System Too Rich (Bank 2)
The engine is getting too much fuel or not enough air on bank 2. The computer cannot correct the mixture back to normal, so it set this code.
You may be able to drive short distances, but fuel economy, performance, and emissions can be affected. A very rich condition can damage the catalytic converter if ignored for too long.
P0175 means the engine control module has detected a rich air-fuel condition on bank 2. Fuel trim values have moved negative enough that the PCM is trying to reduce fuel, but the mixture remains too rich. This is usually caused by excess fuel delivery, restricted air intake, incorrect sensor data, or a control fault affecting bank 2.
Bank 2 is the side of the engine that does not contain cylinder 1 on engines with two cylinder banks.
Yes, but it is less common than a fuel pressure problem, injector leak, or air measurement issue. The sensor should be tested before replacing it.
It may turn off temporarily if the condition goes away, but it usually comes back until the real cause is fixed.
Short drives may be possible, but do not ignore it. A rich running condition can waste fuel and damage the catalytic converter.
