[SOLVED] P1245 Code – Fix Alternator Load Input Low For Optimal Performance

The automobile fault code P1245 indicates a problem with the alternator or generator in your vehicle.

The most common symptom is the engine light being illuminated or the service engine soon warning light coming on. This fault code can be caused by a faulty alternatorgenerator, a broken alternator belt, an open or shorted harness, poor electrical connections in the alternator circuit, or a damaged powertrain control module (PCM). To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion.

Additionally, look for any broken, bent, pushed out, or corroded pins in the connectors.

The repair time for this issue is estimated to be around 1.0 hour. It is important to address this fault code promptly to prevent further damage to your vehicle’s electrical system.

The P1245 fault code refers to a problem with the alternator load input in the vehicle’s Powertrain Control Module (PCM). The PCM is responsible for monitoring the generator load from the generatorregulator in terms of frequency. When this fault code appears, it means that the input is lower than what the load should be during normal operation.

This can occur when there is no generator output present, resulting in a low load input. It is important to address this issue promptly to ensure proper functioning of the alternator and electrical system in the vehicle.

What are the possible causes for the automobile fault code P1245 and how can I visually inspect them?

If you’re seeing the engine light on or the service engine soon warning light, the fault code P1245 could be the culprit. This code can be caused by a faulty alternator/generator, a broken alternator belt, an open or shorted alternator/generator harness, a poor electrical connection in the alternator/generator circuit, or a damaged powertrain control module (PCM). To visually inspect these possible causes, check the related wiring harness and connectors for any damage. Look out for broken, bent, pushed out, or corroded connector pins as well.

How can a faulty alternator/generator or a broken alternator belt trigger the engine light to come on?

When the engine light comes on, it could be due to a faulty alternator/generator or a broken alternator belt. Other possible causes include an open or shorted alternator/generator harness, poor electrical connection in the alternator/generator circuit, or a damaged Powertrain Control Module (PCM). To fix this issue, you should check the possible causes mentioned above. Conduct a visual inspection of the wiring harness and connectors, looking for any damage. Additionally, check for broken, bent, pushed out, or corroded pins in the connectors.

What steps can I take to fix the P1245 fault code and ensure a proper electrical connection in the alternator/generator circuit?

To fix the P1245 fault code and ensure a proper electrical connection in the alternator/generator circuit, start by checking the possible causes mentioned above. Take a close look at the wiring harness and connectors, visually inspecting for any damage. Pay attention to broken, bent, pushed out, or corroded pins in the connectors. This thorough inspection will help identify any issues and allow for the necessary repairs to be made.
