The code could indicate the sensor has failed, a wiring issue, or a control module issue.
Here is what I suggest. First, check the input speed sensor. The first 4 pics below are the directions for testing the sensor and wiring at the sensor. Do this first.
The next six are the procedures for testing the wiring, power supply, and ground.
As far as your question is concerned, yes, they are both located there and look alike. If you look at the very last pic below, I circled the two. ISS is the input speed sensor and OSS is the output speed sensor.
Let me know if this helps.
See pics below.
