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
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.
You will need to get it scanned and get the codes for the problem. If it failed the test due to emissions I would almost guarantee it will be your oxygen sensor or cat
it can be complicated to pass the smog test! check your gas cap. thats the most common reason for a fail! they will not tell you that. you can have it code read at any autozone or advance auto for free if your check engine lights on.[only] otherwise you're at the mercy of the only garage you trust. it may be a bad 02 sensor,you have 2 [cost around $75.00]each. it may be stopped up catalytac convertor,do you smell rotten eggs when driving or at idle? thats a sign of bad convertor. good luck and thank you for choosing fixya.com
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.
Try this:-
Theres a vaccum pipe tht fits on the brakes booster just under the mastercylinder probabely it may have popped out or the sensor could be faulty ....worth a try ;)
no is to high when I try to pass smog
