Code P1106 Mercury Description

The Manifold Absolute Pressure (MAP) sensor responds to pressure changes in the intake manifold. The pressure changes occur based on the engine load. The MAP sensor has the following circuits:
- 5-volt reference circuit
- Low reference circuit
- MAP sensor signal circuit
The Powertrain Control Module (PCM) supplies 5 volts to the MAP sensor on the 5-volt reference circuit. The PCM also provides a ground on the low reference circuit. The MAP sensor provides a signal to the PCM on the MAP sensor signal circuit which is relative to the pressure changes in the manifold. The PCM should detect a low signal voltage at a low MAP, such as during an idle or a deceleration. The PCM should detect a high signal voltage at a high MAP, such as the ignition is ON, with the engine OFF, or at a wide open throttle (WOT). The MAP sensor is also used in order to determine the barometric pressure (BARO). This occurs when the ignition switch is turned ON, with the engine OFF. The BARO reading may also be updated whenever the engine is operated at WOT. The PCM monitors the MAP sensor signal for voltage outside of the normal range.

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.
