P0107 Code: Manifold Air Pressure (MAP)

Read Time: 3 mins

The P0107 code is a generic OBD-II trouble code and can mean several different things, depending on the car.

P0107 code definition

Manifold Air Pressure (MAP) Barometric Pressure Sensor Circuit Low Voltage Input Problem.

What Does the P0107 Code Mean?

The MAP sensor measures the air pressure inside your engine and relays that information back to the ECM (Electronic Control Module). The ECM uses this data to determine any problems with your engine performance or operation by comparing it against expected values based on other sensors around the vehicle that measure things like temperature and rpm levels. Something wrong with your MAP sensor reading could cause problems like stalling out while driving or hesitation when pressing down on the gas pedal during acceleration.

How to diagnose the P0107 Code?

To diagnose the P0107 code, you must check the MAP sensor voltage. You should also check the MAP sensor resistance. If it is within specification, you can then test the signal with an oscilloscope or voltmeter and see if it matches what’s expected.

If any of these tests reveal problems with your MAP sensor or its wiring harnesses, then replacement may be necessary.

Possible causes of the P0107 Code?

Faulty MAP sensor
Wiring issues
Vacuum leaks
Failed ECM
Clogged or dirty air filter
Failed throttle body

What are the symptoms of the P0107 code?

The engine may run rough.
The check engine light may be on.
The engine idle speed may change, or the vehicle may not start.
If you’re driving and your transmission shifts hard or slips out of gear, this could indicate a problem with your MAP sensor circuit.

How serious is the P0107 code?

The P0107 code is not severe. A mechanic or DIYer can fix it, but it doesn’t need to be fixed immediately. This code is generated when the barometric pressure sensor has a low voltage input problem, which means that your car’s computer thinks there’s something wrong with how information is transmitted from one part of the system to another.
