The RAM Code P2580 is a Turbocharger Speed Sensor Circuit Low. This error code is triggered when the Powertrain Control Module (PCM) detects an issue with the speed sensor of the turbocharger, which is comprised of a coil of wire and an iron core. The signal generated by the flat surface on the turbocharger shaft spinning past the speed sensor is interpreted by the PCM, and if it fails to pass two consecutive drive cycles, the Malfunction Indicator Lamp (MIL) is illuminated. This can lead to a power derate and the MIL will turn off when the diagnostic passes in four consecutive drive cycles. There are many potential causes for this issue, ranging from signal circuit shorts to ground, PCM grounds, and faulty components like the Inlet Air Pressure Sensor, Intake Manifold Pressure Sensor and Turbocharger Speed Sensor. In order to accurately diagnose and solve this problem, it is important to understand all the causes and solutions.

When RAM Code P2580 is triggered, it is essential to identify the cause of the issue in order to resolve it effectively. This error code indicates a problem with the Turbocharger Speed Sensor Circuit Low and can be caused by a number of components, such as the Turbo Speed Sensor Signal Circuit Shorted to the Turbo Speed Sensor Return Circuit, the Turbo Speed Signal Sensor Circuit Shorted to Ground, the Turbo Speed Sensor Signal Circuit Open/High Resistance, the Turbo Speed Sensor Return Circuit Open/High Resistance, the Fused B+ Circuit, the PCM Grounds, the Inlet Air Pressure Sensor, the Intake Manifold Pressure Sensor, and the Turbocharger Speed Sensor. To diagnose and solve this problem, it is necessary to understand the causes and corresponding solutions.
TURBO SPEED SENSOR SIGNAL CIRCUIT SHORTED TO THE TURBO SPEED SENSOR RETURN CIRCUIT
When the Turbo Speed Sensor Signal Circuit is shorted to the Turbo Speed Sensor Return Circuit, it is important to check the wiring and connections of the circuit and replace any damaged components. This will ensure that the circuit is functioning correctly, and the signal generated by the flat surface on the turbocharger shaft spinning past the speed sensor is properly interpreted by the PCM.
TURBO SPEED SIGNAL SENSOR CIRCUIT SHORTED TO GROUND
If the Turbo Speed Signal Sensor Circuit is shorted to ground, it is essential to inspect the wiring and connections of the circuit and replace any damaged components. This will ensure that the signal generated by the flat surface on the turbocharger shaft spinning past the speed sensor is accurately interpreted by the PCM.
TURBO SPEED SENSOR SIGNAL CIRCUIT OPEN/HIGH RESISTANCE
If the Turbo Speed Sensor Signal Circuit is open or has a high resistance, it is necessary to test the resistance of the circuit and replace any damaged components. This will ensure that the circuit is functioning correctly and the PCM can interpret the signal.
TURBO SPEED SENSOR RETURN CIRCUIT OPEN/HIGH RESISTANCE
When the Turbo Speed Sensor Return Circuit is open or has a high resistance, it is important to test the resistance of the circuit and replace any damaged components. This will ensure that the signal is accurately interpreted by the PCM.
FUSED B+ CIRCUIT
If the Fused B+ Circuit is defective, it is essential to check the fuse for the turbo speed sensor circuit and replace any damaged components. This will ensure that the circuit is functioning properly and the signal is interpreted by the PCM.
PCM GROUNDS
If the PCM Grounds are damaged, it is necessary to inspect the PCM grounds and replace any faulty components. This will ensure that the signal is accurately interpreted by the PCM.
INLET AIR PRESSURE SENSOR
If the Inlet Air Pressure Sensor is faulty, it is important to test the Inlet Air Pressure Sensor and replace any damaged components. This will ensure that the PCM can correctly interpret the signal.
INTAKE MANIFOLD PRESSURE SENSOR
If the Intake Manifold Pressure Sensor is defective, it is essential to test the Intake Manifold Pressure Sensor and replace any damaged components. This will ensure that the signal is accurately interpreted by the PCM.
TURBOCHARGER SPEED SENSOR
If the Turbocharger Speed Sensor is not functioning properly, it is necessary to test the Turbocharger Speed Sensor and replace any damaged components. This will ensure that the signal is interpreted by the PCM.
Conclusion
When RAM Code P2580 is triggered, it is essential to identify the cause of the issue in order to resolve it effectively. This error code indicates a problem with the Turbocharger Speed Sensor Circuit Low and can be caused by a number of components. By understanding the causes and their corresponding solutions, it is possible to accurately diagnose and solve the RAM Code P2580 issue.
