P0107 Code: Manifold Absolute Pressure Sensor Circuit Low
🟠 Moderate severity · drivable
Short trips are usually okay, but the engine may stall or run poorly while the code is active.
What P0107 means
The MAP sensor voltage is too low, which means the computer sees a very low pressure signal. This can be caused by the sensor itself, the wiring, or a short to ground. The engine may run rich or stall.
Symptoms
- Check engine light on
- Engine stalls or runs rich
- Rough idle
- Poor fuel economy
- Lack of power
Common causes
- most common: Faulty MAP sensor
- common: Open or shorted wiring in the MAP circuit
- common: Broken or blocked vacuum hose
- less common: Corroded connector terminals
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Replace the MAP sensor | Yes | $40–120 |
| Repair the MAP sensor wiring | Yes | $20–80 |
| Replace the vacuum hose | Yes | $5–20 |
| Clean the connector | Yes | $0–20 |
Frequently asked questions
Can I drive with P0107?
Short trips are okay, but the engine may stall or run poorly. Low MAP readings make the computer add fuel and run rich.
What does a low MAP signal mean?
The sensor is sending a very low voltage, which the computer reads as very low intake pressure.
Should I replace the MAP sensor first?
It is a common fix, but check the wiring and vacuum hose first so you do not replace a good part.
