P2197 is a general DTC code that indicates that the signal coming from your Subaru Liberty’s first O2 sensor on the bank two side of the engine is stuck giving off a lean signal. The voltage reading from a normal oxygen sensor should look something like a heartbeat, whereas with P2197 the voltage looks like a … Read more
P2195 is a general OBD2 code that indicates that the signal coming from your Subaru Liberty’s 1’st O2 sensor on Bank 1 Sensor 1 is stuck lean. DTC P2195 is a general code, which means that it has the same meaning for any make, model, or year. It is most typically caused by a bad … Read more
P2272 in the Subaru Liberty is a general diagnostic trouble code. It means that the “bank 2” downstream oxygen sensor (behind the catalytic converter) is continuously sending voltage that indicates a lean air/fuel mixture. This does not necessarily mean that the vehicle is running lean (although it can, but usually doesn’t). P2272 is typically … Read more
P2270 is a general DTC trouble code, which means it has the same meaning for the Subaru Liberty as it would any other vehicle. It means that the oxygen sensor located on bank 1 behind the catalytic converter is continuously sending voltage that indicates a lean air/fuel mixture. This does not necessarily mean that … Read more
Your Subaru Liberty utilizes an evaporative emissions control (EVAP) system to migrate fuel vapors from the gas tank and fuel filler neck, and sends them to the engine to be burned off. When the pressure inside of the fuel tank is too high, P0453, is thrown and the check engine light comes on. If the only … Read more
P0452 is a generic OBD II code that can occur in the Subaru Liberty. It means that your Liberty’s EVAP system has detected low fuel tank pressure. The evaporative emissions control system (EVAP) sends fuel vapors from the fuel tank to the intake manifold to be burned off. When the pressure in the system is … Read more
P2189 is a DTC code that can occur in your Subaru Liberty. It indicates the air fuel mixture is too lean at idle, specifically in bank 2 (we’ll cover how to find bank 2 later). Its is different from the much more common P0174, which indicates that bank 2 is lean at any engine speed. … Read more
P2187 is a DTC code that can occur in the Subaru Liberty. It indicates the air fuel mixture is too lean at idle. The technical definition for P2187 “System Too Lean at Idle: Bank 1”. The code is thrown after your Liberty’s oxygen sensor on Bank 1 (usually sensor 1) has detected that the air … Read more
There are a few reasons why your Subaru Liberty would be overheating when idling. The most common ones include a bad thermostat, water pump, electric fans, and low coolant level. This guide is intended to help you find the cause of this overheating in the most efficient way possible. So, let’s start with what’s easy … Read more
P0068 in the Subaru Liberty is a generic OBD II code. In layman’s terms, it means that the MAP (manifold absolute pressure) and/or MAF (mass airflow sensor) are providing the Liberty’s computer contradicting data compared to what it should be in relation to the throttle position sensor. The throttle position sensor tells the computer how … Read more
