothing and clear it. With PRO you also read the faults of every control unit and clear them in all of them.
Clearing the code only turns the light off: if the cause is still there, it comes back. Clear it once it’s fixed, and not right before an inspection. It’s all in how to read and clear fault codes and in inspections and OBD.

How do you clear P0106?
With an OBD2 scanner and an app like Final OBD, which clears it for free if it’s stored by the engine control unit. But clearing it only turns the light off: if the cause isn’t fixed, P0106 comes back.
Read it on your car
Final OBD reads and clears engine faults through standard OBD for free, each one explained in plain English. With PRO it also reads the faults of every control unit, each make’s own codes included, and clears them in all of them.
