Figure now is better than never. I bought a Volvo mid January to replace the Audi as I needed some transportation before The Great Escape. So the day before I left, the title came in the mail. No proof pics. I never got around to it…

Hank sitting inside can be proof, right?

My late grandma's neighbor had one of these, same color and wheels, but it was a wagon. Not so sure about the turbo part, though. I always thought it looked good.

The sedan version doesn't look much worse. Glad it served you!

5 cylinder turbo should be on every bucket list, I know it's on mine.

I’ve had one with turbo and two without, so that’s that bucket list checked.

And if you actually want measurable acceleration in one of these, at least with the four speed auto most of them had, the turbo is what you want. The naturally aspirated engines are mostly good for turning fuel into cabin heat.

It has a different sound and the gear change to second has neat “ch-duuuuuu” noise.

Sooooo, I figured out why I'm getting a P0130/P0135. The fekkin' 1st O2 sensor isn't even there!

I'm 99.99999% sure that the reason for this is because where the catalytic converter should be is a nice shiny piece of pipe. Somebody stole the original cat and ripped the O2 sensor wiring with it. Explains why this was cheap in American used car language. :)

*sigh*

So, after getting the O2 sensor in and the "replacement" connector for the vehicle side, the vehicle connector is too small for the O2 sensor to plug in to. No amount of practice will make these plugs connect. Sooooo, I go to a junkyard, places around here either don't have an 850 in the junkyard, or as one place told me "we take all that stuff out first and throw it away." No parts store in the area has it. They all stock or will need to order at 2.5 times what I paid for the connector online. Which as we know isn't correct. Once I bring up with these shops "well since you don't have something, do you have a generic 4 pin connector set so I can just splice in my own connector?" They all shake their heads and mutter "no." Ok jackasses, so I should just run a car without a working O2 sensor? fucking Christ.

O2 sensor on the left, supposed correct fit on the right.....

Before you ask, I called the local Volvo dealer and their own parts diagrams do not show O2 sensors and subsequent cabling. -_-

So I went to Amazon and got a could of generic 4 pin automotive connectors and I'll just use the wiring from this pigtail and crimp it into the factory stuff this weekend. I tried to go the correct route........

Call me crazy but that looks like it should fit, must just be the perspective. The pegs are correct relative to the pins but it's all just scaled up?

It's just a sensor, so at this point I would be using spade terminals and jumper wires, then wrapping the entire thing in heat shrink and/or tape. Or just cut the plugs off and use crimp terminals. Looks like you've got it in the right orientation.

Randomly changing plugs is a 100% Volvo move. My 740 has it's own wiring diagram in the Haynes manual because it's a 1989. I still haven't been able to acquire the correct heater blower motor resistor, or a blower motor with the correct plug because there are three variations of both...

The 850 was a complete reboot with a new platform and drivetrain. They’re nowhere near as difficult to deal with as a 240 or 740.

It is when I haven’t a clue what voltages i should see on the signal and sensor heater circuit.

But there’s only one rear brake caliper, not three different ones depending on which way the wind was blowing at the Torslanda plant that day.

As long as you don’t have an AWD unicorn, anyway.

This is true.

Currently finishing up the o2 sensor install. I found a diagram from a British website that describe the wiring colors that match what is on my 850. So fingers crossed this works. It will need a decently long drive to ensure the engine code doesn’t come. Hopefully!

SO!

First drive shows I didn’t quite get around the clamp tightened against the pipe all that well. So I got some exhaust sealer because I drilled the hole for the sensor too close to the pipe bend, so the clamp leaked some gases by. Once I let the sealer set for 2 hours, cleared the code for rich exhaust gases. Drove for 10 minutes and a new code appeared. Apparently the EGR isn’t opening like it should.

Ok.

Sooooooooooo.

Tuesday, I did the IT method and unplugged, replugged the EGR solenoid plug, cleared the code and have driven about 40-50 miles since I cleared the code. So far no CEL anymore. yay.
