OBDII Emissions Test-Texas

[Eric Waterman]

The '94 and up G20 is OBD2.  My wife's 97 SE-R has a '94 G20 ECU.

It seems like Tennessee is doing the same thing with testing, but only at
some stations.  I took my car last month to get tested. When I first pulled
in ( I was the only car there), one of the guys was guessing '96.  At first
I thought he was a Nissan fan. Then he asked me to turn the car off and step
out. I had no idea why.  He looked under the dash and pluged into the
generic port, not the Consult one.  They never looked under the car, or went
near the back.  That was until the first guy started the car.  The Courtest
muffler inside a garage is LOUD.  The other guy walked around back, and was
looking at the muffler and was asking me a few questions about it.  I passed
inspection, and the print out they gave me just said OBD pass.  It didn't
have any readings on it.  I was hoping to see if the S3 cams had increased
my emissions or not.  The strange thing was that we took my wife's car the
week before, but to a different station, and they did the usual inspection.
The back of the sheet they give back says this new test is for '96 and newer
cars.  This means that '94 and '95 G20s, and '95 Sentras/200SXs don't have
to get teh new inspection.
