P0107: Manifold absolute pressure (MAP) sensor circuit low
The ECU sees a voltage that is too low from the manifold pressure sensor. Usually the connector, a broken or earthed wire, or the sensor.

What P0107 means
The MAP sensor sends a voltage that rises with manifold pressure. If the ECU sees it below what is possible, it stores this code. It is almost always electrical: the 5 volt supply is missing, the signal wire is broken or touching earth, or the sensor has failed.
Most common causes
- MAP sensor connector unplugged, loose or corroded
- Signal or supply wire broken
- Chafed wire touching earth
- A faulty MAP sensor
- A short in another sensor sharing the same 5 volt supply
Symptoms
- Engine warning light on
- Loss of power, sometimes with limp mode
- Unstable idle or hard starting
- Higher fuel consumption
Can you drive with P0107?
With care You can drive, but the engine is running on backup values and performs less well. Get it fixed soon.

How to check it
With the ignition on and the engine off, check manifold pressure in live data: if it shows a very low value or zero instead of atmospheric pressure, the fault is electrical. Check first that the connector is fully seated.
How to read and clear P0107 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 P0107 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 P0107?
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, P0107 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.
