MAP circuit low input
What P0107 means
Your car's computer set P0107: MAP circuit low input. It belongs to the fuel and air metering group of codes. It is a generic code, so it means the same thing on every make. The check engine light usually comes on once the fault has been seen on two drives in a row. Until then it shows up as a pending code.
Can I keep driving? Usually safe to drive for now, but get it checked soon. Left alone it can lower fuel economy, fail an emissions test or lead to a bigger repair.
Common causes
- Cracked or disconnected MAP sensor vacuum hose
- Failed MAP sensor
- Wiring or connector problem
Fix the cheapest, most likely cause first. Clearing the code without a repair only turns the light off until the fault comes back.
Check it yourself
Engine off, ignition on, MAP should read close to the outside air pressure (about 100 kPa at sea level).
