The TPS (throttle position sensor) and the speed sensor are not directly connected on a 1999 Jeep Cherokee. However, they are both important sensors for the vehicle's engine and transmission control systems. The TPS is used to monitor the position of the throttle plate, which controls the amount of air that flows into the engine. The speed sensor is used to monitor the vehicle's speed, which is used by the transmission control system to shift gears.
If either of these sensors fails, it can cause the vehicle to run poorly or even stall. In some cases, a faulty TPS or speed sensor can also cause the Check Engine Light to illuminate. If you experience any problems with your vehicle's engine or transmission, it is important to have the vehicle diagnosed by a qualified mechanic to determine if either of these sensors is faulty.
