P0107 Mercury Code - Manifold Absolute Pressure/Barometric Pressure Sensor Low Input

Quick Answer

The Manifold Absolute Pressure (MAP) Sensor is located on the intake manifold and measures the intake manifold pressure. Common causes include Faulty Manifold Absolute Pressure (MAP) Sensor, Manifold Absolute Pressure Sensor harness is open or shorted, Manifold Absolute Pressure Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0107 Mercury Description

The Manifold Absolute Pressure (MAP) Sensor is located on the intake manifold and measures the intake manifold pressure. The Powertrain Control Module (PCM) uses this information to determine the air charge and to provide the input for various engine control functions. Under normal operation, the greatest pressure that can exist in the intake manifold is at ignition ON, and engine OFF, which is equal to the Barometric Pressure (BARO). The lowest manifold pressure occurs when the vehicle is idling or decelerating. The ECM monitors the MAP sensor signal for pressure outside of the normal range. The sensor translates this action into electrical resistance. The MAP sensor may be integrated with an Intake Air Temperature (IAT) sensor. The Diagnostic Trouble Code (DTC) will be set when the MAP Sensor operating voltage is below the minimum calibrated parameter of 0.024 volt.

Frequently Asked Questions about P0107 Mercury Code

1. What are the common symptoms of OBDII code P0107 in a Mercury vehicle?

- Common symptoms include rough idling, poor acceleration, decreased fuel efficiency, and potential stalling of the engine.

2. What can cause the Manifold Absolute Pressure/Barometric Pressure Sensor Low Input code P0107 in a Mercury?

- Possible causes include a faulty MAP/BP sensor, wiring issues, vacuum leaks, clogged air filters, or problems with the engine's intake system.

3. How can I diagnose the cause of OBDII code P0107 in my Mercury?

- Use a diagnostic scanner to read the code, check the MAP/BP sensor's voltage output, inspect the sensor and its wiring for damage, and perform a smoke test to detect any vacuum leaks.

4. Can I drive my Mercury with the P0107 trouble code?

- It's not recommended to drive your vehicle with the P0107 code present, as it can lead to poor engine performance and potential damage if left unresolved.

5. How can I repair the Manifold Absolute Pressure/Barometric Pressure Sensor Low Input code in my Mercury?

- Repair options may include replacing the MAP/BP sensor, repairing damaged wiring, fixing vacuum leaks, cleaning the air filter, or addressing any intake system issues.

6. Will resetting the OBDII code P0107 in my Mercury make it go away permanently?

- Resetting the code will clear it temporarily, but if the underlying issue causing the P0107 code is not fixed, it is likely to reappear after driving the vehicle again.

7. Can a DIY enthusiast fix the P0107 code in a Mercury, or should I seek professional help?

- Depending on your skill level and access to tools, you may be able to address the P0107 code yourself by following repair guides and diagnostic steps. However, if you're unsure, it's best to consult a professional mechanic.

8. How much does it cost to repair the Manifold Absolute Pressure/Barometric Pressure Sensor Low Input code in a Mercury?

- The cost of repair can vary depending on the specific cause of the issue, but it may range from around $100 to $300 for parts and labor.

9. Will the P0107 code cause my Mercury to fail an emissions test?

- Yes, the P0107 code can potentially cause your Mercury to fail an emissions test due to improper engine performance and increased emissions output.

10. Is it safe to continue driving my Mercury if the P0107 code is present but the vehicle seems to be running fine?

- While the vehicle may seem to run fine initially with the P0107 code, it's still recommended to address the issue promptly to prevent any further damage or potential safety hazards.
