Parts for your 2022 Honda Cr-v-Oxygen sensor

2022 Honda CR‑V Oxygen Sensor — What it does, why it matters, and how to look after it

Yes, the 2022 Honda CR‑V is equipped with oxygen‑sensing hardware. Both the 1.5‑litre turbo petrol and the two‑motor hybrid feature an upstream air/fuel (A/F) ratio sensor (Bank 1 Sensor 1) ahead of the catalytic converter and a downstream heated oxygen sensor (HO2S, Bank 1 Sensor 2) after it. This configuration is used to control fuelling and to monitor catalyst efficiency, making the oxygen sensor directly relevant to servicing and repairs on a 2022 CR‑V in Australia and New Zealand.

Technical sources supporting this fitment:

• Honda CR‑V 2017–2022 Service Manual (Fuel & Emissions, PGM‑FI System): Shows A/F Sensor (B1S1) and Secondary HO2S (B1S2) on L15B turbo and 2.0 hybrid engines.
• Honda Electronic Parts Catalogue for 2022 CR‑V: Lists Air/Fuel Ratio Sensor (front) and Secondary O2 Sensor (rear) by VIN.
• OBD‑II/ADR 79/04 and SAE J1979/ISO 15031: Require closed‑loop control and catalyst monitoring via oxygen sensors.

The oxygen sensor setup in the 2022 CR‑V quietly keeps the engine running sweet as, balancing performance with clean emissions. The front A/F sensor constantly reads the exhaust’s oxygen content so the ECU can fine‑tune fuelling in closed loop. That helps deliver crisp throttle response, decent economy, and minimal emissions whether commuting or touring. The rear HO2S keeps an eye on the catalytic converter’s effectiveness, if the cat isn’t storing oxygen properly, the ECU flags it with a check‑engine light and an emissions fault code.

These sensors are generally service‑on‑condition rather than routine replacement items. In normal Aussie and Kiwi driving, they often last well beyond 160,000 km. That said, high sulphur fuel, silicone sealant vapours, oil consumption, misfires, or exhaust leaks can shorten their life. For any drivability gripes or a fuel economy drop, a quick scan for codes (think P0131–P0139 or P0420) and a look at live data is smart. If replacement is needed, using quality OE‑equivalent parts (commonly Denso/Honda) avoids headaches with heater circuits or slow response. Fitment is straightforward with the right O2‑sensor socket, always repair any exhaust leaks first, avoid contaminating the sensing tip, and tighten to the spec in the Honda service information. Hybrids still rely on both sensors—while the engine runs less, frequent heat cycles mean their condition remains just as important.

• Common signs of trouble: rough idle, sootier tailpipe, higher fuel use, sulphur smells, failed WOF/rego emissions checks, or a lit MIL with O2/catalyst codes.
• Good habits: fix misfires promptly, keep the air filter fresh, use quality petrol, and don’t overuse sealants that off‑gas into the intake.

Professional diagnosis with a scan tool and, if needed, a smoke test gives the best call on whether the sensor or something upstream is the real culprit.

How many oxygen sensors are on a 2022 Honda CR‑V?

Most 2022 CR‑V petrol and hybrid models use two sensors on the single exhaust bank: an upstream air/fuel ratio sensor (Bank 1 Sensor 1) before the catalytic converter, and a downstream heated oxygen sensor (Bank 1 Sensor 2) after it. Market calibrations may vary slightly, but it’s a two‑sensor layout on this generation.

What are the symptoms of a failing oxygen sensor on this model?

Drivers may notice poorer fuel economy, a hesitant feel off the line, rough idle, or a sulphur/“rotten egg” smell. The check‑engine light often appears with codes like P013x (sensor circuit/performance) or P0420 (catalyst efficiency). Exhaust leaks can mimic sensor faults, so proper testing is important.

When should the oxygen sensor be replaced?

There’s no fixed interval in the Honda schedule, it’s replaced on condition. Many last past 160,000 km, but contamination, misfires, or ageing heaters can bring that forward. If diagnostics show a slow or biased sensor, or if the heater circuit fails, replacement with an OE‑quality unit is the go. Always address any misfire or leak first so the new sensor isn’t compromised.
