i just got my 960 back from the dealership...they were suposed to run a scan to find out why she is spitting and sputtering under acceleration...i was told i need to replace my cam sensor and front O2 sensor befor they could continue with the diagnostic...right now i am just trying to get her back on the road and am sortof at a loss on what to do...i know that both sensors did not go bad at the same time and my 960 does not have a dlc conection or i would have a friend hook itup to his diagnostic system at the dealership he works for...the symptoms i have are spitting and sputtering under any type of acceleration unless she has not been started for a few days then she will run 30 or 40 miles with out a glitch, but after that she startes spitting and sputtering again...any advice, help or direction would be great...

thanks
dave

 

Maybe spark plugs or coils are bad or going bad.
Follow link to learn how to pull the codes.

It could be a bad O2 sensor.
The cam sensor usually either works or doesn't.

thanks!!!i will check as soon as i get home from work that may help with an array of problems that i have...

 

OK...i ran through the scan...

on block A i got 3-1-4 (camshaft position signal missing or defective) i know that needs to be replaced, and i got 1-3-1 (ignition RPM signal) i have no idea what that is telling me

on block B i got 1-2-2 (air temp sensor signal) i have no idea what this means either

both block A & B codes were pulled off port 2

can you please help me understand what codes 1-3-1 and 1-2-2 are telling me???

thanks,
Dave

 

The 131 code is most likely coming from the Cam sensor as well.
The 122 code Are you sure it came from B2? B2 is for the cruise control and I don't see a code listed for it.

 

i most likely plugged it up wrong on blockB considering block B did not have its own test lead or led...iused the test lead and led from blockA...theweb link that you gave me, does it have the other codes and definitions for the rest of the car???if not do you know where i can get them???

 

I only have them in a book But I think there is a list here on the forum I will try to find the link.

Here it is.

 

THANKS!!! now i can find out everything i need to know...now the question is do i want to know$$$ i will post what i find over the next couple of days...thanks for all your help!!!

 

No problem glad I could help.

 

OK, so i got my codes but i have run into a dilemma, i am missing connections (block A pins 5,6,7, and block B pin 1)

FAULTS

A-1) transmission
1-1-4 break in driving mode selector circuit (i can not reset this because i do have pin seven in block A)

A-2)fuel system
1-3-1 engine RPM sensor signal absent or faulty
3-1-4 camshaft sensor signal absent or faulty

A-3)ABS
1-1-1 no fault

A-5) transmission control,A-6) ignition system,A-7) combined instrument, has no pin

BLOCK B IS BEING TESTED WITH LEAD, LED, AND PUSH BUTTON FROM BLOCK A BECAUSE THERE IS NO TESTING TOOLS OTHER THAN PINS ON BLOCK B

B-1) climate control
no pin

B-2) cruise control
1-2-2

B-5) SRS
1-1-1

B-6) power seat
no read from pin

is there another way to reset the transmission and is there another way to get fault codes for the other systems, or are those systems to be done the old fashion way??? (trial and error)

 

It won't clear in A-1? If not the switch in the console for sport and economy might be bad.

The cam sensor might be bad. DId those clear?

I wouldnt worry about the cruise 122 I think that is a code that says the car has not reached 25 MPH.

 

no, it did not clear in A-1...is the procedure the same???...i am going to replace the cam sensor this weekend...i could not get any of the codes to clear but im not really concerned with it right now...i will work with it more when i have gotten her running properly again...

 

Yes it is the same with all the ports.

 

thanks for all the help...it turned out to be the cam sensor...after i got that done i had to replace the water pump so i did the timing belt, tensoner pully and idler pully...now it is on to the next problem...i am going to start a newthread on that thoughthanks again for all your help!!!!!!!!!!!!

 

my 96 960 did the same thing.... it was the intake manifold gasket
