P1Aa0: Decoding The Mysterious Hybrid/Ev Battery System Fault
The P1AA0 fault code is related to the StarterGenerator Inverter Phase V Temperature Sensor Circuit.
This fault code is triggered when the inverter phase V temperature sensor circuit has low voltage.
The Power Inverter Module (PIM) temperature 1 and 2 sensors are used for overheat protection. The thermistors are located on the control board, near the phase U or V power MOSFET.
The StarterGenerator Control Module (SGCM) monitors the inverter temperature sensor for detecting if the inverter phase U or V temperature sensor is shorted low or high.
FAQ
If you see the engine light on or the service engine soon warning light in your automobile, it could be due to the P1AA0 fault code. This code is usually 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 this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
If you’re experiencing the P1AA0 fault code, indicated by the Engine Light or Service Engine Soon Warning Light being ON, it could be due to a faulty Starter/Generator Control Module (SGCM), an open or shorted SGCM harness, or a poor electrical connection in the SGCM circuit. To fix this issue, visually inspect the related wiring harness and connectors for any damaged components, broken, bent, pushed out, or corroded connector’s pins. Check for the possible causes listed above to ensure a proper fix.
Ignoring the P1AA0 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 inspect the related wiring harness and connectors and check for damaged components to avoid further damage.
Wrap Up
If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to a faulty StarterGenerator Control Module (SGCM), an open or shorted SGCM harness, or a poor electrical connection in the SGCM circuit.
To fix it, visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
