How to Fix the P0183 Code in Your Subaru Outback
If you're a Subaru Outback owner and your vehicle's diagnostic system has flagged an error code P0183, you're probably wondering what it means and how to fix it. The P0183 code indicates a problem with the fuel temperature sensor, specifically that the sensor's signal is higher than expected. This can affect the performance of your vehicle, potentially leading to issues with fuel efficiency and engine performance.
Understanding the P0183 Code
The P0183 error code is associated with the fuel temperature sensor 'A' circuit high input. This sensor measures the temperature of the fuel in your vehicle and sends this data to the engine control module (ECM). When the ECM receives a signal from the fuel temperature sensor that is abnormally high, it triggers the P0183 code.
Common Symptoms
- Check engine light is on
- Decreased fuel efficiency
- Possible difficulty in starting the engine
