Make sure the fuse for the diagnostic connector is ok, look in the owners manual for it's location, it may be listed with other items so read the fuse descriptions for each fuse carefully.

Why can't I pass smog check engine light won't come on

The smog check requires a visual inspection of your check engine light. It has to come on for a bulb check at startup to make sure it's working. But, the light must go out after starting the engine(it cannot stay on after the engine starts during a smog check). If the check engine light fails either of these two tests, the vehicle will fail the smog check inspection.
You need to have the cause of your inoperative check engine light diagnosed and repaired.

Passing smog

code p 1340 refers to crank position sensor and camshaft position sensor signals out of sequence
the results of the pretest smog test at 2400 rpm suggest that the cam advance solenoid or system is failing
that will alter the sequence of the signals resulting in the code and failing of the smog test
as to answer you question , I am not convinced at this point but I consider the cam advance system to be at fault and would be testing in that area

Passing smog

I doubt it as you have stated that it shows a calibration fault . This will be from the variable valve timing assembly on the cam shaft/s that is altering the valve timing. The timing chain may be faulty but you should be hearing it to be that bad.

MIL/Check Engine Light will not come on during start up to pass smog 2000 Ford Mustang

There should be a 10amp fuse in the fuse box for the instrument panel that powers the light. The light is grounded by the computer.
Have you checked the fuses in the passenger compartment ?

Prerunner wont pass smog due to engine service light

Not positive on this so consider only. The o2 sensor is what actually tells everything else what is going on with emmission and everything else adjusts to what info it relays. The o2 is also subjected to extreme temps and cooling cycles. So, instead of spending money on no answer diagnostism give replacement of o3 sensor so consideratio. If you choose to replace, wd40 and let exhaust cool down. Good Luck.

Jetta failing smog due to non communication with OBD - Suggestions?

the no data error can be contributed to a bad interface cable or the scaqn tool was configured wrong and therfore could not connect to the ecm. I would recommend having a scan done again by a certiefied volkswagon tech chances are the mechanics used the wrong adapter cable or reader card. your smog problem could be that your evap canister is clogged therfore gives a bad reading.unfortunately you have to have a scan done but try an independant small shop that delas exclusively with foreign cars such as porche andd mercedez. the will have the correct scan tool and will be much cheaper than a dealership. your cost should be no more than 50 dollars US ... please rate this. thanks
