[SOLVED] P1A75 Code: Fixing Starter/Generator Control Module Temperature Sensor

If you see the engine light on or the service engine soon warning light, it could be due to a fault code P1A75. This code indicates a problem with the StarterGenerator Control Module (SGCM) or its related wiring harness and connectors.

The cause could be a faulty SGCM, an open or shorted harness, or a poor electrical connection.

It’s important to address this issue promptly as it can affect the performance of your vehicle. The repair time for this fault code is estimated at 1.0.

To fix the problem, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1a75 fault code.

Here are the symptoms to look out for:

  • The P1A75 fault code in an automobile can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON.

The P1A75 fault code can be caused by a faulty SGCM or poor electrical connections.

  • The automobile fault code P1A75 can be caused by a faulty Starter/Generator Control Module (SGCM).
  • It can also be caused by an open or shorted SGCM harness.
  • Additionally, a poor electrical connection in the SGCM circuit can also trigger this fault code.

Below are the possible fixes for the automobile fault code p1a75, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P1A75, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P1A75 can be diagnosed and fixed within an estimated repair time of 1.0 hour.

The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops.

Therefore, the total cost of diagnosis and fixing the P1A75 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P1A75 fault code relates to the StarterGenerator Control Module (SGCM) coolant temperature sensor 2 performance. The SGCM uses internal fluid temperature sensors to control the coolant pump and cooling fan. The thermistors used as internal fluid temperature sensors are not serviceable and their input parameters are not displayed on the scan tool.

The voltage signals from the sensors are high when the internal fluid temperatures are cold and low when they are hot.

What are the possible causes of the P1A75 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1A75 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.

How can I visually inspect the wiring harness and connectors related to the Starter/Generator Control Module (SGCM)?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light, 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. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.

What are the steps to take if I find damaged components or broken, bent, pushed out, or corroded connector’s pins while inspecting the wiring harness and connectors?

If you find damaged components or broken, bent, pushed out, or corroded connector’s pins while inspecting the wiring harness and connectors, follow these steps. First, check the “Possible Causes” listed above. Then, visually inspect the related wiring harness and connectors. Finally, look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins. This will help you fix the issue of the Engine Light ON (or Service Engine Soon Warning Light) caused by a faulty Starter/Generator Control Module (SGCM), SGCM harness being open or shorted, or SGCM circuit poor electrical connection.
