BDFHYK Oxygen Sensor Upstream Downstream O2, Compatible with Mitsubishi Eclipse Cross Lancer Outlander Outlander Sport RVR l4 1.5L 2.0L 2.4L, 18074, 1588A141 Replacement 1PCS

This BDFHYK O2 sensor is an OE-style aftermarket replacement for verified Mitsubishi Eclipse Cross, Lancer, Outlander, Outlander Sport, and RVR applications that cross-reference 18074 and the listed OE numbers. Sensor position varies by application, so do not order from vehicle name alone. Confirm the exact year, engine, original sensor number, exhaust location, connector, wiring layout, lead length, and emissions configuration before installation. A stored code or Check Engine Light alone does not prove sensor failure.

18074 O2 Sensor Interchange References

18074 Mitsubishi Sensor Position Check

This product can be used in different upstream or downstream positions depending on the verified application. Do not assign a universal Bank 1 Sensor 1, Bank 1 Sensor 2, Bank 2 Sensor 1, or Bank 2 Sensor 2 label. Match the removed sensor and vehicle-specific service information.

18074 O2 Sensor Diagnosis Before Replacement

Inspect the connector, wiring, heater circuit, related fuse, power and ground, exhaust leaks, intake or vacuum leaks, fuel pressure, injector operation, misfires, and catalyst condition before replacing parts. Fuel-trim and catalyst-efficiency codes require system diagnosis.

18074 O2 Sensor Installation Notes

• Allow the exhaust system to cool before service.
• Use an O2 sensor socket or suitable wrench.
• Compare the replacement connector, lead length, and OE reference with the removed sensor.
• Inspect bung threads and start the sensor by hand.
• Use anti-seize only when permitted by the sensor instructions.
• Tighten to the applicable service specification and route the harness away from heat and moving parts.
