How are the fuel trims under load and idle?

.

It has the same meaning for the Chevy Traverse as it would any other vehicle. It specifically indicates that your Traverse detected that air-fuel mixture reading as the exhaust gas exits the catalytic converter on the bank 2 side of the engine is too rich. There are three main parts to the defintion of P They are color coded above, and each section is defined seperately. Post catalyst means whatever is happening is after the catalytic converter in terms of exhaust flow. The fuel trim system is what your Chevy Traverse uses to adjust the air-fuel ratio for optimum combustion. So, the number of cylinder heads your Traverse has determines the number of banks it can only be one or two banks. In this case, your Traverse for sure has two banks. Typically, if your Traverse registered P there will be noticeable symptoms. Here are some of the most common ones:.

We recommend Torque Pro. Note that since diesel engines almost always run with excess air, this generally does not apply to diesel engines. Nevertheless, to understand code P and why it sets , it is necessary to understand that the correct functioning of the upstream oxygen sensor is directly related to what happens after the exhaust stream enters the catalytic converter. Thus, to ensure that the catalytic converter is able to clean up the exhaust stream effectively on any given application over the entire planned lifespan of the converter, manufacturers use a second oxygen sensor downstream of the converter, but this is where matters can get complicated. For instance, on many applications, the downstream oxygen sensor has the sole purpose of monitoring the operation of the catalytic converter, which it does by comparing the composition of the exhaust gas leaving the converter with readings obtained by the upstream oxygen sensor.
