Special instructions
1、About replacement：
Before replacement, please go to the [professional maintenance shop] to confirm whether the oxygen sensor has a fault. To replace the oxygen sensor, you need to check whether the three-way catalyst and other circuit systems have a fault. If the three-way catalyst and circuit system have a fault, you can’t solve the fault code of the instrument by replacing the new oxygen sensor. If the three-way catalyst has a fault, the data monitored by the oxygen sensor will also be affected by the three-way catalyst, resulting in abnormalities, Please check the cause of the failure before purchasing.
2、About Installation
Personal installation is not recommended because there are many professional parts and skills involved. It is recommended to install them in a professional repair shop. Before installation, it is recommended to clean the three-way catalytic converter. After installation, make sure to use the repair computer to clear the original fault code. The new sensor data is more accurate and sensitive, which is very good for the car.
3、About returns
As this product is a precision part, once installed, it will affect the secondary sales. All oxygen sensors sold in this store do not support trial use. Please be sure to confirm whether the purchase is correct.
Due to the incomplete inspection of the vehicle fault, it was only after the replacement of the new oxygen sensor that it was found that the fault of other components. For example, the replacement of the detection instrument still showed the fault of the oxygen sensor, but in essence it may be caused by the damage of the circuit of the sensor link or the fault of the three-way catalytic converter. We have the right to refuse your refund and return application. Please understand.
4、About Delivery
As this product is a special accessory, it needs to match the model, year, displacement, working position and other professional information of the car. In order to check the accuracy, you need to provide the vehicle identification number (VIN) to match you with the accurate OE information.
※ If you do not provide accurate matching information to order directly, we will ship the products selected in your order directly. We will not assume the responsibility for any dispute caused by your wrong purchase.
Where is the VIN located?
On a majority of vehicles, you’ll find the VIN on the lower corner of the driver’s side dashboard. It will likely appear as a metal plate or sticker with the code engraved or printed on it. If you don’t find the VIN on the dashboard, it might be on the driver’s side door where it latches or in the glovebox.
Off the vehicle, you can find the vehicle identification number on a variety of papers associated with your vehicle. The VIN will be prominently displayed on your vehicle’s title, registration and insurance paperwork.

The theoretical air-fuel ratio output is abnormal (too high): P0132, P0138, P0152, P0158；
Fault codes that are not within the warranty scope (do not return or replace if they are not resolved after replacement), ternary catalytic fault codes, fuel fault codes (too lean or too rich): P0420-P0423, P2271-P2278, P0171-P0175, P2297-P2298, P2096-2099；
Fault code B1 is group 1, B2 is group 2, oxygen sensor 1 is front oxygen, and oxygen sensor 2 is rear oxygen；
(S1=front) (S2=rear) (B1=1 group) (B2=2 group) Just look at S？
