Code P1108 Honda Description
The P1108 Honda code indicates a problem with the Barometric Pressure Sensor Circuit, specifically that the sensor is reading a high voltage. This sensor is responsible for monitoring the atmospheric pressure outside the vehicle, which is crucial for the engine control module to adjust fuel mixture and ignition timing to optimal levels. When the sensor detects a high voltage, it may cause the engine to run too rich or too lean, leading to performance issues such as rough idling, poor acceleration, decreased fuel efficiency, and potential engine misfires.
Common Causes of P1108 Honda
- Faulty Barometric Pressure Sensor
- Damaged wiring or connectors in the sensor circuit
- Corrosion on sensor terminals
- ECM (Engine Control Module) malfunction
- Environmental factors affecting sensor readings (e.g., extreme weather conditions)
Symptoms of P1108 Honda
- Rough idling or stalling
- Decreased fuel efficiency
- Engine misfires
- Check Engine Light illuminated
- Poor acceleration
How to Fix P1108 Honda
- Begin by conducting a visual inspection of the Barometric Pressure Sensor and its wiring to check for any visible damage or corrosion.
- Use a multimeter to test the sensor's voltage output and compare it to the manufacturer's specifications.
- If the sensor is faulty, replace it with a new one and ensure proper installation.
- Check and repair any damaged wiring or connectors in the sensor circuit.
- Clear the trouble codes from the ECM and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P1108 Honda
The cost of repairing a Barometric Pressure Sensor Circuit high voltage issue can vary depending on the specific cause of the problem and the labor rates in your area. On average, the cost of replacing the sensor itself can range from $50 to $200, depending on the vehicle make and model. Labor costs can add an additional $80 to $150 per hour, and the total repair bill may be around $150 to $500. It's recommended to get a detailed estimate from a trusted mechanic before proceeding with the repair.
