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 |

| Type | Generic: it means the same on every make |

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 this same explanation and whether it’s confirmed, pending or permanent.
With Free you read this code with its short description for nothing, and clear it if the engine stores it over standard OBD. With Pro you get the full explanation, how the car was running when it was logged (revs, temperature, load) and clearing in every control unit.
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 the ITV. It’s all in how to read and clear fault codes and in the ITV and OBD.

P0106 is a generic code, so it means the same on any make, for example on Audi, BMW, Fiat, Mazda, Peugeot, Volkswagen. See what Final OBD does on your car in makes and models.

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 the faults of every control unit for free, including each make’s own codes, and with Pro explains each one in plain English. Free clears engine faults at no cost.
