Code P1104 MINI Description
The P1104 MINI code refers to the Differential Pressure Sensor Intake Manifold Plausibility. This code indicates that there is an issue with the differential pressure sensor in the intake manifold. The differential pressure sensor is responsible for measuring the difference between the pressure inside the intake manifold and the atmospheric pressure. This information is crucial for the engine control unit (ECU) to adjust the air-fuel mixture for optimal combustion.
Common Causes of P1104 MINI
- Faulty differential pressure sensor
- Wiring issues
- Vacuum leaks in the intake manifold
- Intake manifold issues
- ECU malfunction
Symptoms of P1104 MINI
- Poor fuel efficiency
- Rough idling
- Hesitation during acceleration
- Engine misfires
- Illuminated check engine light
How to Fix P1104 MINI
- Diagnose the issue by using a diagnostic scanner to confirm the P1104 code and inspect the differential pressure sensor and related components.
- Check the wiring harness for any signs of damage or corrosion and repair or replace as necessary.
- Inspect the intake manifold for vacuum leaks and repair any leaks found.
- Test the differential pressure sensor to ensure it is functioning properly or replace it if faulty.
- Clear the error code from the ECU and perform a test drive to confirm that the issue has been resolved.
Cost to Fix P1104 MINI
The typical repair costs for addressing the P1104 MINI code can vary depending on the specific cause of the issue. In general, the cost of replacing a faulty differential pressure sensor and addressing related wiring or vacuum leak issues can range from $200 to $500, including parts and labor. However, it's important to note that the actual cost can be higher or lower based on the location, vehicle make and model, and labor rates at the auto repair shop. It is recommended to obtain a specific cost estimate from a qualified mechanic before proceeding with the repair.
