P0107: Manifold absolute pressure sensor input low
Drive carefully. Get it checked within a week or two.
Can I drive with P0107?
Yes, but drive carefully and get it checked soon. The MAP signal voltage is stuck low, simulating constant high engine vacuum.
What does P0107 mean?
P0107 stands for Manifold Absolute Pressure/Barometric Pressure Circuit Low Input.
Symptoms you may notice
- Engine hesitates or jerks when stepping on the gas
- Rough, unsteady idle at stoplights
- Reduced engine power and delayed gear shifts
How much does it cost to fix?
Repair costs for code P0107 depend on the specific underlying root cause, ranging from simple DIY checks to component replacement. The table below lists the most common causes and rough price ranges in USD:
- Short to ground in MAP sensor signal wire
- Faulty MAP sensor internal element
- Broken 5-volt reference power wire
- Corroded connector terminals
What to do next
- Inspect the 3-wire plug on the MAP sensor for green corrosion.
- Measure 5V reference and ground with a digital multimeter.
- Replace the MAP sensor if reference voltages are correct.

About this code
When P0107 triggers, the MAP sensor output is below 0.25 volts. The computer assumes you are coasting down a hill even under hard acceleration, cutting fuel delivery and causing severe hesitation. Check wire harnesses for pinching near brackets before buying a new sensor.
