Code P1106 Mercury Description
The P1106 diagnostic trouble code (DTC) for Mercury vehicles indicates an issue with the Manifold Absolute Pressure (MAP) sensor circuit intermittently registering high voltage. The MAP sensor is a crucial component in the engine management system, as it measures the pressure within the intake manifold and provides data to the engine control module (ECM) to calculate the correct air-fuel mixture for optimal combustion. When the ECM detects that the voltage output from the MAP sensor is consistently higher than expected, it triggers the P1106 code.
Common Causes of P1106 Mercury
- Faulty MAP sensor
- Damaged wiring or connectors in the sensor circuit
- Vacuum leak in the intake manifold
- ECM malfunction
- Intake manifold pressure sensor circuit shorted to power
Symptoms of P1106 Mercury
- Decreased fuel efficiency
- Rough idling or stalling
- Hesitation or lack of power during acceleration
- Check Engine Light illuminated
- Vehicle going into limp mode
How to Fix P1106 Mercury
- Begin by conducting a thorough visual inspection of the MAP sensor, wiring, and connectors for any signs of damage. Repair or replace any components as necessary.
- Use a multimeter to test the MAP sensor's voltage output and compare it to the manufacturer's specifications. Replace the sensor if it is out of range.
- Perform a smoke test to check for vacuum leaks in the intake manifold. Repair any leaks found.
- Clear the DTC with a scan tool and test drive the vehicle to ensure the issue has been resolved.
- If the problem persists, consult a professional technician for further diagnosis and repair.
Cost to Fix P1106 Mercury
The typical repair costs for addressing a P1106 code on a Mercury vehicle can range from $100 to $300, depending on the specific cause of the issue and the cost of parts and labor. It's important to note that diagnostic time and labor rates at auto repair shops can vary, with hourly rates typically between $80 and $150. Rates may be higher at dealerships or in metropolitan areas, while independent shops may offer more affordable pricing. For a more accurate estimate, it is recommended to contact local auto repair shops for pricing information.

Frequently Asked Questions about P1106 Mercury Code
1. What does the OBDII code P1106 mean for a Mercury vehicle?
Code P1106 indicates an issue with the Manifold Absolute Pressure (MAP) sensor circuit, specifically an intermittent high voltage signal.
2. What are the common symptoms of the P1106 code in a Mercury?
Symptoms may include rough idling, poor acceleration, reduced fuel efficiency, engine hesitation, and the check engine light turning on.
3. What causes the P1106 code to appear on a Mercury?
Common causes include a faulty MAP sensor, damaged wiring or connectors, a vacuum leak, or issues with the engine control module (ECM).
4. How do I diagnose a P1106 code on my Mercury?
Start by inspecting the MAP sensor and its wiring for damage or loose connections, followed by checking the vacuum lines and testing the sensor output with a multimeter.
5. Can I drive my Mercury with a P1106 code?
Driving with a P1106 code is not recommended, as it can lead to poor performance, increased emissions, and potential damage to the engine over time.
6. How do I fix the P1106 code on a Mercury?
Repairs may include replacing the MAP sensor, repairing damaged wiring or connectors, fixing vacuum leaks, or reprogramming the ECM if necessary.
7. How much does it cost to repair a P1106 code in a Mercury?
The cost varies but typically ranges from $100 to $300 for parts and labor, depending on whether the MAP sensor or other components need replacement.
8. Can a dirty throttle body cause the P1106 code?
While not a direct cause, a dirty throttle body can affect airflow readings and potentially contribute to MAP sensor issues.
9. Does the P1106 code affect fuel economy in a Mercury?
Yes, the P1106 code can result in poor fuel economy due to incorrect air-fuel mixture readings caused by the faulty MAP sensor.
10. How can I prevent the P1106 code from reoccurring on my Mercury?
Regular maintenance, inspecting vacuum lines, and ensuring the MAP sensor and its wiring are in good condition can help prevent this code from returning.
