Out of the frying pan.......

The pipe directly to the ETM can be easily crimped because of its hidden location. That being said I doubt an air leak would give TPS codes so you may want to look at getting a rebuilt ETM or a contactless kit if you're game.

The rebuilt ETM Volvo part number 36050563 has the most updated software for 2001 5 cylinder turbo variants pre-loaded and is usually fitted with a contactless sensor so is good value.

Tonight I'm planning to check the air intake and vacuum systems to see if I can find any leaks, blockages, etc, and re-seat and re-tighten all the connections. If I'm still having issues then my next step will be to look at a replacement ETM.

FCP has the part number you mentioned here:

https://www.fcpeuro.com/products/Volvo- ... 80-8644347

That page mentions (in three places) that a software update or reload is required in order for the unit to function... is that true for some cases and not for others?

YEah - we have kicked this one around here a few times. Mike is certain one part number of ETM comes with software ready to fly, but FCP has communicated to me that an upload is required.

I would plan on a software upload and be pleasantly surprised if you don't have to

Anyone have experience with the XeMODeX rebuild process purchased through FCP? Seems like a good deal compared to the direct price, although they indicate that XeMODeX may find that a "Level 2" repair is needed at additional cost, after evaluating the unit...

This part number has software pre-loaded; whether it's a perfect match to your car is not certain. If you have a Dice/Vida you can view the software level on the old one vs the new one in Network menu then click on the ETM icon after fitting the new one and using the "refresh" command. The 2 bottom software part numbers MUST be a match to the old ETM.

I've fitted four of the 36050563 and one of the 36050564s which is meant for 2002 non turbos. Each of them had software.

If you don't have Dice/Vida you need a garage level scanner to see the programming.

Also once you obtain the ETM simply plug into your loom turn ign to Pos II and see if it powers up. Within 8 seconds it will power down and click off indicating a pairing with the ECM. It would be 90% safe to fit in this case. If it continues to whine it is definitely NOT an ECM match.

Virgin unprogrammed ETMs don't respond in this way. They just seem dead when you plug them in. Besides virgin ETMs haven't been sold by Volvo since 2014 when part numbers were 36001822 and 36001821 were the final new numbers. Everything after these numbers are rebuilds.

Unfortunately FCP don't have ALL the correct answers. It's best for them to say they're unloaded as the chance of a match is about 16 to 1 considering all the engine, year and transmission variants. Besides with the complexity of install on 1999 and 2000 turbo variants you don't want to remove it and reinstall the old one just to get the car started for the trip to the dealer.

Re: Oil pooling in the wells around ignition coils, Permatex 51813 cam sealer

I found last night that the charge air pipe over the engine was not tightened down all the way, thought that might be it... re-tightened it, but the engine was still idling rough. Removed and cleaned the MAF unit with MAF cleaner, still no change.

If I rev it up to 3k rpm and hold it there a while it sounds okay, but eventually it loses speed and then the rpm drops down under 1k and gets rough again... and sometimes will completely stop.

Further diagnostics:

1. Using OBD code reader w/live data, immediately when the engine starts, it throws a P0121 code (TPS). Also when looking at live data, Throttle Position is locked at 20% immediately on engine start. MAF reading was 0.6-0.7, which I believe is normal.

2. Took audio/video of engine startup to idle, followed by rev to 3k rpm, followed by release of accelerator pedal, subsequent drop in rpm, stumble, and stall out (click image to play):

Image

3. Took audio/video of choppy exhaust during rough idle (click image to play):

Image

4. Took audio/video of engine front / timing belt area (click image to play):

Image

The ETM seems to be the logical culprit due to the P0121 code and the throttle reading being stuck at 20%, and since I was having similar issues before doing work on the cam cover. That being said, is it possible to rule out other causes related to the cam cover job such as?

a. Timing belt incorrectly tensioned
b. VVT hub not properly aligned
c. Issue with re-sealed cam cover

My next thought is to remove the ETM, clean it again, and carefully reinstall it and the air inlet pipe and see what happens. The last time the pipe was disconnected and the throttle was out, I had asked my FIL to work on it because I was finishing up work on the timing belt area at the same time. So I didn't personally have my hands on the parts during installation to verify how they were attached. If it does turn out that the ETM is totally borked, getting a replacement would be my next step.

Any other ideas on how to proceed?

Also, was thinking about cleaning the inside of the ETM. I know we've already discussed the dangers of opening the ETM, but one question I had was whether MAF sensor cleaner could potentially work to clean the sensor film inside the ETM, since it's designed to be safe on the thin film of the MAF sensor, and safe on electronics? Or am I off-base with that thought?

Edit: FWIW, also have an updated photo of the engine bay:

Edit: OR, could it possibly be the replacement brake booster vacuum ejector I got from the junkyard after I broke my original one trying to remove it? Causing vacuum issues?

Does the ETM switch on? Have another person switch on ignition to PosII . It should make a characteristic clicking and high pitch whine for 8 secs and then power down with another click. The fact that your reader says stuck at 20% may indicate a dead ETM however you're probably looking at it with engine off?

With engine on live data should show a throttle angle from around 20℅ to around 90% depending where the loud pedal is of course.

A Vida/Dice will allow you to view BOTH throttle angles and allow you to do a sweep test as well as allowing you to access the current firmware level.

If you have current firmware level 9207849 and 30785180 a replacement ETM from FCP will bolt straight in and work.

The ETM does switch on. I actually removed it but left it plugged in, and shot this video while repeatedly turning the ignition to position 2, waiting for it to click off, then shutting the ignition off.

EDIT: Moved to a Google link, hopefully this will make the video play better.

Is this the normal behavior for a properly functioning ETM when energized?


I took a few close up pictures of the unit as well. Not sure if they’re any use for diagnosis or if the condition is an indication of any other problems.

I had to download the video because it wouldn't view however after viewing the footage it looks perfectly normal and doesn't look like it's binding (a push of the throttle flap manually by hand back and forth while it's asleep will tell more than a video will about binding)

P0121 is a sensor one failure and an internal clean can't get rid of this in the pic (you'll need a contactless kit or another wiper film)
