Because the initial thread began as a general inquiry about sparkplugs and
then kind of moved around, I thought it best to start anew....

re: 2000 C70
Car running rough, thought was it needed new plugs...
Bought a Equus 3030 and here are the results - codes off the unit,
description off of Volvoforums.org:

P0302 Cylinder 2 Misfire detected
P0352 Ignition Coil B Primary/Secondary Circuit Malfunction
P1550 PSPS Out Of Self Test Range

The plot thickens?

My first guess would be a bad coil, that could easily cause the first
two errors and the rough running. I'm not sure what a PSPS is so I can't
say whether that supports my hypothesis.
 
And I was hoping it was just a bad batch of gas....

Thanks James.. let's watch for some other replies...
 
cylinder 2 is misfiring & it's coil is malfunctioning. that seems easy
replace one lousy coil out of five (ok, you can play w/ all the
connections first.)

power steering pump sensor. check the power steering fluid. then round
up the usual suspects
 
Ok, here we go, more info....

The Equus came with software, so after reading the codes and matching them
up on a volvo site, I decided to install the software...
Great software! It asked for VIN number, etc, and then read the unit for
stored codes....

0302 was confirmed as misfired cyinder 2, 0352 came up under stored codes,
Ignition coil B Priamery/ Secondary Circuit...

Also under stored codes, 1550.. with a different description... ABS wheel
speed sensor malfunction... this one makes sense, about a week or 2 ago, the
ABS light went on...

I'd like to see how much of these I can repair myself.. I do want to replace
the spark plugs, fine.. that coil, any insight on this? I will google
around to see what I can learn about it.. I am handy, but since cars went
computer I backed off.. with the r/depression going on, I need to get down
and get dirty.. which is fine...

Thank you for your help.. btw, I bought the Innova Equus 3030 at
Walmart.com - $44 delivered.. I am amazed with what it came up with and that
it spits out a report on the pc... I haven't been this excited since I
changed plugs on my 64 Chevy II!

Wheel speed sensor errors are often caused by a buildup of crud on the
sensor. Normally this is accessible after removing the brake rotor of
the offending wheel. Does this car use a coil on plug arrangement, or
does it have a distributor?

I had a bad coil I think it was 40$ at autozone and a 5 minute
install, it was the same as original and the dealer wanted 225, now it
runs fine

To replace the plugs you have to remove the coils from the top of the
cylinder head you will need either a 10mm socket or an 8mm socket to
remove the bolts that hold down the coils also mark each coil IE
1,2,3,4,5 so there is no placing the coil back in the wrong cylinder
seen it happen very often both on the outside & the inside

thanks..
Volvo I assume?

I have found inx on how to do it so betweent new plugs and the coil, I s/b
able to get it done on my own.. of course, with the help of my new OBDII-
and everyone's help here.. you, Richard, James... thank you all!
 
Cannot answer.. the manual mentions distributor and coil...

Can someone answer this: I would like to clear the error codes and move
swap the coil from cylinder 2 to another, to see if it's the plug or the
coil.. can someone advise how to do this, I have searched online.. no luck
yet...
thanks!
 
I found some great videos on YouTube....

switched coil 1 and 2, and cleared the error codes...

Now I will know one of 2 things.. A- bad coil, B-bad plug... C- since there
are no codes - yet - poor connection!

If the coils are connected directly to the plugs then you have
coil-on-plug distributorless ignition. Later Volvos used this, but I'm
not certain when the change took place.
 
Hi, James.. yes, that's what I have.. found some excellent videos on
YouTube.. it is very simple, very simple!
