What is the part number of the Toyota MAF sensor?
There isn’t a single universal Toyota MAF sensor part number; the exact code depends on your vehicle’s model, engine and year. To be sure you replace the right part, consult Toyota’s official parts catalog or a dealership with your VIN.
In practice, MAF sensors are model-specific. Toyota sources them from suppliers such as Denso and Hitachi, and the part number changes with each engine family and generation. The most reliable way to confirm is to reference the vehicle’s service diagrams or pull the exact fitment from a parts catalog using your VIN.
Why part numbers vary for Toyota MAF sensors
MAF sensors are not a one-size-fits-all component. Different engines, intake configurations, and generations use distinct sensors and connectors, so each requires its own part number.
How to identify the exact MAF sensor part number
The following steps help you locate the precise Toyota MAF sensor designation for your car.
- Collect vehicle details: year, make, model, engine code, and VIN. This information is essential to narrow the match.
- Inspect the sensor itself for a stamped part number or label. The MAF sensor body often carries the OEM code and supplier information.
- Use Toyota’s official parts catalog or a dealership database by entering your VIN or engine code to pull the exact part number and compatible revisions.
- Cross-check with reliable online parts retailers that show OEM numbers for your exact VIN; ensure you are matching the MAF sensor, not a different air sensor or housing.
By verifying the VIN, engine designation, and sensor label, you can confidently identify the correct Toyota MAF sensor part number for replacement or warranty purposes.
Where to source the official part number and how to replace
Once you have the correct number, you can order the OEM part or a high-quality aftermarket equivalent that lists the same OEM number. If you are performing the replacement yourself, ensure the sensor is clean and reconnected firmly to avoid intake leaks.
- Check the sensor label: most MAF sensors have a stamped or printed part number on the body or on a sticker near the connector.
- Refer to the vehicle’s service manual or the engine bay diagram in the Toyota Parts Catalog for the exact labeling.
- Enter your VIN into Toyota’s Parts Catalog or contact a Toyota dealer to pull the exact OEM part number and latest revision.
- Cross-reference with reputable parts retailers that display OEM numbers and compatibility for your VIN before ordering.
Following these steps ensures you buy the correct MAF sensor for your specific Toyota model.
Summary
The key takeaway: there is no single Toyota MAF sensor part number. The replacement code varies by model, engine, and year. The reliable method is to use your VIN to look up the exact number in Toyota’s official catalogs or through a dealership, then verify the sensor label and cross-check with reputable retailers before purchase.
What is the code for the mass air flow sensor?
The common diagnostic trouble codes (DTCs) for a mass air flow (MAF) sensor are P0100, P0101, P0102, and P0104. These codes indicate a performance or circuit malfunction, such as a dirty sensor, wiring issues, or a faulty sensor itself, leading to problems like rough idling, poor acceleration, or the check engine light turning on.
This video explains the causes and fixes for P0102 code: 44sHVAC Mechanic YouTube · Jun 28, 2024
Common MAF sensor codes
- P0100: Mass or Volume Air Flow "A" Circuit
- P0101: Mass or Volume Air Flow "A" Circuit Range/Performance
- P0102: Mass or Volume Air Flow "A" Circuit Low Input
- P0104: Mass or Volume Air Flow "A" Circuit Intermittent/Erratic
Potential causes
- A dirty or contaminated MAF sensor
- A faulty MAF sensor
- Problems with the wiring or connectors, such as damage, loose connections, or corrosion
- A clogged or dirty engine air filter
- Vacuum leaks in the intake system
- A restricted exhaust, like a clogged catalytic converter

Common symptoms
- Check Engine light is illuminated
- Rough idle or stalling
- Poor acceleration
- Engine running issues
- Black smoke from the tailpipe
- Hard starts
How to address MAF sensor issues
- Inspect and clean: Carefully inspect the MAF sensor and the surrounding air intake system for dirt, oil residue, or other blockages. Clean the sensor with a specialized MAF sensor cleaner if it is dirty.
- Check for leaks: Look for any air leaks in the intake system, which can cause inaccurate readings.
- Replace parts if necessary: If the sensor is faulty or the air filter is clogged, replace the affected parts. Also, check and repair any damaged wiring.
- Clear the code: After making repairs, clear the DTC from the vehicle's computer.
