P1A9B: Understanding The Hybrid/Ev Battery Temperature Sensor Circuit
The P1A9B fault code is related to the StarterGenerator Inverter Phase U Temperature Sensor.
This sensor is responsible for monitoring the temperature of the Power Inverter Module (PIM). The SGCM uses this sensor to detect any failure in the inverter temperature sensor circuit. The thermistor is located on the control board, near the phase W power MOSFET.
FAQ
If you’re experiencing the P1A9B fault code in your automobile, you may notice that the engine light is on. This code is often caused by a faulty Starter/Generator Control Module (SGCM), an open or shorted SGCM harness, or a poor electrical connection in the SGCM circuit. To fix the issue, it’s important to visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.
If the engine light is on due to a faulty Starter/Generator Control Module (SGCM), it is important to visually inspect the related wiring harness and connectors. Check for any damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This could be caused by an open or shorted harness or a poor electrical connection in the SGCM circuit. To fix the issue, check the possible causes listed above and address any issues found during the visual inspection.
Ignoring the P1A9B fault code in an automobile, which indicates a faulty Starter/Generator Control Module (SGCM), can lead to serious consequences. The engine light will remain on, and the vehicle may not start or may stall while driving. It is crucial to address the issue immediately by visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector’s pins.
