P1Aa2: Unveiling The Mystery Behind Your Car’s Battery Performance
The P1AA2 fault code indicates an over-temperature condition in the StarterGenerator Inverter Phase V. The Power Inverter Module (PIM) temperature 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 shorted low or high conditions. If the inverter phase V temperature sensor is shorted high, the P1AA2 fault code will be triggered.
FAQ
If you see the engine light on or the service engine soon warning light in your automobile, it could be due to the P1AA2 fault code. This code is 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 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 SGCM 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 P1AA2 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, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins to fix the issue.
Wrap Up
If your engine light is on, 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 the issue, visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
