Parts for your 2022 Toyota Camry-Oxygen sensor

2022 Toyota Camry Oxygen Sensor

Yes, the 2022 Toyota Camry uses oxygen-sensing hardware. Technical sources including Toyota’s Repair Manual (TIS) for the XV70 series and the Toyota Electronic Parts Catalogue specify an upstream air–fuel ratio (A/F) sensor and a downstream heated oxygen sensor (HO2S) on all petrol variants, including Hybrid (A25A-FXS) and non‑hybrid 2.5‑litre (A25A-FKS), V6 models (2GR‑FKS) have one set per bank. Emissions regulations under OBD‑II/ADR 79 and equivalent NZTA requirements also mandate catalyst monitoring via upstream and downstream sensors.

On the 2022 Camry, the upstream wideband A/F sensor constantly reports how rich or lean the engine is running so the ECU can trim fuel precisely. The downstream HO2S checks catalytic converter efficiency and helps the ECU verify that emissions are kept in check. Together, they keep fuel economy sharp, drivability smooth, and the tailpipe clean.

There’s no fixed replacement interval listed by Toyota, but these sensors are wear items. In local conditions, many will last well past 160,000 km, though contamination (coolant, oil, silicone vapours) or exhaust leaks can shorten life. If the check engine light pops on with codes like P0136–P0138 or P0420, fuel use climbs, or the car feels a bit doughy, an oxygen sensor or its wiring could be on the cards.

When servicing a 2022 Camry, it’s smart to include quick checks around the sensors: look for chafed wiring, cracked connectors, or soot marks hinting at exhaust leaks. If replacement is needed, go for quality OEM-equivalent parts (Toyota/Denso). Fit the sensor to the correct bank and position (Bank 1 Sensor 1 = upstream A/F, Bank 1 Sensor 2 = downstream HO2S on the 4‑cylinder, V6 has Bank 1 and Bank 2). Most new sensors come pre‑coated—avoid extra anti‑seize unless specified by the manufacturer, and use the correct 22 mm O2 socket to prevent damage.

After installation, clear fault codes and complete a short drive cycle so the ECU can relearn trims and set readiness monitors—handy before a WOF/regos check. For owners who like data, a scan tool can confirm an actively switching downstream sensor and a stable upstream wideband signal during cruise. Keeping the engine in good nick, using quality petrol, and fixing any misfires early will help the oxygen sensors go the distance.

• Common signs: higher fuel use, rough idle, sulphur smell, failed emissions, MIL on with O2/A/F or catalyst codes.
• Good practice: fix exhaust leaks first, check for oil/coolant contamination, and verify proper sensor heater power and grounds.

How many oxygen sensors does a 2022 Camry have?
Most 2.5‑litre models have two: one upstream A/F sensor and one downstream HO2S on the single exhaust bank. V6 models have four—one A/F and one HO2S per bank. Hybrids still run two on their single bank because the petrol engine needs closed‑loop control whenever it’s on.

Can an oxygen sensor be cleaned, or should it be replaced?
Cleaning generally doesn’t work. The sensing element is delicate, and contamination embeds in the ceramic. If diagnosis points to a lazy or failed sensor, replacement is the reliable fix. Always address root causes—like rich running or oil burning—so the new sensor isn’t fouled again.

Is it safe to drive with a faulty oxygen sensor?
Short term, the Camry will usually default to richer fuelling, so it’ll run but use more petrol and may risk catalyst damage if left too long. Best to sort it promptly to protect the cat, keep fuel economy tidy, and pass emissions checks.
