The 2002 Toyota Camry uses an electronic fuel injection system to deliver precise amounts of fuel to the combustion chamber, with split-second precision. Proper air induction is necessary for the fuel to burn. The amount of air determines the amount of fuel necessary to create optimal combustion. A mass air flow sensor measures the amount of air brought into the engine and supplies that information to the onboard computer, which then uses that information to regulate the fuel delivery process. If the MAF reads inaccurately, engine performance and fuel economy will suffer greatly.
Instructions
- 1
Shut the Camry's engine off and open the hood. Unlatch the air cleaner assembly lid. Unplug the mass air flow sensor engine harness connector from the side of the sensor.
2Loosen the clamp that holds the air cleaner assembly outlet tube to the MAF sensor, using a Phillips screwdriver. Loosen the clamp between the mass air flow sensor and the engine, using the Phillips screwdriver.
3Lift the air cleaner assembly lid out of the way. Pull the old MAF sensor out of the Camry's engine compartment and set it aside.
4Set the new MAF sensor in place. Slide the MAF outlet tube onto the new MAF sensor. Lower the engine air cleaner back into place and latch it onto the air cleaner base.
5Slide the engine air cleaner outlet tube onto the new MAF sensor. Tighten the clamps, using the Phillips screwdriver, after you've verified that the tubes seat properly on the MAF, with no air leaks visible.
6Plug the engine harness into the Camry's new MAF sensor. Close the Camry's hood.
