Do you have a failing Electronic Throttle Module? What steps to take if you do, plus the latest ETM news. Volvo 1999-2002 models only please.

Oil change reminder light can be reset by use of trip meter and key......just Google it.

Vida/Dice system or a good OBDII scanner such as Carsoft i906 or an Autel AL619 will reset the airbag system...better do it if you want the safety that a Volvo offers :D

Vida/Dice can do both the above operations

Yeah I was really on the fence of getting a vida/dice but I would had need the unit + a laptop. I know its the ideal situation for a volvo, I got a OBDII it delete codes but I don't think it reset the airbags or it reset it and the thing comes back :S

Unless your scanner can actually view SRS codes during reading of the vehicle it won't be attempting to clear them either.

Hi,
I have carried out this repair using a sacer unit after having ECM-91B7 and ECM-9150 codes from the car. I also had 'engine system service required' message on the dash.

Long story short- after much messing about changing car battery and taking the throttle apart again to calibrate, all codes are gone and the car runs ok. However, I have noticed when the car starts on a cold engine, the revs are slow to return to tick over. For example, if I put my foot on the accelerator and take the car up to say 3000 rpm and then take my foot off the accelerator, the car will stay there for a few seconds before slowly returning to tick over.

I only calibrated the throttle yesterday and am wondering if it takes a little time for the unit to settle in. Your thoughts and suggestions eould be appreciated.

Thanks

Hello
I have a weird problem after replacing TPS with sacer. First time I didn´t check voltages, and the ran very badly. So I opened it up again and adjusted voltages. I set it to 1.3V Sacer end with 1.296V on sensor 1 and the black lead showed some 0.03V higher than sacer voltage.I glued everything back up and tested, worked fine for about 15 minutes then suddenly it started running badly again and fault code ETM-9150 (sensor 1).
I opened it up once again and adjusted the voltage to 5 mV from value at original sensor, put it on the car and tested it and it ran great! glued everything back up, used the car normally and after about 4 shorter trips (about 15 minutes each and up to an hour in between trips) It started running badly again.
I tested the ETM with VIDA, and first it reported only a difference of 0.37 degrees, but I ran it again right after and this time there is a difference of 76.04 degrees.
Anybody experienced anything like this? I am 99% sure the solder joints are good (I do occasionally repair pcb:s so I have got a quality soldering Iron and know how to use it)
I just can´t seem to figure it out. Is the black wire bad? or is the magnet bad? Could it be weakened by heat? Bad board?
I have another salvaged ETM that I will put in to see if I can get it running while I repair the contactless one.

I should have answered this 9 months ago but here goes: Sensor 1 is the 5 pin side of the throttle.

Sometimes the board receives input from 2 very good contact sensors (or a Sacer Hall sensor) yet fails to process one of the signals into a definable throttle angle. In this case it will report 108 degrees on the faulty side. This is view-able in Vida under throttle Position sensor 1 and throttle position sensor 2 in ECM-Parameters.

Many throttles have a failing driver on the processing board that is fine when cold and after a few minutes shuts down. It will often output both sensors fine for a few minutes and then suddenly shut down output from one of the sensors. It will then give either a ECM-9150 or ECM-9160 code.

All the more reason the Sacer sensor repair is becoming almost useless as the throttles age and other problems in them surface. Best to check the throttle angles both at cold and after 10-15 minutes of engine running with Vida to ensure that the throttle is processing both TP 1 and 2 sensors. A generic scanner won't show both TPS positions.
