Purchase precautions

1. Please purchase according to the original OE and OEM numbers of the vehicle. If you are unable to confirm the specific model, please contact us promptly and we will provide guidance within 24 hours. You can also provide the following information about the vehicle in a timely manner (frame number, model year, displacement, engine code, fuel type) so that we can accurately match the appropriate exhaust gas temperature sensor for you. Do not purchase directly without confirming the suitability of the model, as incorrect parts may result in inability to install and use.
2. Before installation, please ensure that the engine and exhaust system are fully cooled down to avoid high temperature burns. When installing, tighten the thread to the specified torque to prevent exhaust gas leakage and signal deviation.
3. After product installation, if there are problems such as engine warning lights, DPF regeneration failure or abnormal temperature signals, please contact us in a timely manner. We will reply within 24 hours and help you troubleshoot and solve the problem.
4. This product is for exclusive use by diesel vehicles with DPF/SCR exhaust aftertreatment systems. Please do not modify or disassemble the sensor probe and connector, as this will affect measurement accuracy and void the warranty.
