P1551 Fault Code: Understanding The Description And Troubleshooting Steps
The P1551 fault code refers to the Battery Current Sensor Circuit Low Input.
This code is related to the power generation voltage variable control system in your automobile. The purpose of this system is to reduce fuel consumption by decreasing the engine load caused by the generator’s power generation.
To monitor the charging and discharging current of the battery, a battery current sensor is installed on the negative terminal of the battery cable. The sensor provides a signal to the Engine Control Module (ECM), which determines whether or not the power generation voltage variable control should be activated.
When the power generation voltage variable control is engaged, the ECM calculates the target power generation voltage based on the sensor signal. The ECM then sends this calculated value as the power generation command to the Intelligent Power Distribution Module Engine Room (IPDM ER). If the ECM detects a low input from the battery current sensor circuit, it will trigger the P1551 fault code.
This indicates a potential issue with the battery current sensor or its circuit. It is important to have this issue diagnosed and repaired to ensure proper functioning of the power generation voltage variable control system in your automobile.
FAQ
If you’re seeing the Engine Light or Service Engine Soon Warning Light and have fault code P1551, there are a few possible causes to consider. One is a faulty Battery Current Sensor, while another could be an open or shorted harness for the sensor.
