Manifold absolute/barometric pressure circuit low input
The manifold absolute pressure or barometric pressure circuit input is below its calibrated range. Low input means a low circuit signal, not necessarily low pressure in the manifold or a particular altitude. Signal wiring, shared reference voltage and the sensor need vehicle-specific testing.
Can I keep driving?
If the light is steady and the vehicle behaves normally, contact a shop for vehicle-specific urgency advice. If there is severe shaking, stalling, major power loss, a flashing light, smoke or a fuel smell, pull over safely and arrange assistance.
What does this code mean for your car?
The same code can need different checks depending on the model and engine. Enter your vehicle details to find relevant sources and checks.
Symptoms
- Hesitation, reduced power or uneven engine response
- Uneven idle or stalling
- Changed fuel economy or only a check engine light
Possible causes
- 1Pressure signal wire short to ground
- 2Low or missing reference voltage, including trouble in another sensor sharing the supply
- 3Faulty pressure sensor or blocked pressure port
- 4Intake leak or damaged pressure sensing hose, if fitted
These possibilities are not ranked by frequency and do not diagnose your vehicle.
Checks you can safely do yourself
Safe checks only: engine off and cold, car on level ground.
- Save all codes and any freeze-frame data your scanner displays before clearing or repairs.
- With the engine off and cool, visually inspect accessible intake and sensing hoses for splits or separation; do not remove a sensor or hose.
- With the vehicle parked and the engine off and cool, look at accessible wiring and connectors without disconnecting anything; photograph visible damage for the shop.
When you need a shop
Ask the shop to identify whether MAP or BARO is implicated on this vehicle, compare the engine-off pressure reading with ambient conditions and other sensors, and test reference voltage, ground and signal. Intake leak and pressure-port checks should follow the findings.
How much does it cost?
A US repair estimate needs a diagnosis and a local shop quote.
We do not have a verified US repair quote for this fault. Request 2-3 itemized estimates after diagnosis; vehicle, parts and labor determine the cost.

Can I keep driving with P0107?
If the light is steady and the vehicle behaves normally, contact a shop for vehicle-specific urgency advice. If there is severe shaking, stalling, major power loss, a flashing light, smoke or a fuel smell, pull over safely and arrange assistance.
What can cause this code?
Possibilities include pressure signal wire short to ground; low or missing reference voltage, including trouble in another sensor sharing the supply; faulty pressure sensor or blocked pressure port; intake leak or damaged pressure sensing hose, if fitted. The code does not rank causes or identify a part that must be replaced.
Does clearing the code fix the fault?
No. Clearing the code does not repair its cause or prove the fault is absent. It can erase diagnostic data and reset readiness monitors. Even if the code does not reappear immediately, the repair needs verification using the tests appropriate to the vehicle.
What if this code appears during a pre-purchase check?
Arrange an independent professional inspection before buying, including stored data, readiness status and written diagnostic findings. Ask the shop to identify whether MAP or BARO is implicated on this vehicle, compare the engine-off pressure reading with ambient conditions and other sensors, and test reference voltage, ground and signal. Intake leak and pressure-port checks should follow the findings.
How much does repairing P0107 cost?
We do not have a verified US repair quote for this fault. Request 2-3 itemized estimates after diagnosis; vehicle, parts and labor determine the cost.
