P0107

MAP Sensor Circuit Low Input

The ECM has detected that the Manifold Absolute Pressure (MAP) sensor signal voltage is lower than the expected operating range, which the ECM interprets as an implausible low-vacuum or low-pressure reading.

✅ How to Fix — Step by Step

  • Step 1:Inspect MAP sensor vacuum hose
  • Step 2:Check sensor connector
  • Step 3:Test sensor voltage
  • Step 4:Replace MAP sensor
💡 Pro Tip: Check the vacuum hose to the MAP sensor for cracks or splits before replacing the sensor — a leaking hose gives the same low-voltage symptom as a failed sensor.
