Where is the speed sensor located on a 1997 dodge ram 1500 truck?

The speed sensor on a 1997 Dodge Ram 1500 is located in the transmission. It's not in the differential like some vehicles. To be more precise, it's usually on the output shaft of the transmission, near where the driveshaft connects. You'll likely need to get underneath the truck to access it.

However, there are two speed sensors:

* Vehicle Speed Sensor (VSS): This is the primary speed sensor, used for the speedometer and other systems like cruise control and the transmission's shift points. This is the one most commonly referred to when people talk about the "speed sensor."

* Output Speed Sensor (OSS) / Transmission Speed Sensor: This sensor is also located in the transmission, often on the same housing as the VSS, and it specifically monitors the transmission's output speed. It's important for the transmission's operation and anti-lock braking system (ABS).

Without knowing the exact configuration of your 1997 Ram 1500's transmission (automatic or manual), it's impossible to give a perfectly precise location. A repair manual specific to your truck's year, model, and transmission type will be the most accurate source of information for pinpointing its location. You can find these manuals online or at auto parts stores.
