Oxygen Sensors for Honda CR-V (1997-2001) 2.0L Upstream & Downstream

Direct-Fit Oxygen Sensor Kit for 1997-2001 Honda CR-V

What it Does: The direct-fit oxygen sensor kit replaces aged, fouled factory sensors on the 1997-2001 CR-V to restore closed-loop air-fuel metering, smooth idle, and resolve catalytic converter efficiency diagnostic trouble codes.

The Stock Honda CR-V Sensor Contamination and Response Lag

Over decades of heat cycling, the original zirconia thimbles on first-generation RD1 and RD2 chassis exhaust streams succumb to silica glaze, carbon accumulation, and internal heater element breakdown. When sensors respond sluggishly, the engine control unit struggles to regulate fuel delivery across the B20B and B20Z powerbands. This results in rich fuel trims, unburned hydrocarbon wash on cylinder walls, fouled spark plugs, failed tailpipe emissions tests, and persistent P0130 through P0420 fault codes.

The Engineering Solution

This 2-piece upstream and downstream kit features high-grade stainless steel housings with double-laser-welded construction to isolate the sensing element from thermal shock and road spray. Rapid-heating ceramic elements reach stoichiometric operating temperature in seconds, allowing the ECU to transition out of open-loop cold start rapidly. Each sensor includes perforated diffusion tips, pre-treated high-temperature lead shielding, and factory-pinned 4-pin gray connectors that lock directly into the chassis harness without cutting or repinning.
