Parts for your 2013 Toyota Land cruiser-Oxygen sensor

2013 Toyota Land Cruiser oxygen sensor: what’s fitted, what it does, and when to replace it

Short answer, based on Toyota service literature and parts catalogues for the 200 Series: yes, oxygen sensing is used on 2013 Land Cruiser petrol models (URJ200/3UR-FE or 1UR-FE), which run wideband air–fuel ratio (A/F) sensors upstream and heated oxygen sensors (HO2S) downstream of the catalytic converters. These are listed in Toyota’s workshop manuals (TIS) and Electronic Parts Catalogue for those VINs. For the 2013 Australian and New Zealand diesel V8 (VDJ200/1VD‑FTV), an oxygen sensor is typically not fitted, Toyota’s diesel engine documentation for that year shows exhaust gas temperature sensors, mass air flow and pressure sensors handling mixture and aftertreatment control instead.

For petrol owners, the oxygen sensor setup is a quiet workhorse that keeps the big Cruiser running sweet and legal on emissions. The upstream A/F sensors (Bank 1 Sensor 1 and Bank 2 Sensor 1) constantly feed the ECU precise data so it can hold the mixture near stoichiometric for clean burn and good fuel economy. The downstream HO2S units (Bank 1 Sensor 2 and Bank 2 Sensor 2) monitor catalytic converter efficiency and help the ECU spot catalyst issues before they become expensive.

There’s no hard-and-fast replacement interval in Toyota’s scheduled servicing, but in the real world these sensors are wear items. By 160,000–240,000 kilometres they can slow down or drift out of spec, nudging the mixture rich, upping fuel use and triggering fault codes (think P013x range). If the check engine light pops up, the idle’s a bit rough, or the Cruiser’s chewing through more litres per 100 km than usual, it’s worth scanning the ECU and looking at fuel trims and sensor response times.

• When replacing: use quality OEM or equivalent wideband A/F sensors for the upstreams, and the correct HO2S for the downstreams—banks and connector styles matter.
• Spark the old sensors out with a 22 mm O2 socket once the exhaust is cool, a dab of the specified anti-seize (if called for by the sensor maker) on the new threads helps next time.
• Clear codes and perform an ECU relearn or battery-off reset so trims settle quickly. A short road test with live data confirms all is well.

Diesel owners, take note: on most AU/NZ 2013 VDJ200s, an oxygen sensor isn’t used. The 1VD‑FTV manages fuelling via MAF/MAP inputs, EGR control and exhaust temperature feedback, some later models gained extra aftertreatment hardware, but a traditional O2 sensor isn’t part of the 2013 diesel’s setup.

Popular questions

Does my 2013 Land Cruiser actually have an oxygen sensor?
Petrol models do—two upstream A/F sensors and two downstream O2 sensors. The 2013 AU/NZ diesel VDJ200 generally doesn’t have an oxygen sensor at all. If unsure, check the VIN/engine code or look for sensor bungs ahead of and after the catalytic converters on a petrol exhaust.

How often should oxygen sensors be replaced on a 2013 Land Cruiser?
They’re not a scheduled service item, but many get tired around 160,000–240,000 km. Replace when there are fault codes, lazy response on a scan tool, poor economy, or catalyst efficiency warnings. Proactive replacement of upstream A/F sensors at high kilometres can restore crisp running and save fuel.

Is it OK to keep driving with a dodgy oxygen sensor?
Short trips won’t strand the vehicle, but it can run rich, drink more fuel, and risk premature catalyst damage. Sort it sooner rather than later to avoid bigger bills and to keep emissions in check.
