FAQ

Q1: Is this compatible with all ISUZU trucks?
A1: No, compatibility depends on engine type, emissions standard, and SCR system layout.

Q2: Are 5WK96738B and 89830-23930 the same part?
A2: Yes, they are cross-reference numbers for the same NOx sensor used in ISUZU SCR systems.

Q3: Where is it installed?
A3: It is installed in the exhaust system to measure nitrogen oxide levels for SCR (AdBlue) control.

Q4: What does this sensor do?
A4: It monitors NOx levels in exhaust gas and helps the ECU control AdBlue injection for emissions compliance.
