Find out what the Code means before leaving any feedbacks. 1. ONLY a defective sensor after tested by a voltmeter is applied to manufacturer warranty. 2. 20% restocking fee is required if buyer bought wrong items due to not paying attention to fitment information and ask for return. The Price, Quality & Functionality of the O2 Sensor is fully covered under our warranty & return policy. However, refund for any labor cost, expense in a dealer shop or damage due to wrong installation is NOT covered. Q: How do I know the O2 sensor is good or not? A: The only way to know if the O2 sensor is functioning normally is to check its responsiveness to changes in the air/fuel mixture, by Voltage Measurement or Waveform Simulation. Use a 10-mega ohm digital voltmeter. Hook up the voltmeter's red probe to the sensor's signal wire and the black probe to engine ground. (Use back probe method, DO NOT pierce the wire.) For a good sensor, voltage should fluctuate constantly between 0.1 and 0.9 volts after starting the engine for 2 or 3 minutes. Goes above range between 0.1 and 0.9 volt Remains below 0.5 volts Stays fixed at a particular voltage Payment PolicyShipping PolicyReturns PolicyContact UsFeedbackPayment Policy We accept PayPal only We accept Paypal only for the payment, and all orders should be paid through Ebay auction, please do not pay directly to our Paypal account.
