P0137 is a generic OBDII code. It, therefore, applies to all types of vehicles. Typically, the service engine light is the only symptom of P0137. Other symptoms may also be present, like if the engine is in a bad state of repair. You might also notice that the exhaust smells bad and the service light is on. Besides that, your MPG will also be low. Most of the time, it isn't a risk of a breakdown. Anything that causes the service engine light to appear, on the other hand, should be dealt with as quickly as possible.
