ODB II reader for a 1995

I'm been wanting to get a ODB reader, but they all have warnings like this:

"Compatible with all OBD II-compliant vehicles from 1996 to the present"

Can I still use these readers on my 1995 Maxima?

I believe all US 4th gen maximas are ODB II, 95's port is on the pass. side by the ECU

any 95-99 maxima IS obd-ii the location as stated above is near the ecu, rather than being next to the fuse panel by your left knee.

As everyone stated, the 95+ Maxima IS OBDII. 95 owners get the best of both worlds here in Illinois, no emissions testing AND we have OBDII..its Niiiice

FYI: Not all 1995 maximas are OBDII but there are some. The models produced closer to 1996 have the OBDII connector installed but are considered OBDI.

Gain some knowledge before putting someone down who just might possibly have a valid point. Also if you notice, Creammotors is far from being a noob. He's been on since 2003. Now me..I'M a noob...to this website.

My pops is an instructor at the DC training center for Nissan, so I'd say he's a pretty knowledgeable guy when it comes to Nissans. According to him, my 1995 Maxima is OBDi. How do I know? It doesn't use the rear o2 sensor (post cat) for monitoring. Now what I mean by this is that the ecu still reads the post cat sensor, but will not throw a code when the sensor is bad. I just proved that theory 2 days ago with a consult, my rear o2 is shot, and it wasn't throwing a code. Nifty.

That doesn't mean it's 'OBD-I'. It may not be compliant to 100% of OBD-II specifications, but it does comply with most.

No. All A32s have an OBD-II DLC, as we've proved many a time.

Look for the plug by the glove box. If it's there get an OBD2 reader. I recommend one that gives you the description of the code on its LED screen. My 95 is obd2 readable, but according to NYC emissions test, it is not obd2. They have to put the sniffer in the tail pipe and run it thru several speeds and get the readings at those speeds, all while, a DMV camera records the test, and your car license plate. A real pain in the butt, cause the garage really wants to find something wrong, to compensate for their time.

holy crap guys.

ALL 4TH GENS ARE OBDII. The connector is down by the fuse box, near the driver's left knee (or if you're a tall bastrd, your shin )

That said, I'm pretty sure that 4th gens are not 100% compliant with OBDII, however, they read fine with an OBDII reader. I use a cheap eBay OBD2 to USB adapter and it works fine.

Except of course on the '95s...


96+ are fully OBD-II compliant as required by federal law. '95s (IME) are completely compliant in every aspect I've tried them, but some argue that they aren't fully.

Regardless, if you've got an OBD-II code reader and an A32 regardless of year, you can read the codes.

I didn't know that the 95s are on the wrong side.

I thought I read somewhere that 95s and 96s weren't fully compliant. But IMO, it doesn't really matter, as long as people can read the codes, that's all they'll really care about, lol.

Also, the baud rate (i think that's the term) of the ECUs sucks.
