2002 saab 2.2d engine error code p1222

this isn't a simple repair job, the knock sensor must be replace, I would also make sure that this IS the knock sensor that is the issue here otherwise if you replace and clear the codes the same issue will appear again, sometimes the engine computer will throw a code that is correct but misinterpreted which I believe might be your case,If you have a knock sensor code on any Nissan (in my experience) replacing the knock sensor will not fix it. The knock sensor detects unwanted engine vibrations, such as miss fires. So if you have a knock sensor code first check your spark plugs, are they in proper condition? (if not replace them). Next quest vans are known for clogging fuel injectors so i would recommend running a can of sea foam injector cleaner.

I HAVE 2006 SAAB 93, 2.0 ENGINE 4 CYLINDER. I HAS AN INTERNAL ECU ERROR, CANT TURN ON

spark plug misfire, check your plugs and wires for burn marks or fowled...

The simple one, you have a rear light blown. As for the check the engine light "you would need to get the code checked, that any Saab dealer can get by plugging a device into your car, and from there the problem will be narrowed down" sorry I cant be more specific but that light can come on for a multitude of reasons. :-(

Well, these are 3 issues and for the A/C have to check the coolant pressure, engine knock is not good and will have to have it checked out by someone who knows Saabs.

No I don't think so, knock sensor only work under engine load, when sensor picks up a ping or knocking, it will adjust timing, o2 sensor could be bad, and will save you fuel mileage, but a miss will also give you an o2 sensor code, running rich, have him check for cylinder miss first.

if you correct the miss the trans will shift correctly, the engine miss set a trouble code, that will ID the cylinder that is missing, have the trouble codes tested

Check wiring if all good than bad sensor
