No the Sacer is fine and giving almost equal Potentiometer 1 and 2 readings. The board is faulty.

The software numbers 0009207849 B and 0009497924 B are outdated (pre 2006) however I don't think a software update at the dealer will fix this one.

If you can't find the same software in the ETM you buy contact Henry (doublebug) here on MVS or find him on Skype and he can help you rewrite the firmware over the internet to the correct matching level.

So after last time, followed your advice and ordered an used ETM from EBAY (one from a 1999 S80), same part number as mine, white labelled one.

...and went for honeymoon for 1 month... my mechanic assembled it, and told me the car was runnig perfectly, apart from a message in DIM "Engine management - Urgent Revision Needed", along with the orange triangle.

When I came back, 3 days ago, tried the car and it really seemed normal: idling perfectly even with A/C on and runnig on LPG... Until I gave it a spin and it "hesitated" around 4500RPM... 2 or 3 times in a row... and then it stoped hesitating, behaved completely normal, and I brought him home to connect to VIDA.





First surprise: Despite the white label, I got a >2006 software... and it works perfectly in my car who had a <2006 version... and had no need to go to the dealer...

The previous codes related to ETM logic board failure were gone, so erased all DTC's and hoped for the best... WRONG!

A couple Km later, hesitation under WOT @ 4500RPM returned (a brief moment of hesitation) and the "Engine management - Urgent Revision Needed" message. It happends both on petrol or LPG, so I guess it's not fuel related...

It didn't hesitate under 4500RPM, it idled perfectly, and so I used it during weekend (boy did I miss this baby)

Today decided to read the codes again:



So I now have a 9150 and a 914F...

Tested the ETM:





At this moment I am inclined to put to use the SACER i have from the failed ETM.. Am I thinking straight?

They say the maximum tolerance for the difference between Sensor 1 & 2 is 13º... I have, according to the ETM test, 11.16 of maximum... Can this be originating the reamaining symptoms?

Thanks in advance for your time and altruism!

The Sacer is unlikely to fix the throttle codes totally 11% is a very high variance. Fit the Sacer to correct the variance.

The codes are the result of mismatching ECM and ETM firmware. You updated the ETM from old fw to new firmware.without updating ECM fw.

You can do this 2 ways;

1) ask Henry to update the ECM version so it matches the new ETM fw (first ask him to look up your ECM fw numbers in his database to see which ETM numbers will match)

2) ask Henry to load the older version fw to the ETM so it matches the ECM fw. The numbers are further back on this post.

Fitted the SACER a couple hours ago! Haven't got the time to connect it to VIDA yet, but will do so tomorrow.

Anyway, drove the car from mechanic and it seemed normal... Even though I didn't get to "squeeze" him very hard... but it Idles perfectly...

In the meanwhile, I have sent pm to double bug and will follow your advice.

Will get back with further developments.

And thanks once again!

[Littlepug4ever]

So, long story short, I contacted doublebug, we scheduled for next week... and then, the day after fitting the SACER sensor the DTC vanished, never to come back until the present day... I haven't yet connected it to VIDA but in the present I'm runnig for ~300 miles without DTC's and with the car behaving absolutely normal... I am tempted to call it "FIXED"...

All in all, given the fact that I had a faulty board to begin with, I managed to work it out with around 200$ (labor included)... Not bad at all...

Thank you, once again, for you precious help. If it weren't for you I would still be messing around with the original board, trying to figure out why the SACER didn't solve the problem...

[precopster]

No probs. Some ECM versions suit both newer and older ETM versions however I haven't taken a note of them while repairing and scanning ETMs. Glad it all worked out

First link doesn't work. Second link has multiple photos. I have fitted more than 50 ETMs with Sacer contactless. The photo I referred to has the magnet on the right. It goes Between the 10mm nut and the large round black plate. However you need to cut the throttle shaft down by around 12mm so the contactless cap can clear.

Look at April 6th 2012 post I made in this thread It IS VERY clear what needs to be done.

The startup voltage with unit at idle must be between 1.25 and 1.55 volts.

This pic explains the fine tuning of voltages if required:

Precopster I read 0.60 Volts full open and 3.90V close to idle,Sacer sensor, do you imagine why?
Voltmeter black on 2 and red on 1 pin of your picture
Voltmeter black on 2 and red on 3 pin 4.85V

[precopster]

What voltage do you get on pin 2 and 4 of the opposite side? You may need to scrape some more putty away to be able to read it.

Your voltages should INCREASE with openings of the throttle and be stable at between 1.25 and 1.55 between pin 1 and 3 with voltage applied to the throttle.

What does she sound like when voltage is applied? Does it do a very fast double click then shut down ?

[Semins]

When read 1 and 3 the Voltmeter show 4.80V stable , close or open ever 4.80V
I will try to hear for clicks.
On pin 2 and 4 I didn't read.

[Semins]

I have a doubt.
When I fit the tps I put on and solder the pins how write on seller's instructions, but there aren't instructions for setting the magnet.
Can I change the position of sensor whit magnet before fit on ?
The idle and full open position are settable or not?
