The P1AA1 automobile fault code indicates a problem with the StarterGenerator Control Module (SGCM), which can trigger the Engine Light ON or Service Engine Soon Warning Light. The cause of this issue could be a faulty SGCM, an open or shorted SGCM harness, or a poor electrical connection in the SGCM circuit.
It is important to address this issue promptly as it can lead to further damage to the vehicle. The repair difficulty is moderate, and the fix involves visually inspecting the wiring harness and connectors for any damage or corrosion. The fault code can be interpreted using an OBD-II scanner.
| Repair Importance Level | 10.0 (Out of 10) |
| Estimated Repair Time | Approximately 1.0 hour |
| Repair Difficulty Level | 10.0 (Out of 10) |

Most auto repair shops charge between $75 and $150 per hour. Therefore, the cost of fixing the P1AA1 fault code can range from $75 to $150. It is important to consider the repair time and the hourly rate when estimating the cost of fixing this fault code.
P1Aa1 Fault Code: Understanding The Hybrid Battery System
The P1AA1 fault code is related to the StarterGenerator Inverter Phase V Temperature Sensor Circuit. This fault code is triggered when the StarterGenerator Control Module (SGCM) detects a high voltage in the inverter phase V temperature sensor circuit.
The Power Inverter Module (PIM) temperature sensors are used for overheat protection and are located on the control board near the power MOSFET. The SGCM monitors the inverter temperature sensor to detect if it 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 P1AA1 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 P1AA1 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.
