P0725 is a common OBD2 code that can occur in the Subaru Impreza. It indicates an issue with the engine speed sensor input circuit (which measures the engine speed at the input shaft and helps the PCM determine when and how hard to shift the transmission). It’s a generic code, …

P0523 is a standard OBD2 trouble code that can occur in the Subaru Impreza. In layman’s terms, it indicates the signal from the oil pressure sensor is higher than its normal operating range (in terms of voltage). P0523 is generic (it has the same definition for all vehicles), repair steps …

P0705 is a very common transmission-related trouble code that can occur in the Subaru Impreza. In layman’s terms, it means that your Impreza can’t tell what gear you’ve selected, which can have some real consequences on how it drives. It’s most likely caused by a bad Transmission Range Sensor (TRS), …

Daytime running lights (or DRL) are specialized lights that come on when your Subaru Impreza’s regular headlights are turned off. Their purpose is to make it easier for other drivers to see you, theoretically decreasing the odds of getting into an accident. If your Impreza’s DRL warning light is on, …

P0605 is a relatively rare OBD-II trouble code that can occur in the Subaru Impreza. It indicates that PCM (powertrain control module) is not passing its ROM (read-only memory) self-test when you turn the ignition on. While P0605 is a generic code (it has the same meaning for any car …

P0116 indicates that your Subaru Impreza’s engine coolant temperature sensor is sending a signal to the PCM (powertrain control module) that is outside of its normal operating range (in terms of voltage). While P0116 is a generic OBD2 code (it has the same definition for any car or truck), it …

P0117 is a generic OBD2 code.  It indicates that your Subaru Impreza’s PCM (powertrain control module) has detected the signal coming from the engine coolant temp (ECT) sensor has a voltage level below its normal operating range. With the ECT sensor, as the voltage level drops, it will appear that …

P0036 is a very common O2 sensor-related trouble code. It’s generic, which means it has the same definition for the Subaru Impreza as any other vehicle. This code is almost always caused by a bad heated oxygen sensor or wiring issue and is almost always symptom-free. P0036 should NOT be …

P0058 is a not too common and OBDII trouble code that occurs in the Subaru Impreza. It indicates that the heated oxygen sensor (which we’ll be referring to as HO2S a lot) heater control circuit located at B2S2 is sending a signal to the PCM that is outside of its …

P0056 is a somewhat common O2 sensor-related OBD2 trouble code. It is a generic code, which means it has the same definition for the Subaru Impreza as it would any other vehicle. This code is almost always caused by a bad heated oxygen sensor or wiring issue and almost never …
