Re: 1996 Saturn Fails NY Inspection

 Try some injector cleaner for a tank-full.
Replace plugs, wires. Check spark intensity (if it has a distributor - cap
and rotor)
Anything mechanically loose will look like a knock and retard the spark. I
had a loose A/C compressor that was triggering the knock sense. A worn
engine mount can do this too. Listen and feel closely for anything that
doesn't sound right. Check the torque on the knock sensor mount. This sets
the sensitivity.

No idea what causes the P0733 code
obd2 codes decipher P=powertrain, next number is 0 for generic codes and 1
for manufacturer specific codes. The shop manual should explain what code
P1406 is. Alldata had something that referenced the EGR valve.
96-T-31 JUN 96 Engine Controls - Revised DTC P1406 Diagnosis,
EGR
Good idea to pull the EGR and check that it is not stuck or otherwise
defective. A leaking EGR will cause a bad idle and possibly give your
problems.

They really check the trouble codes in NY?

I wonder why he passed in previous years, then. Not to be too cynical, but here in Hawaii when
that sort of thing happens we look for a different state inspector. ;-)­

Just started this year. Statewide, too...

Prior years, upstate NY didn't have any emissions, downstate didn't
ODBII check. Now, the OBDII code scan is a statewide thing.

Repair shops upstate just LOVED having to buy the $$$$ state mandated
code scanner machine / state computer hookup, just to check a couple of
cars a month. I'm sure motorists love it too...

They really check the trouble codes in NY?

Started 4/1 of this year for any vehicle '96 and newer. Older vehicles
still have to have emisions checked on the dyno as done previously (at least
downstate). Basicly, it's a pretty fool proof way for NY to inspect the
vehicle. In the past, you could shove the emmisions probe in teh tailpipe
of another car, or find other tricks to fool the emisions machine. Now,
they basiclly use the on board computer to check how your vehicle is
performing. You can't fool it because the onboard computer has the car
information (VIN, etc) and the inspector has to scan the bar code on the
registration sticker in the window. If they don't match, it fails. The
other thing is that the onboard computer keeps a list of trouble codes in a
que of some kind, so even if you've fixed the problem, you have to drive the
car for about 30 minutes in normal traffic before it'll clear out. In
addition, if the mechanic resets the onboard computer, you again have to
drive it for about 30 minutes before it'll start "recording" anything. If
you try to inspect the car before the 30 minutes, it'll come up as a
failure. Techinially, on a good car, Inspection time goes a lot quicker.
They just do the safety, and plug in the computer and off you go. But if
you have a code issue, they could be chasing the problem around for hours or
days. My suggestion for all NY'ers is to get your car inspected at least
3-4 weeks before it's due if it's a older car and if you've have the service
light come on at all.>

 Regarding the 0733 code and incorrect gear ratio, I am guessing there may be
a defective or failed transmission solenoid so the transmission is not
shifting to the proper gear as the computer would like. I posted a
procedure for measuring the solenoid resistance about a month back. It only
requires removal of the connector which is held on by a 7mm? bolt and a
basic ohm meter. It would take no more than 5 minutes to check these
resistances. there are 5 solenoids and 10 pins in the connector. Each
solenoid uses adjacent pins and all should measure 4-6 ohms when cold. If
you find one, like I did with a higher or lower resistance (mine was 1600
ohms) it has opened or shorted so needs to be replaced. The procedure was
not too difficult and parts cost was about $80 for the solenoid and trans
cover gasket. I'd suggest they do the diagnostic to see if a solenoid is
not working so would leave the trans in the wrong gear...given the lack of
other symptoms, it is likely this is the overdrive (4th) gear.

Bob

Good luck!
