P0107

Manifold Absolute Pressure (MAP) Sensor Circuit Low Input

Severity: medium DIY difficulty: 2/5 Typical cost: $20–$250

What P0107 means

The MAP sensor measures intake manifold pressure (vacuum at idle, near atmospheric at WOT). P0107 means its signal is implausibly low — usually a disconnected sensor, broken vacuum line, or failed sensor.

Symptoms

  • Check engine light
  • Rough idle
  • Hesitation under load
  • Stalling

Likely causes (most common first)

  1. Disconnected MAP sensor connector or vacuum line
  2. Failed MAP sensor
  3. Broken signal wire
  4. Cracked vacuum hose to the sensor

Can I keep driving?

Medium — drivable but fix soon

Typical repair cost

DIY fixes can start near $20 (parts only). Shop repairs for P0107 typically run up to $250 depending on the underlying cause and vehicle. Start with the most common cause — Disconnected MAP sensor connector or vacuum line — before throwing parts at it.
