Original Nitrogen And Oxygen Sensor For ISUZU 4JZ1 8-98361712-0 0281007490

The oxygen sensor (O2 sensor) monitors oxygen concentration in exhaust gas, sending signals to the ECU to adjust fuel injection ratios for complete combustion and reduced fuel consumption. The nitrogen oxide sensor (NOx/Nitrogen Sensor) detects nitrogen oxide content in exhaust, working with the SCR aftertreatment system to control urea injection, helping trucks meet emission standards like Euro 4, Euro 5, and Euro 6. These sensors are core components of truck exhaust emission control systems. We supply replacement NOx sensors and oxygen sensors for ISUZU, JMC, Qingling, JAC, and other Chinese light-duty diesel trucks.

The most accurate matching basis is the original OE part number of the NOx/O2 sensor. You should also confirm: emission standard, plug pin layout, cable length, thread specification of mounting base, and sensor installation position. Our sales team will match the exact model within working hours.

• Wait for the exhaust pipe to fully cool down before replacement to prevent scalding
• Replace the sealing gasket together to avoid exhaust leakage
• Do not bend or pull the sensor harness violently during installation
• Avoid coating anti-seize grease on the ceramic probe part
• After installation, clear fault codes via diagnostic computer and conduct road test to verify normal signal feedback

Standard neutral export cartons with independent bubble packaging protect precision ceramic probes from shock damage during sea transportation. Custom private labels and branded packaging are available for large bulk orders.
