Hello all,

I am trying to fix my 1994 850 Volvo Turbo, and have just this afternoon pulled the codes. I was wondering if anyone could give me some info about these errors. While looking over them, do you see any errors that piggy-back off the others? Perhaps replacing one part could knock out several errors?

Also, I'm surprised to find that I received no errors regarding my transmission. I say this because while shifting into different gears, I encounter startling jumps that I thought were foreshadowing a transmission issue. For example, when I am in park, I have to have my foot on the break for about 3-4 seconds, with the car on (of course), before I bring it into reverse. If I don't, the car does a scary jerking movement. The same will happen when I go into drive from reverse - I need to sit there for about 3-4 seconds with no movement, then push it into the new gear. Thoughts?

This is my first Volvo so I may be experiencing normal characteristics for the car, just not realizing it. While it feels great to own this European machinery outright, fixing it is a daunting task.

Sorry - last question. Do any of these errors scream, "FIX ME OR I'M GONNA DIE TOMORROW!"?? I don't want to kill this sweet little car.

at a guess the cruise control may get its speed signal from the same source as the abs, as that self tests at 22mph, so that may be from the right or left wheel sensor. 444 on abs is when it loses electrical power, so may have been caused by the engine dying.
I'm also wondering if the transmission get a signal when the wheels are stopped from the abs sensors, this might explain the delay from forward to reverse, while it looks for a stopped signal and waits 3-4 secs for a timeout.

Grendel,

Thank you so much for your reply. I am hopeful that this code does depend on the need to replace the ABS sensors. I have looked into replacing them - they aren't the most expensive item I will be needing, but it is still a hard pill to swallow. I'm enjoying fixing this car up and I hope to replace these bigger items soon.

Again, thank you for your help,
Jenn

ABs sensors, if you unplug the connector you can check the resistance, if you dont get a circuit the sensor is dead, if you rotate the wheel the resistance will pulse. you dont have to take them out to check them, the front ones unplug at the sensor, the rear ones have a common plug near the access panel for the fueltank, thewiring back to the abs unit can be checked once the sensors have been plugged back in, at the plug end by the abs unit.
