Where is my input speed sensor located

Good evening,

I attached a picture for you to view.

Why are you replacing the sensor? Do you have a code for this sensor?

I was told it is most likely the speed sensors and since there's input, output, and vehicle speed sensor they just ordered this part for me and said this was it pretty much lol. AutoZone. I probably am not even replacing the right part. I just recently had to take it to Mitsubishi and have them replace two wheel speed sensors due to ABS issue.

Got it.

What is the code number?

Roy

No clue. Sorry, I don't think anyone used the machine on it.

That would have been the first place to start to see where the area of failure is located.

The input speed sensor is a guess and I doubt it is the issue.

You can have a parts store check for codes for free.

I went to both parts stores, since my check engine light isn't on, they said the machine won't find any codes.

Jesus! Haha. Okay, so I asked AutoZone why I got the input sensor when in pretty sure I needed the output. They claim there is no output on my year Mitsubishi, that when they search it, the only thing that comes up is the input. Ugh. This car is a pain in my A**.

Okay, first, taking advice from a parts salesman is never a good idea. You need a technician opinion, not a parts guy.

The speedometer is controlled by the vehicle speed sensor not the input and output speed sensor.

Do you have a scan tool to see if there is a signal to the PCM?

You do have an output speed sensor. I attached a picture for you to view.

The speedometer is acting very strange. It's different every time, sometimes it is 5 mph off or even 40 mph off. Sometimes when I stop at lights it still reads 5-30 mph, or when it is off it sits at 20-40 mph. All my other gauges and odometer still work fine. I was told it is a speed sensor on this site. My car only has input and output, I have called multiple auto parts stores, that's all that shows up other than wheel speed sensors.

Anyway, I bought and replaced the output speed sensor because I was told it sends speed to the cluster etc. Well, didn't work. $99.00 down the drain. The input shouldn't affect the speedometer I'm told, so should I just get a new "used" cluster?

Also.

I have flickering dome/headlights. My battery tests fine but it's also only four months old. My voltage shows 12.8 when off, when car running 13.5, and with all electrical stuff on it actually goes down to about 12.8-13.0... The auto store that did my test on their pricey machine claims that's fine, but I read if it was under 14.2 while running, then alternator needs replaced. Just need some help. Lol
