Vida says that any voltage fluctuation detected by the ETM (caused by a loose connection or broken or shorting wire in the Control Area Network(CAN)) will cause the ETM to signal the ECM to go into limp mode even though the fault might not be with the ETM or the ECM. I'm still working on locating my...

Neither! BUT I just looked it up. What is the cheapest way in? Can it do a lot? I'll research tommorrow but if you could share your wisdom I would be very appreciative. My vehicle is a 2001 V70XC AWD with 217,000 mi so I don't need the latest model. I'm finding out that I have hardly kept pace with ...

MAF is New. I do not understand Vida Dice.

I found the original voltage (1.478V) and adjusted the Sacer to (1.477Volts) Closed up and put it all back together. Erased code; but it came back PO121 still in limp mode. I am still open to any and all suggestions. Thanks!

I properly disconnected Pin #2 and soldered black wire from Sacer to same. So, I am to remove the ETM to the bench; open the Aluminum cover; Attach (12V) to green+ and Brown- at the plug and take readings from 1&3 and 2&4. Desired result is equal readings. I saw somewhere that the input volt...

I have similar symptoms, but I get a PO121 Code; Throttle/pedal Position sensor/switch"A" circuit range/performance problem. I got a Sacer TPS sensor cap after limping home, and installed it very carefully. Erased the codes, started up, same result, limp mode, 2K rpm max, PO121. Are there ...
