HELP! New Speed Sensor after P0500 but Cluster Not Working

[pavan87]

I got a P0500 code last week so I replaced the speed sensor. I was having problems where the entire gauge cluster would freeze at the speed I'm going or it would all drop down to 0. I didn't replace the white wire that connects the actual speed sensor to the wiring harness since I couldn't disconnect the wiring harness connector from the white wire connector. I cleared the code and drove 100 miles or so and the light came back on. Even when the SES light was off, the gauge cluster would still get stuck.

After the SES came back on, I thought it might be the white wire connecting the speed sensor to the wiring harness so I went about replacing it. The two connectors were still stuck together and in the process of trying to separate them, the two wires (green and orange) from the wiring harness which go into the connector separated from the connector (all on the wiring harness side). I went to the junk yard and cut out another connector and spliced it into my wiring harness. I used connectors that you crimp and heat shrink to connect the two ends together. I haven’t driven very far yet, but the SES light is still on and it seems that the transmission is not shifting where it used to. It's an AT and go through all the gears but the shifts don't seem to be at the optimal moment. (The shifting may just be in my head since I think there is a problem.)

What is the easiest way to check to see if my splice is good? All of the wires are in there tightly especially after the heatshrinking, but it seems that it could still be a problem. Is there another way to solve the connector issue without splicing it in? If the splice is actually good, what steps should I take next to solve the problem? Should the SES clear itself if the problem is fixed or should I pull the battery to reset it? Could there be another problem other than the speed sensor that is causing the gauge cluster issue? Thanks in advance for any help.

What year is this for?

Sorry, I forgot to mention that. It's for a 1999 Infiniti I30. Thanks for reminding me.
