Error code P0107 indicates that your vehicle's Manifold Absolute Pressure (MAP) sensor is sending a signal that's lower than expected to the engine control module. This sensor measures intake manifold pressure to help calculate fuel injection and ignition timing. When it malfunctions, you'll likely experience poor engine performance, rough idling, and decreased fuel economy.

How to Fix Error Code P0107

  1. Turn off engine and ensure safety

    Never work on a hot engine or with the engine running when checking electrical components
  2. Locate the MAP sensor

  3. Inspect vacuum lines and connections

  4. Test MAP sensor electrical connections

    Ensure multimeter leads don't touch each other or other metal components while testing
  5. Test MAP sensor with vacuum pump

  6. Check engine control module wiring

  7. Replace MAP sensor if faulty

    Do not overtighten mounting screws as this can crack the sensor housing

When to Call a Professional

Contact a qualified mechanic if you're uncomfortable working with electrical components, if wiring damage extends to the engine control module, or if the problem persists after replacing the MAP sensor. Professional diagnosis may be needed if multiple sensors are showing faults simultaneously.

Frequently Asked Questions

What causes OBD-II error code P0107?
P0107 is typically caused by a faulty MAP sensor, damaged vacuum hoses, corroded electrical connections, or wiring issues between the sensor and engine control module. Less commonly, it can result from a clogged air filter or intake manifold problems.
Can I drive with error code P0107?
While your vehicle may still run with P0107, it's not recommended for extended driving. You'll experience poor fuel economy, rough idling, lack of power, and potential engine damage from incorrect air-fuel mixture. Address the issue promptly to avoid further problems.
How much does it cost to fix P0107?
DIY repair costs range from $30-80 for a new MAP sensor plus vacuum hoses if needed. Professional repair typically costs $150-300 including labor. Costs vary based on vehicle make, model, and local labor rates.
What are the symptoms of a bad MAP sensor?
Common symptoms include rough idling, poor acceleration, increased fuel consumption, black exhaust smoke, engine hesitation, and check engine light. Some vehicles may also experience hard starting or stalling.
How long does a MAP sensor last?
MAP sensors typically last 80,000-120,000 miles under normal conditions. However, contamination from oil vapors, extreme temperatures, or electrical issues can cause premature failure. Regular maintenance helps extend sensor life.
