P1574 Fault Code: Understanding The Description And Troubleshooting Steps
The P1574 fault code refers to a problem with the ASCD Vehicle Speed Sensor.
The Engine Control Module (ECM) receives two vehicle speed sensor signals through the Communication Area Network (CAN) communication line. One signal is sent from the combination meter, and the other is from the TCM (Transmission Control Module). These signals are crucial for the ECM to control the Automatic Speed Control Module (ASCD).
When the P1574 code is triggered, it indicates that there is an issue with the ASCD Vehicle Speed Sensor. This can lead to problems with the ASCD system, affecting the vehicle’s ability to maintain a consistent speed. It is important to address this fault code promptly to ensure proper functioning of the ASCD system and to avoid any potential safety concerns.
A professional diagnostic scan and inspection of the ASCD Vehicle Speed Sensor will be necessary to determine the exact cause of the issue and to implement the appropriate fix.
FAQ
If you’re seeing the engine light or service engine soon warning light and the fault code P1574, there are a few possible causes to consider.
