P1AAE Saturn Code - Phase Correlation Fault
Quick Answer
The Starter/Generator Control Module (SGCM) unit is an electronic device that works in conjunction with the electrical subsystem to efficiently perform DC/DC and DC/AC electrical energy conversion and support vehicle functions. Common causes include Faulty Starter/Generator Control Module (SGCM), Starter/Generator Control Module (SGCM) harness is open or shorted, Starter/Generator Control Module (SGCM) circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1AAE Saturn Description
This SGCM will have 2 functions. The first will be monitoring, where the DC voltage is transformed into 3-phase A/C power to the Starter Generator interface. In this case, energy flows from battery 36-volt to Phase 1, Phase 2, Phase 3. The second case will be generating, where the 3-phase A/C power is used to charge the 36 V battery pack. In this case, energy flows from Phase 1, Phase 2, Phase 3 to battery 36-volt. If the values of Starter Generator Speed and Starter Generator Torque are zero, then the Starter Generator Control will be disabled and the Starter Generator Inverter is not transferring or consuming any power.
3-Phase A/C Current will be defined as the current value of Phase 1. The current will be bidirectional, with positive representing discharging the batteries and negative representing charging the batteries.
What are the Possible Causes of the DTC P1AAE Saturn?
- Faulty Starter/Generator Control Module (SGCM)
- Starter/Generator Control Module (SGCM) harness is open or shorted
- Starter/Generator Control Module (SGCM) circuit poor electrical connection

The common symptoms include rough idling, engine misfires, loss of power, and potentially stalling.
2. What does the OBDII code P1AAE Saturn indicate?
The code indicates a Phase Correlation Fault, which means there is an issue with the timing correlation between the camshaft and crankshaft on the Saturn vehicle.
3. What are the possible causes of the Phase Correlation Fault code?
Possible causes include a faulty camshaft position sensor, crankshaft position sensor, timing belt or chain issues, engine timing problems, or wiring issues.
4. How can I diagnose the Phase Correlation Fault code on my Saturn?
Diagnosis typically involves using an OBDII scanner to retrieve the code, checking the camshaft and crankshaft sensors for proper operation, inspecting the timing belt or chain, and verifying engine timing.
5. Can I drive my Saturn with the P1AAE code present?
It is not recommended to drive the vehicle with the Phase Correlation Fault code present, as it can lead to further engine damage and potentially unsafe driving conditions.
6. How can I repair the Phase Correlation Fault on my Saturn?
Repair options may include replacing the camshaft or crankshaft position sensors, repairing or replacing the timing belt or chain, correcting engine timing issues, and ensuring proper wiring connections.
7. Is it safe to continue driving my Saturn if the check engine light is on due to the P1AAE code?
It is best to avoid driving the vehicle and address the underlying issue causing the Phase Correlation Fault to prevent further damage to the engine.
8. Can a DIY enthusiast fix the Phase Correlation Fault code on a Saturn?
While some experienced DIY enthusiasts may be able to diagnose and repair the issue themselves, it is recommended to consult a professional mechanic for accurate diagnosis and proper repair.
9. How much does it cost to repair the Phase Correlation Fault on a Saturn?
The cost of repair can vary depending on the underlying cause of the issue, parts needed for replacement, and labor costs. It is advisable to obtain quotes from reputable mechanics or repair shops.
10. Will resetting the OBDII code P1AAE on my Saturn make the issue go away?
Resetting the code may temporarily turn off the check engine light, but it will not fix the underlying problem causing the Phase Correlation Fault. It is crucial to address the root cause of the issue to prevent further complications.
