P1182 Honda Code - Fuel Temperature Sensor Circuit Low Voltage
Quick Answer
The P1182 Honda code indicates a problem with the fuel temperature sensor circuit, specifically detecting low voltage. Common causes include Faulty Fuel Temperature Sensor: The sensor itself may be defective and not providing accurate temperature readings, Wiring or Connector Issues: Damaged or corroded wiring or connectors in the sensor circuit can cause a poor connection or signal disruption, ECM Malfunction: A malfunctioning ECM may not be able to process the sensor data correctly, leading to the low voltage error. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1182 Honda Description
The P1182 Honda code indicates a problem with the fuel temperature sensor circuit, specifically detecting low voltage. The fuel temperature sensor is responsible for monitoring the temperature of the fuel in the fuel tank. This information is crucial for the engine control module (ECM) to adjust the air-fuel mixture ratio for optimal performance and efficiency. When the sensor reports a low voltage, it means that there is an issue with the sensor or the circuit that connects it to the ECM.
Common Causes of P1182 Honda
- Faulty Fuel Temperature Sensor: The sensor itself may be defective and not providing accurate temperature readings.
- Wiring or Connector Issues: Damaged or corroded wiring or connectors in the sensor circuit can cause a poor connection or signal disruption.
- ECM Malfunction: A malfunctioning ECM may not be able to process the sensor data correctly, leading to the low voltage error.
- Fuel Tank Contamination: Contaminants or debris in the fuel tank can interfere with the sensor's operation and cause incorrect readings.
- Environmental Factors: Extreme temperatures or exposure to harsh conditions can also affect the sensor's performance and trigger this code.
Symptoms of P1182 Honda
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Poor Fuel Efficiency: A malfunctioning fuel temperature sensor can lead to incorrect fuel mixture adjustments, resulting in decreased fuel efficiency.
- Rough Idling: The engine may experience rough idling or hesitation when the fuel temperature sensor is not functioning correctly.
- Engine Stalling: In severe cases, the engine may stall due to incorrect fuel mixture adjustments caused by the faulty sensor.
- Reduced Engine Performance: The vehicle may exhibit reduced engine performance, including sluggish acceleration and overall power.
How to Fix P1182 Honda
- Diagnose the Issue: Use a diagnostic scanner to retrieve the fault code and perform a thorough inspection of the fuel temperature sensor circuit to identify the root cause of the problem.
- Replace the Fuel Temperature Sensor: If the sensor is found to be faulty, it will need to be replaced with a new, OEM-quality sensor.
- Check Wiring and Connectors: Inspect the wiring and connectors in the sensor circuit for any damage or corrosion. Repair or replace any faulty components as needed.
- Reset the ECM: After the repair is completed, reset the ECM to clear the fault code and relearn the sensor's new parameters.
- Test Drive and Monitor: Take the vehicle for a test drive to ensure that the issue has been resolved. Monitor the sensor data and check for any recurrence of the fault code.
Cost to Fix P1182 Honda
The cost of repairing a P1182 Honda code can vary depending on the specific cause of the issue and the labor rates in your area. On average, replacing a fuel temperature sensor can cost between $100 and $200 for the part, with additional labor costs ranging from $100 to $200. Overall, you can expect to pay anywhere from $200 to $400 for the repair at a reputable auto repair shop. It's important to note that these are rough estimates, and actual costs may vary. Be sure to consult with a professional technician for a more accurate assessment based on your vehicle's make and model.
