What is motorcycle PO134?
1 Answers
Motorcycle PO134 is the fault code for the front oxygen sensor. Reasons for engine warning light illumination: Most car owners have probably experienced this situation: shortly after refueling, the engine warning light on the dashboard comes on. This is usually caused by filling up with poor-quality gasoline at non-standard gas stations, resulting in incomplete combustion of the air-fuel mixture during engine operation and triggering the engine warning light. While this doesn't affect driving safety, it may cause some degree of harm to the engine. Reasons for oxygen sensor warning light illumination: Modern vehicles are equipped with two oxygen sensors, one before and one after the three-way catalytic converter. The front oxygen sensor detects the air-fuel ratio under different engine operating conditions, while the ECU uses this signal to adjust fuel injection and calculate ignition timing. The rear sensor mainly monitors the performance of the three-way catalytic converter. Therefore, if an oxygen sensor is damaged or its connector is faulty or loose, it can cause the air-fuel mixture to become too lean or too rich, triggering the warning light.
