Code P0137 2004 Toyota Prius Description
The P0137 code in a 2004 Toyota Prius refers to an issue with the Oxygen Sensor Circuit on Bank 1 Sensor 2. This sensor is responsible for monitoring the oxygen levels in the exhaust gases and sending this information to the engine control module. The engine control module then uses this data to adjust the air-fuel mixture for optimal combustion. When the oxygen sensor circuit detects a low voltage signal, it means that there is a problem with the sensor's ability to accurately measure oxygen levels in the exhaust gases.
Common Causes of P0137 2004 Toyota Prius
- Faulty oxygen sensor
- Damaged wiring or connectors in the sensor circuit
- Engine control module malfunction
- Exhaust leaks near the sensor
- Contaminated sensor due to oil or coolant leaks
