Default code p1312

I have a 2003 9-5 linear, the check engine light has been coming on intermittently. The last time it was on I took it to a local mechanic and he hooked it up to his diagnostic computer and it gave him a code p1312. He's supposed to be getting back to me with what the problem is....Has anyone out there had this problem??? Is this something I can fix myself? I just had 900.00 dollars in work done on the car fixing oil leaks....AAArgh! Thanks!!!

Any idea where I can buy one? I suppose it would also be nice to have a service manual for the car... Know where to pick one of those up? Thanks

What other names might an exhaust temperature sensor be called?

I can't find that part anywhere online. Oxygen sensors fore and aft are the only sensors I can find in the exhaust system.

boostpowered, are you sure it's an EGT probe code? I have no means to check since I don't have a 9-5 WIS Installed, but IIRC most of them don't have EGT probes. The code could be coming back as something generic if you're referencing a regular OBD2 collection. Saab has used a few obscure codes for other things...


edit: crosschecking with other resources this could be a code for missfire in cylinders 1 & 2 which could be either a faulty ignition cassette or fauled plugs.

I also had this code and found on another forum that it is either your spark plugs or direct ignition cassette (DIC). I changed my plugs first since it was cheaper but still go the code after resetting it. Then I bought a new DIC at the dealership for $258 plus tax came out to $277. Reset my code and has not come back yet.
