Today I measured the TPS on the pins that connect to the transmission computer (pin 20 on part B of the connector). It seems absolutely fine, 0.55v to 4.2v, and it increases very smooth with the throttle. Matches the live data from ECU. Measured ground, seems fine. From this I conclude the TPS is wo...

Problem seems solved. New used TCU solved it.

For the windshield bottom, you mean where you clip the plastic tray into the glass? I destroyed mine, there is a replacement available from skandix/volvo. It was a different part but fitment was better than with the old one. don't have the pn right now. For the rubber seal on the roof racks I would ...

My '95 has both sips and passenger bag, (but no obd plug). Agreeing with Clemens on that one.

Hey, welcome to another Volvo enthusiast. Your R looks very nice. I'm thinking of going the standalone ECU way anyways I would very much like to hear of your experience to make it work if you do it. For now I will leave my car as is (I can still run the stock ecu for 'MOT" or one with tune), bu...

I am sure the ECT is the same on all these engines Regarding o2 sensor I would not worry about Hella, they are also an OEM and usually high quality. No idea if they produce their own or rebrand someone elses, but It should be good quality. I guess you could disconnect the O2 sensor to test, for star...

I only ever see these wires going into harnesses, never dug into these. But seems like they use a common sensor ground. Looked up ecu pin A18, says "Signal ground sensor (measure with neg. batt.)" have you measured resistance - sensor wire ground pin on sensor side to ground? - sensor wire...

I think that is the best pic I have, maybe someone else has some more info on the connectors. Note its from a me4.4, but shouldn't matter for numbering.

I know an old thread. But since I have a wiper motor open I thought I'd add a bit to it. Removed the wipers from my car way back since they did not work. Now I'm looking into fixing them, not because I'm a masochist :D , but If I ever want to look into registering it as an oldtimer it probably needs...

Tips from my side: Always record your fuel consumption. I know it is some work, but it pays off. Note displayed values can be incorrect, I always note distance and fuel consumed. If you are using excessive fuel then it is not running right. I was able to catch and diagnose some problems early becaus...
