The hourly rate is the BLS Occupational Employment and Wage Statistics, May 2025 average pay for this trade in the US, $27.13 an hour, times 4 to 5.5 to cover what a shop bills (overhead, tools, insurance, profit). Parts are a band from budget aftermarket to the manufacturer part. Full method.

This is the range for the most common fix, diagnostic scan (check engine light). Which repair your car needs depends on a proper diagnosis.
The manifold absolute pressure sensor reads the pressure in the intake so the computer can work out engine load. The signal it sent is much lower than the engine could ever produce, which usually means a bad sensor, a break in the wiring, a missing ground or a vacuum hose that has come off.
- Safe to drive?
- Short trips only
- Most common cause
- Failed MAP sensor
Drive gently to a shop. The car may idle poorly or stall, and the computer may guess fuel mixture.

Fair Price is not a contractor or a repair shop. Who sees your request
What you may notice
- Rough idle or stalling
- Black smoke or poor fuel economy
- Hesitation
- Check-engine light
Common causes, most likely first
- Failed MAP sensor
- Open or shorted wiring
- Disconnected vacuum hose
- Bad sensor ground
Check this first
Check that the sensor's vacuum hose, if it has one, is attached and not cracked, and look at the sensor plug for loose pins or corrosion. A bad ground can also cause this, so ask the shop to test that.
Other repairs that sometimes fix P0107
| Repair | Typical range, US |
|---|---|
| Vacuum leak repair | $90 to $460 |
| Mass airflow sensor replacement | $120 to $390 |
| CAN bus wiring repair | $170 to $1,125 |
Before you pay
- Ask the shop what test showed this part is the cause, not just that the code appeared.
- Ask for parts and labor listed separately, and for the hours.
- Ask for a written OK before any extra work. Many states require written authorization before repairs.

P0107 questions
MAP or MAF, which is it?
They measure different things. A MAP sensor reads pressure in the intake, and a MAF sensor measures the volume of air entering. Both help work out engine load, and the code number names which one is at fault.
Can I replace it myself?
On many cars it is held by one bolt and a plug, so replacement is simple. Confirm the diagnosis first, since a bad ground or a vacuum hose can set the same code on a good sensor.
Why does it stall?
The computer needs this signal to set fuel, so a wrong value throws the mixture off. At idle, too little or too much fuel makes the engine unstable and it can stall.
How much does it cost to fix P0107?
The most common fix, diagnostic scan (check engine light), has a typical range of $55 to $250 across the US. It is an estimate built from parts prices and local labor wages, not a quote. Your car and shop change it.
