Hey everyone,

I have a little problem with my 1996 850 turbo, Ive searched and read about 10 posts that were close but im confused.

Ill start by saying Ive had this car since new and this motor has 390,000 and is still running strong, just minor issues.
I have broken down the motor before and have rebuilt 2 other 850 motors and have a short block sitting in wait for this one when it finally goes.

but here is my issue.
I had to replace the bottom crankcase hose on the pcv again because I was leaking oil from there again...
I replaced the hose... put everything back together... dropped in my battery... turned the key and it just cranks. Orange arrow flashing, econ/sport switch flashing. with P0120(TPS)
I have fuel flow, spark, and 165+/- 2 or3 compression across the board.

I cleared P0120 They stopped flashing. Cranked.... Nothing still.
Arrow and econ switch flashed again.

The car ran fine aside from the oil leak before,
I had to have screwed something up.... but im at a loss and I need some ideas...

has any one experienced this?

Thanks for the advice in advance

 

you must have missed plugging something back in. if you're getting a TPS code, check the throttle position sensor plug.

 

Im going to get a new tps right now just in case something did happen to it.. but ill go thru it and post what I find..

Also it is cranking weird... can you upload a sound file here?

 

Use your remote opener or key to open and close the car five or six times then get in the car and try to start it.

 

Well, after the new tps.... NO change.
BUT........... I am running again (smoking horribly form all the fuel that was loaded into the cylinders).

I found out my problem(s), There is a small bracket that holds the pcv lines down. My dumb A** had that bracket in-between the manifold and the block, not on top of the manifold like it was supposed to go. Also I found that the leads to my main relay were all corroded and green, I pulled them and cleaned them...

Thank you guys for the help, thank you so much..

 

that's a common mistake many volvo owners have made (except me) lol. don't feel so bad...
