Big dissappiontment, need help plz.

7 posts in this topic

I plugged in my scan tool today and was surprised how many codes I got. I have a total of 18 codes with some of them repeated more than once. Any tips or suggestions before I start wrenching on it this weekend? I want to take the right approach to this and some help would be very much appreciated. I'm going to start with checking my wires for any mix up but everything was pretty much fool proof. I had everything marked and numbered and the only thing I had to wire up was the o2 sensors. All the other connections had harnesses so it just clicked together. 

p0303- #3 misfire

p0015- exhaust cam shaft over retarded

p0351- ignition coil a primary secondary circuit

p0234- turbo charger overboost condition

p0236- turbo charger boost sensor A circuit

p0108- manifold absolute pressure bar sensor high input

p0102- mass or volume air flow low input

p0505- idle air control system

p0014- exhaust camshaft position timing over retarded bank 1

p0303- cylinder 3 misfire detected

p0351- ignition coil a primary secondary circuit

p0234- turbo overboost condition

p0236- turbo overboost sensor A circuit

p0108- manifold absolute pressure high sensor high input

p0102- mass or volume air fow circuit low input

p0505- idle air control system

p0014- exhaust camshaft position over advanced

Have you still got the codes if you clear them and read them again without starting the engine?

 

Is your cam timing correct and are you using the correct head for the management system?

 

You can swap the coils and plugs over on number 3 and 4 cylinder and see if the misfire moves to cylinder 4. 

 

Vida or a VCT2000 would be a big help for you.

Thanks for the quick response Tim. I did a reset with the ecu twice, I left the battery unplugged overnight a couple times between checking codes to clear the ecu. My next attempt is using the scan tool to reset the codes as well but dought that will work.

-I think the cam timing should be spot on, I lined up the crankshaft single tooth mark on the gear and got it lined up the the mark on the block. I cross referenced by watching some DIY videos and manuals. I did a full phase one motor swap to a phase two car. So a phase one head(motor in my case) won't work with phase two software? I called numerous stealerships and they said the swap would work no problem. 

-I will swap the coils and see if that does anything like you said.

-I called a guy I got a referral from and he believes it's a timing issue. Price quote of $400 USD to look over my work and re-time my cams and look at ecu codes with a scanner that does the same thing as vida he said. The craftsman 20890 scanner I have works great but doesn't clear all  the codes and has generic codes sometimes making it difficult to narrow things down. Its a legit volvo specialist shop and think I may take the $400 hit at this point, volvo wants double the price.

Hang on, so you have a car that should have VVT and 2 boost pressure sensors and you now don't have these and you have fault codes for them? If you have the orignial ECU or at least one for a car that should have VVT and two boost pressure sensors you have a problem!

Yes, the engine has vvt on the exhaust and I'm running two oem map sensors.

I thought you had a Phase 1 motor?

 

I'd double check your cam timing, not the cam pulley timing but the cam timing.

The motor is a 2000 s40 us edition. The two pior 2000 s40s I used to own had vvt on the exhaust and one map sensor on the intake manifold. My 2003 has two, one on the cold side of the intercooler and one on the intake manifold.

I will give the cam timing another shot. I'm going to use the data log feature as well on my scanner (first time using it) and see how that works. I'll try uploading the datalog info tomorrow night. I'm not giving up on the car, not after 5 months of work on it and still needs M56 swap next year. 😀
