Parts for your 2022 Toyota Land cruiser-Maf sensor

2022 Toyota Land Cruiser MAF sensor

Yes, the 2022 Toyota Land Cruiser (300 Series) uses a MAF sensor. Technical references that confirm this include the Toyota Electronic Parts Catalogue (EPC) for LC300 variants (FJA300 petrol V35A‑FTS and VJA300 diesel F33A‑FTV), which lists a “Mass Air Flow Meter Assembly,” the Toyota Repair Manual for Land Cruiser 300 that includes DTCs P0101–P0104 for the MAF circuit, and Techstream live data items showing MAF readings in g/s. DENSO’s application catalogues also list a compatible MAF meter for LC300 models.

On the 2022 Land Cruiser, the MAF sensor’s job is to measure the actual mass of air entering the intake so the ECU can match fuel precisely. That accuracy underpins smooth cold starts, clean idle, solid throttle response and the right fuelling under boost. On the diesel, the MAF reading is also used to manage EGR flow and emissions, on the twin‑turbo petrol, it helps the ECU keep mixtures on point as the turbos spool. It lives just downstream of the air filter housing in the intake duct under the bonnet, making it quick to access.

As part of regular servicing, there’s no scheduled replacement for the MAF on a 2022 Land Cruiser, it’s a “check and keep clean” item. If the vehicle sees dusty outback roads, towing duty, or lots of short trips, it’s worth inspecting the airbox seal and filter at each service and giving the MAF a gentle clean when contamination is suspected. Only use a dedicated MAF cleaner, don’t touch the sensing element, don’t use carb/brake cleaner, and let it dry fully before refitting. Symptoms of a crook MAF include rough idle, hesitation, poor fuel economy, soot on diesels, a MIL/engine light, or limp‑home with codes like P0101. If that’s happening, rule out air leaks and a clogged filter first, then test/replace the sensor.

Replacement is straightforward: ignition off, disconnect the plug, undo the screws, lift the meter out, and fit the new unit with the O‑ring seated correctly. Avoid over‑tightening. After refit, it’s good practice to clear any stored codes and confirm the MAF g/s values and fuel trims with a scan tool. Using a genuine or OE‑quality DENSO unit avoids headaches, and checking the crankcase breather and intake for oil mist keeps the new sensor happier for longer.

• Service tip: after water crossings, inspect the air filter and housing to prevent moisture or dust ingestion hitting the MAF.
• Typical check interval: eyeball at each service (10,000–15,000 km), clean only if needed.

Popular questions

Does the 2022 Land Cruiser actually have a MAF sensor?
Yes. Both the petrol V35A‑FTS and diesel F33A‑FTV LC300s are fitted with a mass air flow meter. This is reflected in Toyota’s EPC and Repair Manual, and it shows up in Techstream as a live MAF reading with corresponding MAF‑related DTCs.

How often should the MAF sensor be cleaned or replaced?
There’s no set replacement interval. On a well‑sealed intake with clean filters, the MAF can last years. Inspect at regular services and only clean if contamination is suspected. Use proper MAF cleaner and avoid touching the element. Replace if it’s out of spec or throwing repeat MAF codes after leak checks.

Where is the MAF sensor located on the LC300?
It’s mounted in the intake duct just after the airbox under the bonnet. On right‑hand‑drive models it’s easy to spot near the air filter housing, secured by a couple of screws with a single electrical connector.
