P2195 is a general OBD2 code that indicates that the signal coming from your Scion tC’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 Scion tC 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 Scion tC 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 Scion tC 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 Scion tC. It means that your tC’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 Scion tC. 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 Scion tC. 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 tC’s oxygen sensor on Bank 1 (usually sensor 1) has detected that the air … Read more
There are a few reasons why your Scion tC 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 Scion tC 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 tC’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
A smoking engine is a serious thing. If your Scion tC’s engine has smoke coming from it, it needs to be addressed right away. It can be caused by quite a few different problems, none of which should be ignored. The most common reasons why your tC’s engine would smoke include overheating, burning oil, or … Read more
