Hello and Welcome to Justanswer, My name is Steve and I am here to try and assist your with your question
it is Saab code for the cam sensor
p0340 is a generic code that all manufacture have to have code 28 is Saab unic code for the same concern
it is Saab version called electronic on board diagnostic versus obd2
Hi Steve - yeah, gathered it was Saab specific (looked at and read many blogs) - I have replaced the cam sensor, engine still will not start, the code narative states "Camshaft Position Sensor Circuit Range/Performance" - which I understand to be a P0341 code!!
the problem is it does not start and if you have no spark then the crank sensor is bad
Steve - its a diesel, so no spark at any time!!!
sorry did not relize it thought it was a gas
what is the fuel pressure?
if you suspect a bac cam sensor and you replaced it then the wiring or the computer is bad
Camshaft Position Sensor Circuit Range/Performance is usally a wiring problem
a cam sensor will cause a no start on a diesel
I believe I answer your original question. "Seeing a P0340-28 code - does anyone know what the 28 denotes please??"
"Be interested if anyone knows what the 28 suffix to the P0340 code indicates! Many thanks in advance"
need to move on please hit the green accept button so I may get credit thanks.
Have checked the wiring as far as I can (removed the main harnesses to the ECU, checked over completely and could find no problem) - again reading the blogs (Saab and GM) many folk have suggested the wiring, so had checked it out as far as I can!

Steve - I was expecting a resolve for my problem, rather than just a "you need a mechanic" response - I expected that in logging my problem here I would recieve input from a mechanic who had experience in this type of problem - I am not prepared to pay nearly £30 for the input you have provided so far, it hasn't helped me at all!!!
that was not the question
you wanted a code defination not a diag
you should have stated that in the question
some problems are to difficult to diag over the internet
unfortunately my ohm meter and my body cannot go through hyperspace and diag the concern for you and this level of concern you need a body to diag it
