P219A is a generic OBDII code. The code indicates that the air/fuel ratio is out of balance (too rich or too lean). Your vehicle is equipped with oxygen sensors that measure the air-fuel ratio of your engine. It’s these sensors that are reporting the problem with the air-fuel ratio. There are two scenarios. The … Read more
U0100 is a generic network communication code, meaning it has the same definition for any vehicle made in the 1996 model year or newer. This code tells you that communication has been lost between the ECM/PCM (main computer) and a particular control module has been completely lost. When a vehicle has U0100, most of the … Read more
P1153 is not a very common diagnostic trouble code. It can have different meanings depending on the manufacturer in question. However, for the purposes of this article, it means: P1153:HO2S Insufficient Switching (Bank 2, Sensor 1) This is the most common meaning of this code and applies to vehicles made by: Honda (Acura, Honda) General … Read more
P1133 can have different definitions depending on the vehicle manufacturer in question. However, for the purposes of this article, it means: HO2S Insufficient Switching (Bank 1, Sensor 1) This is far and away the most common meaning of this code and applies to vehicles made by: Honda (Acura, Honda) General Motors (Cadillac, Buick, Chevrolet, GMC, … Read more
U0073 Definition: Control Module Communication Bus”A” Off U0073 is a fairly common trouble code. It is generic, so it has the same meaning for your vehicle as it would any other. This code appears when something has interrupted the communication between two of your vehicle’s control modules. The most common causes of U0073 are wiring … Read more
P2276 is a general diagnostic trouble code. It means that the third “bank 2” downstream oxygen sensor (behind the catalytic converter) is continuously sending voltage that indicates a lean air/fuel mixture. Having this code does not necessarily mean that the vehicle is running lean (although it can, but usually doesn’t). P2276 is typically caused … Read more
P2274 is a general DTC trouble code. It means that the third oxygen sensor located on bank 1 is continuously sending a voltage signal that indicates there is a lean air/fuel mixture. This does not necessarily mean that the vehicle is running lean (although it can). It’s usually caused by a bad oxygen sensor, … Read more
P2018 is a generic diagnostic trouble code (DTC) that indicates an issue with the intake manifold runner position sensor/valve (we will be referring to the sensor by its common abbreviation of IMRC). P2018 Definition: IMRC – Switch Circuit Intermittent (Bank 1) IMRC The IMRC’s job is to help the vehicle’s powertrain control module (PCM) allow air … Read more
P2198 Definition: Oxygen Sensor – Stuck Rich (Bank 2, Sensor 1) P2198 is a generic diagnostic trouble code that indicates the B2S1 O2 sensor is stuck rich. It does not necessarily mean that the vehicle itself is running rich (although it very well could). Oxygen Sensor When you get P2198, the voltage level being recorded … Read more
P2138 is a generic powertrain code that can affect any make or model of vehicle that has a “drive by wire” throttle system (almost every vehicle made today). It means that your vehicle’s “D” and “E” throttle position sensors do not agree with one another on how much gas you are giving the vehicle. They … Read more
