P0107 Code – Manifold Absolute Pressure Circuit Low Input

The P0107 diagnostic trouble code (DTC) indicates that the engine control unit (ECU) has detected a low voltage signal from the Manifold Absolute Pressure (MAP) sensor circuit.

This means the ECU interprets that pressure in the intake manifold is lower than expected, which can lead to incorrect engine load calculations.

The MAP sensor plays a key role in adjusting:

• fuel injection

• ignition timing

• turbo boost (on turbo engines)

Symptoms of Code P0107

Common symptoms include:

• Check Engine light ON

• Loss of engine power

• Poor acceleration

• Engine hesitation

• Hard starting

• Rough idle

• Increased fuel consumption

Common Causes of P0107

Typical causes include:

• Faulty MAP sensor

• Short circuit to ground

• Damaged wiring or connectors

• Vacuum leaks

• Disconnected vacuum hose

• Intake system leaks

• Faulty ECU (rare)

A very common cause is a broken or loose vacuum hose.

How Serious Is Code P0107

The P0107 code is considered a moderate issue, but it can affect drivability.

If ignored, it may lead to:

• incorrect air-fuel mixture

• reduced performance

• increased emissions

How to Diagnose Code P0107

Diagnosis steps:

1. Scan the vehicle with an OBD2 scanner

2. Check MAP sensor live data

3. Inspect vacuum hoses

4. Check wiring and connectors

5. Measure sensor voltage

6. Compare readings with specs

7. Test or replace MAP sensor

How to Fix Code P0107

Possible solutions include:

• replacing the MAP sensor

• repairing wiring issues

• fixing vacuum leaks

• replacing damaged hoses

• cleaning intake system

• resetting ECU after repair

Vehicles Commonly Affected by P0107

This code is found on many vehicles:

• Opel

• Ford

• Volkswagen

• BMW

• Toyota

• Nissan

• Hyundai

FAQ – P0107 Code

Can I drive with code P0107?

Yes, but the engine may lack power and run inefficiently.

Can a vacuum leak cause P0107?

Yes, it is one of the most common causes.

Is this similar to P0102?

Yes, both indicate low signal, but from different sensors (MAP vs MAF).
