Pictures of how I removed and cleaned the Mass Air Flow Sensor on my 87-95 Nissan Pathfinder.
I removed the Mass Air Flow sensor and cleaned the sensor wires. It was super easy. It took about 15 minutes. Did it really help? I don't know. Maybe.
I had been getting some rough idle on startup. Some smart guys on the Nissan 4x4 forum said to clean the MAF. I was nervous to try it for a long time because they worried about breaking those "tiny little wires," and I couldn't find any good pictures of it. So I took pictures while I did it to help the next guy.
But first, lets pay some bills:
The Mass Air Flow Sensor is between the Air Filer and the Intake Manifold on the drivers side of the engine.
The Mass Air Flow sensor is just past the Air Filer Box.
There's the MAF and the electrical connection.
I used my smallest needle nosed pliers to remove this little retaining clip from
the Mass Air Flow sensor electircal connection.
The clip came off the MAF plug.
And I removed the MAF plug.
I not too gently removed the dirt with a copper wire brush.
I removed the screws from the Mass Air Flow Sensor.
I Removed the MAF.
There are those 2 little wires in the MAF.
It looks like each has a little resistor or something on it.
Check out all the sand that made its way into the MAF body.
I wasn't that gentle.
Radio Shack compressed air, Q-Tips, Rubbing Alcohol.
I used 2 Q-Tips. You can see the dirt that came off.
I put the clip on just a little bit,
then I installed the plug,
then I pushed the clip in the rest of the way.
- Next I sold out to make 02¢
so I can fulfill my lifelong dream of owning a 1986 944 with blown head gaskets.
But no minivans!
- Then I finished my beer.
