P1106 – Manifold Absolute Pressure Sensor Circuit Intermittent High Voltage
Let’s break down exactly what the P1106 trouble code means for your Geely and how to fix it.
What Does Code P1106 Mean
The P1106 trouble code indicates a problem with the manifold absolute pressure sensor circuit, specifically an intermittent high voltage condition. This code is often associated with issues in the sensor or its wiring, which can affect the engine’s performance and fuel efficiency. When diagnosing the P1106 code, it is essential to understand that the manifold absolute pressure sensor plays a critical role in monitoring the engine’s intake manifold pressure, which is used to calculate fuel injection and ignition timing. The Geely P1106 error can cause a range of problems, from decreased fuel efficiency to engine stalling.

Diagnostic Steps
When diagnosing the P1106 code, start by inspecting the manifold absolute pressure sensor and its wiring for any signs of damage or corrosion. Use a multimeter to verify the voltage and resistance readings of the sensor circuit, comparing them to the factory specifications in the workshop manual for your specific engine size. Monitor the sensor’s output voltage as the engine is running, which should change smoothly depending on engine RPM. Check for any trouble codes or freeze frame data in the ECU to help identify the cause of the problem. Fixing the P1106 code requires a thorough understanding of the engine’s electrical system and the sensor’s operation.
How to Fix
The primary repair method for the P1106 trouble code involves repairing or replacing the faulty component, which may be the manifold absolute pressure sensor, its wiring, or other electrical components in the circuit. In some cases, cleaning or replacing the sensor connector may resolve the issue. When fixing the P1106 code, it is essential to follow proper troubleshooting procedures and consult the workshop manual for specific instructions and guidelines.
Is It Safe to Drive with This Code
Driving with the P1106 code active can pose technical risks and consequences for the vehicle, including decreased fuel efficiency, engine stalling, and potential damage to other engine components. While it may be possible to drive the vehicle for a short period, it is not recommended to continue driving with this code, as it can lead to more severe problems and costly repairs.
Estimated Repair Cost
The estimated repair cost for the P1106 trouble code can range from $200 to $1,000, depending on the specific cause of the problem and the components that need to be replaced. In some cases, the repair may be covered under warranty, while in other cases, it may require out-of-pocket expenses.
Preventive Maintenance Tips
To properly maintain the automotive system and prevent the P1106 code from occurring, it is essential to follow regular maintenance schedules, including oil changes, spark plug replacements, and inspections of the engine’s electrical system. Keeping the engine clean and free of debris, as well as avoiding extreme temperatures and driving conditions, can also help prevent issues with the manifold absolute pressure sensor and its circuit.
When working with the P1106 code, it is crucial to use proper diagnostic equipment and follow established troubleshooting procedures to avoid misdiagnosis and unnecessary repairs. In some cases, the problem may be related to a faulty ECU or other engine components, requiring specialized knowledge and experience to repair. As a mechanic, it is essential to stay up-to-date with the latest technical information and training to ensure accurate and efficient repairs.
