P1106 – Manifold Absolute Pressure Sensor Circuit Intermittent High Voltage
Encountering the P1106 code in your Geely? Here is a complete guide to its causes, symptoms, and solutions.
What Does Code P1106 Mean
The P1106 code indicates that the engine control module (ECM) has detected an intermittent high voltage reading in the Manifold Absolute Pressure (MAP) sensor circuit. The MAP sensor is responsible for measuring the absolute pressure inside the intake manifold, which is used by the ECM to calculate engine load, fuel injection, and ignition timing. When the ECM detects an intermittent high voltage reading, it sets the P1106 code and illuminates the check engine light.
Common Geely Models Affected
- Geely Emgrand EC7
- Geely Emgrand EC8
- Geely GC2
- Geely GC5
- Geely GX7
Symptoms
- Check engine light illumination
- Reduced engine performance
- Decreased fuel efficiency
- Difficulty starting the engine
- Rough idling or stalling
- Loss of power or hesitation during acceleration
- Unstable engine RPM
Causes Table
| Potential Cause | Probability (High/Medium/Low) |
|---|---|
| Faulty Manifold Absolute Pressure (MAP) sensor | High |
| Wiring or connector issues in the MAP sensor circuit | Medium |
| ECM malfunction or software issue | Low |
| Intake manifold leaks or vacuum issues | Medium |
| Failed or corroded MAP sensor connector | Medium |
| Electrical noise or interference in the MAP sensor circuit | Low |
Diagnostic Steps
To diagnose the P1106 code, start by checking the MAP sensor and its circuit for any signs of damage or corrosion. Use a multimeter to measure the voltage reading at the MAP sensor connector, which should change smoothly depending on engine RPM. Check the wiring and connectors for any signs of damage or wear. Use a scan tool to monitor the MAP sensor reading and look for any fluctuations or erratic behavior. If the problem persists, it may be necessary to replace the MAP sensor or repair the wiring and connectors.
How to Fix
The primary repair method for the P1106 code is to replace the faulty MAP sensor or repair the wiring and connectors in the MAP sensor circuit. In some cases, it may be necessary to update the ECM software or replace the ECM entirely. It is recommended to consult a professional mechanic or a Geely dealership for assistance with this repair.
Is it Safe to Drive with this Code
Driving with the P1106 code can cause decreased engine performance, reduced fuel efficiency, and potentially lead to more serious issues such as engine stalling or failure. It is not recommended to drive with this code for an extended period, as it can cause damage to the engine and other components.
Estimated Repair Cost
The estimated repair cost for the P1106 code can range from $200 to $1,000, depending on the underlying cause and the extent of the repairs needed. In some cases, the repair may be covered under warranty, so it is recommended to consult a Geely dealership or a professional mechanic for assistance.
Preventive Maintenance Tips
To prevent the P1106 code from occurring, it is recommended to regularly inspect the MAP sensor and its circuit for any signs of damage or corrosion. Use a multimeter to measure the voltage reading at the MAP sensor connector and check for any fluctuations or erratic behavior. Keep the engine and its components clean and well-maintained, and avoid exposing the engine to extreme temperatures or conditions.
