P0107 Manifold Absolute Pressure/Barometric Pressure Circuit Low

Fuel and air

P0107 means the manifold pressure (MAP) sensor's signal is too low, usually wiring or a failed sensor.

The engine computer is seeing a MAP sensor signal that's too low to be real, usually from a missing reference voltage, an open signal wire or a failed sensor.

Can I keep driving? Yes, but get it fixed soon.

Usually drivable in a backup mode, but it may hesitate or run poorly. Get it fixed soon.

Common causes

  1. An unplugged or corroded MAP connector
  2. An open or shorted signal or 5-volt reference wire
  3. A failed MAP sensor

Symptoms

  • Hesitation or stumbling
  • Rough running, poor fuel economy
  • Sometimes hard starting

What to check first

  1. Check the connector and wiring.
  2. With the key on, check for about 5 volts on the reference wire and a good ground.
  3. Check the signal voltage against your service information's spec.
  4. Replace the sensor if power and ground are good but the signal stays low.
