FITMENT
Compatible with Toyota diesel vehicles equipped with SCR (Selective Catalytic Reduction) AdBlue emission systems requiring NOx monitoring.
Common applications include:

• Toyota Fortuner 2.4D / 2.8D (2020–2022 SCR diesel variants)
• Toyota Hilux Revo 2.4D / 2.8D (2020–2023 SCR diesel variants)
• Toyota Land Cruiser Prado (some SCR diesel configurations depending on market)
• Euro 5 / Euro 6 diesel emission systems with AdBlue technology

Using reference numbers:

• 89463-71040 (Toyota OEM part number)
• SCR NOx sensor system for Toyota diesel aftertreatment
• Equivalent NOx sensor module depending on calibration/region

This sensor is part of the exhaust aftertreatment system and monitors nitrogen oxide (NOx) levels to control AdBlue injection for emissions compliance.

FAQ
Q1: What is the function of this NOx sensor?
A1: It measures nitrogen oxide (NOx) levels in the exhaust system and sends data to the ECU to regulate AdBlue/DEF injection and reduce emissions.

Q2: Where is it installed?
A2: It is installed in the SCR exhaust system, usually before or after the catalytic converter depending on vehicle configuration.

Q3: What are symptoms of failure?
A3: Check engine light, SCR/AdBlue warning, NOx sensor fault codes, reduced engine power, or limp mode activation.

Q4: Is 89463-71040 interchangeable with other Toyota NOx sensors?
A4: It may have close cross-references within Toyota SCR systems, but compatibility depends on VIN, engine type, and ECU calibration.
