Check Engine Code
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)
- Disconnected MAP sensor connector or vacuum line
- Failed MAP sensor
- Broken signal wire
- 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.
