Where is the part number on a MAF sensor?
The part number on a mass air flow (MAF) sensor is typically located on the sensor housing or the wiring harness connector. This information is crucial for identifying the correct replacement part when your MAF sensor needs to be serviced or replaced.
Understanding the MAF Sensor
The MAF sensor is a critical component in the engine management system of a vehicle. It measures the amount of air flowing into the engine, which helps the engine control unit (ECU) determine the correct fuel mixture for optimal performance and efficiency. The part number on the MAF sensor provides important information about the specific make, model, and year of the vehicle it was designed for.
Locating the Part Number
The part number on a MAF sensor can be found in one of two main locations:
- On the sensor housing: The part number may be printed, stamped, or engraved directly on the metal or plastic housing of the MAF sensor.
- On the wiring harness connector: The part number may be printed on the label or tag attached to the wiring harness that connects the MAF sensor to the vehicle's electrical system.
It's important to carefully inspect both the sensor housing and the wiring harness connector to ensure you locate the correct part number. This information will be crucial when ordering a replacement MAF sensor to ensure it is compatible with your vehicle.
Tips for Identifying the Part Number
- Refer to your vehicle's owner's manual or service documentation to find the specific part number for your MAF sensor.
- If the part number is not visible on the sensor or wiring harness, you may need to consult a repair manual or contact the vehicle manufacturer for assistance.
- Be sure to take a clear photograph of the part number and any other identifying information on the MAF sensor to reference when ordering a replacement.
Knowing where to find the part number on your MAF sensor is essential for ensuring you get the correct replacement part when it's time to service or replace this critical engine component.
How do I reset my MAF sensor after changing?
Resetting the MAF Sensor by Disconnecting the Battery
- Remove your old MAF sensor with a screwdriver and remove it.
- Disconnect the battery's negative terminal for 10 minutes.
- Replace or clean your MAF sensor and install it.
- Reconnect the battery, start the car, and clear any error codes.
What is the code for MAF sensor?
P0101
Error code P0101 indicates that there is an issue with your mass airflow sensor (MAF). In this case, the MAF is out of its intended range. Other codes ranging from P0100-P0109, P0505-P0507, and P2096-P2099 often appear simultaneously with this code, given their similar proximate causes.
Can you drive with a bad mass air flow sensor?
Although in some cases, you may technically be able to continue driving with a bad MAF sensor, you should address the issue as soon as possible. A faulty MAF can damage other parts of your vehicle, such as the catalytic converter. What's more, some cars won't even run when the MAF fails.
What is the part number of the Toyota MAF sensor?

Are MAF sensors universal?
Universal-Fit Mass Air Flow Sensor:
This style fits hundreds of applications but you still need to confirm your application before purchasing. This style is recommended if your vehicle already has a universal-fit MAF sensor in it or if you are looking for a more cost-effective option.
Are MAF sensors interchangeable?
Different sensors can even have same connector and still have different voltage to air flow ratio. In reality there are some that can be used like that. Including some where you take sensor part out of housing to swap and it's the difference in housing that makes the calibration.
What are the two types of MAF sensors?
There are two common types of mass airflow sensors in use on automotive engines. These are the vane meter and the hot wire.
Where is the part number on a mass air flow sensor?
Part number location
The part numbers that you need are located on the outside of the housing/tube. Pierburg mostly start with 7. If you see PBT-GF30 on the housing/tube then the number you need will be on the opposite side to this.
What happens if you use the wrong MAF sensor?
Acceleration Lag
If a misreading from the MAF sensor tricks the ECU into putting too much air into the combustion chamber, your vehicle's acceleration will lag. This is because it has more air than fuel and, consequently, it is fuel-starved.
How do I find my MAF sensor?
A: The mass air flow (MAF) sensor, when equipped, is usually located between the air filter box and the intake hose. It's usually visible as soon as you open the hood, but you may need to remove some electrical connections and the air filter box itself to access the sensor.
