What Does Er 55 Mean on a Subaru

Er 55 is a diagnostic trouble code (DTC) found on Subaru vehicles. This code indicates that the vehicle’s evaporative emission control system has detected an issue with the fuel tank pressure sensor. The fuel tank pressure sensor monitors the amount of pressure inside the fuel tank and sends a signal to the computer when it detects any abnormal changes in pressure.

If this signal is not within acceptable parameters, then Er 55 will be stored as a fault code in memory. It can also indicate other issues such as a faulty purge valve or mechanical problems with the EVAP system components. Diagnosis of this DTC should include inspecting all related components for proper operation and functionality before proceeding with any repairs or replacements necessary to resolve this condition.

How Do You Reset the Abs Light on a Subaru?

Resetting the ABS light on a Subaru can be done fairly easily and should take no longer than 10 minutes.

To begin, first make sure you have a code reader or scan tool that is compatible with your car’s OBD-II system.

Next, locate the fuse box in your vehicle – it should be located near the driver’s side of the dashboard.

Once you have identified the fuse box, remove any fuses related to either the anti-lock brakes or traction control systems and then wait for five minutes before replacing them. After waiting, turn on your ignition switch but don’t start up your engine yet; instead use your code reader/scan tool to check if there are any fault codes present in relation to ABS or traction control systems. If there are any fault codes present, clear them using your code reader/scan tool and then restart your engine.

Finally, if all goes well with resetting these codes then simply drive around for at least 15 minutes while monitoring how well (or not) both ABS and traction control work during this test drive period; this process will help determine whether everything was properly reset or not!


Overall, this blog post has provided a comprehensive overview of the Subaru error code ER 55 and what it means for your vehicle. This code is indicative of an issue with the throttle control system, and should be addressed as soon as possible to prevent any further damage from occurring. If you have experienced this issue or are having trouble diagnosing it, it’s best to consult a professional mechanic for assistance.

With proper diagnosis and maintenance, you can ensure that your Subaru runs smoothly for years to come!
