Volvo Repair Database 00' V70 X/C SE Mass Air Flow Sensor Replacement With Pics...

Post by jpr0204 » Tue Aug 13, 2013 7:40 am

Hi Everyone,

Just wanted to take a moment and post a MAF sensor replacement tutorial with some pictures to help others that may be in need of repair for this VERY COMMON failure part that often results in a one or more trouble codes and poor drivability. I've laid out the tutorial so easily that my 4-year old daughter now knows how to do it. (Plus, she was daddy's big helper with this too.)

Let start by locating the hood release lever inside the car. It is the red handle under the driver side of the dash.

Then, you want to find the seconday hood latch under the hood and pull it toward you to open the hood.

Now for some of you, you will see your complete engine compartment for the first time. (LOL.)

While standing in front of the car looking at the engine, to your right you will see your air cleaner box. Right behind the lid located in the intake hose you will see a cylindrical type sensor with a clamp on it and one connector. This is the MAF sensor.

Next we want to push down on the locking tab to release the connector and pull it away from the sensor. At this time we also want to remove the the small vacuum port with the lines going to it that connect to the air cleaner lid as well, simply pull the clip back and lift the vacuum port off the lid and set it aside. The final step is to loosen the metal band clamp right behind the MAF sensor with a flathead screwdriver.

After removing the connector from the MAF sensor, go back to your air clean lid it is the large shaped lid to the front of the MAF sensor.

Release all the clips around the air cleaner lid by just pulling them away from the lid itself. I believe there are 7 clips in total.

Once you are done removing the vacuum port, MAF connector, loosening the band clamp, and all the clips, the lid and MAF will take some pretty good fighting with to get it to pull out of the air intake hose sensor. What worked for me was to turn the air cleaner lid and MAF to it's side and give a good tug and it came right out.

Once the lid and MAF is seperated from the intake hose the next step is to remove the MAF from the air cleaner lid. Simply remove the 2 T-25 torx screws from the sensor and the sensor will pull away from the air cleaner lid.

Once the MAF is removed from the air cleaner lid, you'll want to compare it to the new replacement one to make sure it is identical.
Volvo 11.jpeg

The next step is to install the new MAF sensor to the air cleaner lid and just SNUG down the T-25 torx screws. You don't want to play Herculies here or else bad things will occur.

Once you get the new MAF sensor bolted in place to the air cleaner lid, the next step is to re-install the lid and MAF back into the air intake hose. You may have to fiddle with it for a couple minutes but it should go back in without a great deal of effort.
Volvo 8.jpeg

Once you the the the lid and MAF installed back in to the intake hose, your next step is re-attatch all the clips to the lid.
Volvo 7.jpeg
Volvo 7.jpeg (37.11 KiB) Viewed 1993 times
The final steps after re-attatching the clips to the lid is to tighten the band clamp around the sensor securely, re-install the vacuum port to the side of the air cleaner lid, then re-install the MAF sensor connector.

If you had any codes stored in the PCM for a MAF fault, now is the time to clear the codes from the PCM with a OBD-II scanner.

AND... You are finished! Now reward yourself for a job well done!

I hope that this tutorial was helpful to all and please feel free to ask any questions or drop any comments along the way.

- Joe :)

This tutorial would be great for my wife as the first steps have eluded her for years now. Getting her just to check the oil requires a tutorial in itself :lol:

You neglected to mention that in many cases it could run like crap for anywhere from 10 seconds to a minute or who while it and the car adjust to each other!

I hear you loud and clear precopster...

I.e.... Wife goes out and buys a brand new car...drives brand new car for 8 years....does absolutely nothing to it maintenance wise in 8 years...8 year old car breaks down for first time....wife says "what a piece of $#%!, I should've never bought this car!"...

Hold on... wait a seconds...car lasts 8 years and over 100K with no maintenace? Seems like the car is a pretty good car to me...

Just sayin... :)

NO NO NO! LOL,

Not my wife, I was just giving an example of the typical woman...

Only thing most of them know is how to put gas in it and turn the key...

It absolutely amazes me how many people in general never even pop the hood to do a weekly 5 minute fluid level check and inspection...

Well we have a coolant level sensor, a brake fluid level sensor, a washer reservoir sensor, the only dangerous one I haven't worked out is why manufacturers continue with a rudimentary dipstick to check oil level.

Surely a oil level warning system could be devised, hey and a fresh oil reservoir (with it's own low level sensor) of a quart in size which automatically tops up engine oil when it falls below a certain level. Does that sound too complex for any engineers out there?

I was speaking to a ex-Volvo mechanic the other day who now works for a Porsche dealership and he reckons the new 911 uses one litre (roughly a quart) for every thousand kilometres travelled.
I wouldn't leave that little baby in the hands of a stiletto wearing chihuahua carrying person.

^^^ +1 JRL,

I'll never forget the time I was working for my local Caddy dealer.

One of our customer's brought their 02' Seville with the 32-Valve Northstar in for a "it's making a slight ticking noise when running."

After pulling the car in the bay, first thing I did was immediately check the oil level... It was down about a quart but it was DAAAAAAARK!

I pulled the drain the out, and NOTHING came out. I looked in the pan with LED light and it was nothing but road tar!

After pulling the AC Delco filter off, I noticed it still had the ORANGE o-ring on it and not the black o-ring. THE ORANAGE O-RING CAME FROM THE FACTORY!

The car had aprrox. 46,000 miles on it and NEVER had an oil change. Though her husband did add to it when it was low...

Long story in short, it had a bottom end bearing going out and she wanted a motor under warranty of course, but Caddy told her to go pound sand and that they wouldn't cover it due to negligent maintenance by the owner...

She did have it fixed at a cost of $7,500 for a new Northstar crate motor...

An expensive lesson learned for sure....

Some of us "women' actually work on their own cars and are ASE Master's, So not ALL women are like that! Just saying! BTW- Thanks for the tutorial. I am replacing the MAF after I clean the E T body and the the contact on the PNP.
