ETM Happily Ever After

Post by PixelDust » Sat May 23, 2020 5:25 am

May 22nd, 2020.

Hey there, everyone.

My story is that of the Electronic Throttle Module (ETM).

Topic of conversation:
‘01 Silver Mystic Metallic, XC-70 w/201,004 miles.

Purchased in July 2019 for $500 w/191k.

The previous owner bought it new. Maintained well, but he complained of a slipping transmission, though this current transmission was rebuilt at 120k (Aisin 55/50) He provided all the records, and at 190k had the timing job done as well.

He had a brand new XC-60 in the driveway, and a lovely red 850 Turbo Sedan of the late 90's vintage in fantastic shape. This nice fellow needed parking space, and I was the lucky one to respond to his Advertisement first..

I drove it home. I noticed hesitation between 2nd/3rd on medium to heavy acceleration (A flare one might call it.) This I imagine, the slipping trans the previous owner thought he had. I have a Blue Point EECR5, scan tool that is fairly Volvo friendly (scans and clears ABS, SRS, Trans, Ecm, Live Data, OBD2.et. codes were:

P303- Cylinder 3 Misfire
9150- Unknown fault. Scan tool read this, but couldn’t give details.
91F0- Unknown.
There were a few others, but none affecting drivetrain. No transmission codes either. I of course had my introduction to what these unknowns were, the ETM. The ‘10 years extended, or 200k, whichever came first, back in ’06’warranty service on faulty modules.
- I gave her a fresh synthetic oil and filter change (which I’ve since done 4 more times)
- Trans drain and fill with those oil changes. (My strategy here includes Lucas Oil Stop/Slip, and Seafoam TransTune in combination each time). Shifts great, fluid smells and looks New.
- New plugs Iridium Bosch
- Bosch coil packs New
- Power Steering Service
- Both Diff. Services.
- Replaced a dented door with one from a 2001 S80. I posted on that topic. Link to that post:

viewtopic.php?f=9&t=91917




I got around to the PCV system, installed new injectors, and cleaned the ETM (which was/is the Magnetti Marelli/Yellow aftermarket module). But, 91F0 and 9150 remained permanent companions. All along I had the same symptom, the hesitation in acceleration. The codes are for an internal fault. Replacement my only option.

The cost prohibitive nature of buying a remanufactured unit from Xemodex, then Volvo's Vida charge for the software, enabled me to ignore the issue. I was looking at $700-$1,000 in my area to take care of the problem with certainty.

Now, the rumor is/was that if you get an ETM froma vehicle that’s your model/year, odds are in your favor that it won’t require programming. My attention went to the salvage yards. Waiting for my Silver Mystic Metallic Unicorn with a good throttle module, to appear. It did yesterday.

I installed it today. It’s the same Magnetti Marelli unit. The serial numbers were:
8644347 For the salvage unit
8644346 for the faulty unit.

The car started right up after installImage. No codes, no programming necessary.. Drives great. Feels like a newish car. Lots of power. Has a pop it didn’t have before.

That’s the my story on the XC-70. Very happy about it, and wanted to share.

Do the mod yourself its easy, cant say it did much on my car because the original ETM seemed to be working. The VIDA ETM test gave me a very good score. from memory it was around 1% variation

Do you know anything about the donor car mileage? The MTBF on the MM is about 150k+, so that will give you an indicator

Once you start getting codes, you have about 10,000 miles before hard limp mode, in my limited experience

You beat 5:1 odds getting that donor to bolt in and work without software , well done

Adding on. I searched, but could not find, The discussion on the later MM throttles. After 2005-6 I believe the replacements were more robust, or perhaps I’m making this up.

I have about 120k on my replacement MM Body on my T5

The MM from my 99 NA, now gone , went 200k and is in operation on another car still.

I was lucky and found a Xemodex at the bone yard 👍

There is a glossary in the major topics sticky but my apologies for by bad acronym habit

Mtbf,,,mean time between failure, engineer speak for lifetime
MM ,,.a nice candy , or magneti Marelli company ( maker of the early throttle body)

Hey, guys. Thanks for the replies.

The donor vehicle's age is unknown. It's a good question, and one I pondered, but had no immediate way of knowing. I'll be going back to that salvage yard this week, so I'll see if I can get the mileage number one way or another.

Though I have most of the repair records on my T-5, no mention of the MM install can be found. So I wonder, was it installed after '05-06? How far did it go on that MM before it started to fail at around 190k....I may be able to get this info from the original owner, then again, I don't want to be a bother.

120k and running on your MM TB, abscate. That gives me a glimmer of hope that I'll get some good use out of my donor find, even if it was well used. I'll let you know what info I can gather. .

What a valuable resource this forum is for DIY Volvo owners. Thanks again!

The date code on your unit says

01W05 which means 2001, week 5 , so it’s about 20 years old. Miles are more important than age
