Code P0038 2006 Toyota Prius Description
The P0038 diagnostic trouble code (DTC) for a 2006 Toyota Prius indicates an issue with the oxygen sensor heater control circuit on Bank 1 Sensor 2. This sensor is responsible for monitoring the oxygen levels in the exhaust gases after they have passed through the catalytic converter. The heater control circuit is designed to keep the oxygen sensor at an optimal operating temperature for accurate readings. When the control circuit is detected to be operating at a high voltage, it triggers the P0038 code.
