• Emissions test failure tied to improper air-fuel mixture feedback
• Driveability issues on Honda Passport, Isuzu Rodeo, Isuzu Trooper, and related applications

Installation Notes and Tips

Confirm upstream position, connector style, wire count, and thread diameter before installation. Match the original harness length and threaded mounting style to the vehicle’s factory sensor location. For best results, inspect the connector, wiring, and exhaust threads before installing the new sensor on the Honda Passport, Isuzu Rodeo, or Isuzu Trooper application.
