P0107
ModerateManifold Absolute Pressure (MAP) Sensor Circuit Low
P0107 is usually drivable short-term, but rough running or stalling can be inconvenient and the engine may run rich or lean. It's low-risk mechanically. Check the connector and wiring before replacing the sensor — a cheap fix often hides there.
What this code means
The manifold absolute pressure (MAP) sensor measures intake-manifold pressure, which tells the computer how hard the engine is working so it can set the right fuel and timing. P0107 means the MAP signal is reading too low (or shorted to ground). The usual causes are a failed sensor or a wiring/connector fault. Because the computer relies on this for fueling, a bad MAP reading can cause rough running, poor power, and bad fuel economy.
Symptoms you might notice
- Rough idle or stalling
- Hesitation or poor acceleration
- Reduced fuel economy
- Black smoke or a rich/lean running condition
- Check-engine light
What it costs to fix
Typical range: $50–$300 · about ~0.3–1 hrs of labor
| If the cause is… | Part | Labor |
|---|---|---|
| MAP sensor | $30–$120 | ~0.3–0.8 hrs |
| Wiring / connector repair | $10–$120 | ~0.5–1.5 hrs |
The MAP sensor is inexpensive and usually easy to reach, so this is typically a low-cost repair. A wiring short takes a bit longer to find but the parts are cheap.

Frequently asked
Can I drive with P0107?
Usually yes, short-term, though expect rough running or hesitation. It isn't typically a safety issue, so you can drive to get it diagnosed; fix it before an emissions test.
What does the MAP sensor do?
It measures how much pressure (or vacuum) is in the intake manifold, which reflects engine load. The computer uses that to decide how much fuel to add and when to fire the spark, so a wrong reading throws off running.
Is P0107 the sensor or the wiring?
Either — a failed sensor is common, but a wire shorted to ground or a corroded connector reads the same way. Checking the wiring first can save replacing a sensor that was fine.
How much does it cost to fix P0107?
Usually inexpensive — the MAP sensor is cheap and easy to reach, and wiring repairs are modest. Confirm the wiring before buying the sensor.
