\"\"<\/p>\n

This automotive maintenance tutorial was specifically written to assist owners of the second generation (2017, 2018, 2019, 2020, 2021 and 2022) Mazda CX-5 SUV in checking, cleaning or changing the mass air flow (MAF) sensor for the SkyActiv-G 2.5 liter inline four cylinder engine.<\/span><\/p>\n

(The procedure should be the same or very similar for the turbocharged 2.5L I4, the 2.0L I4 and the SkyActiv-D 2.2L I4 diesel twin turbo engines.)<\/span><\/p>\n

Owners of other Mazda vehicles such as the CX-3, CX-30, CX-7, CX-9, Mazda3, Mazda6, MX-30, MX-5 Miata, Mazda2, CX-4, CX-8 and BT-50 may also find these DIY instructions to be helpful.<\/span><\/p>\n

The OEM (original equipment manufacturer) mass air flow sensor part number is\u00a0Mazda PYFS-13-215<\/a><\/b>\u00a0(also known as PYFS13215 or PE01-13-215).<\/span><\/p>\n

Two compatible replacement aftermarket MAF sensors with their part numbers are as follows:\u00a0Standard Motor Products MAS0517<\/a><\/b>\u00a0and\u00a0WVE 5S15707<\/a><\/b>.<\/span><\/p>\n

A few of the most common symptoms of a dirty, failing or faulty MAF sensor include hard starting, rough idling, hesitating, surging, poor acceleration, hiccups, low fuel economy (reduced MPG), stalling, loss of power and misfiring. You might also see a CEL \/ SES (check engine light \/ service engine soon warning) displayed on the gauge cluster.<\/span><\/p>\n

If you have an\u00a0OBD2 scan tool<\/a><\/b>\u00a0it should reveal a MAF sensor related DTC (diagnostic trouble code) such as P0100, P0101, P0102, P0103 or P0104.<\/span><\/p>\n

It’s also a good idea to check for other issues that may produce similar symptoms such as a vacuum leak from a split rubber hose, a clogged engine air filter, a cracked plastic intake tube, a leaking intake manifold gasket and a faulty PCV valve.<\/span><\/p>\n

The first two steps are to open the hood and move to the right (driver) side of the engine bay.<\/span><\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

The MAF sensor is located on the top of the engine air filter housing’s plastic air intake tube attached to the rubber air intake hose.<\/span><\/p>\n

If you’d like to try cleaning the old sensor before you purchase a new one, I recommend using some\u00a0CRC Mass Air Flow Sensor Cleaner<\/a><\/b>\u00a0spray.<\/span><\/p>\n

The only tool needed to remove and replace the sensor is a standard Phillips head screwdriver.<\/span><\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

Remove the two screws by turning them in the counterclockwise direction with the Phillips head screwdriver.<\/span><\/p>\n

Set the two screws aside in a safe place.<\/span><\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

Rotate the old sensor back and forth a few times to make sure the rubber o-ring gasket is not stuck to the plastic air intake tube.<\/span><\/p>\n

If you just pull the sensor straight out, the old brittle o-ring might tear apart and allow pieces of rubber to fall into the air intake assembly.<\/span><\/p>\n

Once the sensor is loose, gently lift it out of the port (opening) in the air intake.<\/span><\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

Inspect the old sensor for any soot, oily deposits, other debris or any damage.<\/span><\/p>\n

To clean the old sensor, gently spray into every opening with some\u00a0CRC Mass Air Flow Sensor Cleaner<\/a><\/b>.<\/span><\/p>\n

Do not spray cleaner into the electrical contacts.<\/span><\/p>\n

To clean the electrical contacts on the sensor or the power plug, use some\u00a0CRC Electronic Cleaner<\/a><\/b>\u00a0spray.<\/span><\/p>\n

The OEM (original equipment manufacturer) sensor in this 2019 CX-5 was marked as part number Mazda PYFS E5T63271 K6266 9327 (Philips K6266 9327).<\/span><\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

Line up the new sensor with the opening in the air intake tube.<\/span><\/p>\n

Lower the new sensor down into place and line up the two screw holes.<\/span><\/p>\n

Spin in the two Phillips head screws a few turns with your fingers to help prevent them from falling down into the engine bay and becoming lost.<\/span><\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

Tighten the two screws in the clockwise direction until they are snug.<\/span><\/p>\n

Try to avoid over tightening the screws to prevent from cracking the plastic sensor housing or the air intake tube.<\/span><\/p>\n

Push the power plug straight on to the base of the new sensor.<\/span><\/p>\n

You should hear or feel the electrical connector “click” securely into place.<\/span><\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

If you have an OBDII scanner, clear any MAF sensor related DTC codes.<\/span><\/p>\n

Start the engine and listen closely for any strange sounds. If you do hear any weird noises, immediately turn off the ignition and double check your work.<\/span><\/p>\n

If everything sounds normal, take the car for a short and careful test drive to see if any of the symptoms of a faulty MAF sensor occur again.<\/span><\/p>\n

Don’t forget to write down the sensor change in your SUV’s service records.<\/span><\/p>\n
