Hi all, I replaced the odometer gear on my volvo 850 and now my odometer, speedo, and turbo work and all the lights and the computer works fine, but my gas and temp gauge don't work. Did i damage the pins when I took the cluster apart and can this be fixed or are they dead to me. With the temp gauge...

i'm going to replace the coolant temp sensor, and can I get a used one from any 850, or does it have to be new?

Also, the turbo doesn't seem to engage any more, if I accelerate hard, the turbo never kicks in.

hey guys. So it can't, or likely isn't the maf because i replaced it with a new one 10 months ago, and i change the filter every time i change the oil, so I doubt that went again. So everything looked fine and the car was functioning great, except for the CEL or the o2 sensor. Driving home, i was sl...

so I checked all the parts of the coolant system and it seemed fine, and the car was running fine. I cleaned the throttle body and it seemed like I fixed it. Then, driving home today, I got a CEL, though the car still drove fine. Went to autozone and the code is po133, so should I replace the o2 sen...

That's the one, the coolant temp gauge. Also, I had the heat on this morning which was the first time It'd been on in months. There is no CEL on so could I have Autozone check for codes or would nothing come back?

yikes, i've clearly illustrated my lack of knowledge, haha. In the cluster with the turbo gauge and the gas gauge, the one to the left of the gas gauge, "oil pressure gauge"? That one dropped. I'm going to clean the throttle body when I get home.

Thanks for your help!

Hi. I've had an 850r for about a year now. The car has given me no trouble, except a month after I initially got it, the car started to stall out on the way to work if the engine rpms droped to 1500 or below. I made it home by constantly revving the engine and after looking it up on this site, deter...

I had the codes scanned at autozone and it came back with po103, with seems to be the code for failed MAF sensor? Do you guys think that's what is causing this issue, and if so, could i replace it myself?

I've had this 1996 volvo 850r for about a month and I love it. However, this morning, when I got into it and started it up, it started fine, but when I pressed down on the brake and shifted it into drive, it died. Tried again, and it worked fine, however the check engine light was on. On my lunch br...
