Question about 1999 Lexus ES 300
I'm looking to replace my own mass airflow sensor on a '99 ES 300 w/ variable valve timing. I've been told it's a simple procedure, but I'm not auto saavy and would feel more comfortable getting a walk-through by someone experienced.
The MAF is on the Air Intake above the air filter box and screwed into the plastic tube heading toward the throttle body. It is the 2" by 2" plastic protrution from the air intake tube. There should be two philips screws holding this in. Remove the two screws and back the entire MAF out. There is a wire harness connected, unclip this to remove completely.
If you have money burning a hole in your pocket, go ahead and purchase another MAF for a few hundred clams, or you can spend about $10 and clean it. It's made out of titanium and I doubt it will fail in 10 years. But sometime it does happen.
Go to Lowes, or Home Depot and buy Electronic Cleaner in a spray can. If you look inside the sensor, there is a heated wire, and behind that is another wire which picks up the oxidized air.
Stick the tube which is attached to the electronics cleaner spray can into the cavity where these wires are seen. Continue to spray most of the can onto these wires to remove oxidation build up from the wires. Let it evaporate for a few minutes then hit it again.
Allow the assembly to evaporate complete for about an hour.
In the mean time, take some throttle body cleaner and spray out the throttle body with the valve open. Keep open to let it dry out quicker and clean up the black crud that come out.
Keep you air filter replaced.
Put everything back together and you should be good to go.
