1998 Nissan Altima GXE Front O2 Sensor

I purchased a Bosch universal O2 sensor because the OE one had melted.
After installing the replacement sensor the check engine light remains
on. I was told by Nissan that I connected the wires incorrectly. The
universal O2 sensor has 1 Black & 2 White wires. The car has 1
Red/Orange, 1 White & 1 Green wire w/ black strips. I have tried to
connect both white wires on the replacement O2 sensor, one at a time of
course, to the white wire connected to the car and nothing. I have
reviewed the wiring diargram in my Haynes Repair Manual as well as the
Universal O2 Sensor installation instructions and the wires do not
match up. The install guide sayes the wires should be 1 Black, 1 White
& 1 Gray and the Hanyes Manual says the cars wires should be
Green/Yellow, White, & Yellow.

I am at a lose as to which wire should be connected to another. Any
help??

I hope you didn't fry the ECM by connecting the wires incorrectly.

The 3 wires are 12 volts to the heater element

A signal wire to the ECM

and a ground

If any one of those were wired wrong chances are real good the ECM is
damaged

I'm curious as to how much you paid for that "universal" sensor, a factory
OEM part is way less than the ECM

Haynes Manual $25.00
OEM sensor $ 150.00
New ECM $ 600.00- $ 800.00

Screwing up your car because you didn't want to buy the OEM part that
fit's... PRICELESS

I hope I didn't fry it either, for your reason given. I didn't
purchase the OEM Sensor from my local Nissan Dealership because they
offered no warranty or guarantee. If it was defective or still did not
correct the situation, I was out that money and could not return the O2
Sensor. So...spending the $195 would have been pointless if it didn't
correct the issue. What I am going to do, however, is try to find
another 98 Nissan in the junk yard and take out the sensor along with
the original adaptor so that I can reconnect the car to a factory part.

Additionally, some time after posting my original message, I gave up on
fixing the sensor and brought my car to my local Nissan Dealership,
Inskip Nissan in Cranston RI, for them to correct. I dropped the car
off on Tuesday and as of Thursday; they still never touched the car.
The lack of service I received from this dealership was astounding and
I will never deal with them again. But back to my car's O2 sensor
issue...I found a few other message boards with other Altima owners
having the same issue. There were many postings indicating that the
ECU may need to be reset. I tried to remove the negative wire from the
battery terminal and that had no affect. One other posting mentioned a
small screw next to the accelerator that you would have to screw in
completely clockwise then counterclockwise...blah blah blah...

Never the less, there was no screw so I am short on solutions. I know
I have replied to this late, but if you know of any other way to reset
the ECU, I am willing to give it a shot.

An OBDII reader should be able to reset the computer. AutoZone should be
able to do it for you if you don't have one. Remember when you disconnect
the neg. battery cable you need to leave it disconnected for 5-10 minutes.
That has aways worked for me.

I had the neg connection disconnected for over 20 minutes. I went to
Auto Zone to have the check engine light turned off many times and it
keeps coming back. They have provided the error codes and after
researching the cause online, I have yet to come up with a solution.
Unfortunately I no longer have the codes.
