The P2505 automobile fault code is a common issue that triggers the Engine Light ON or Service Engine Soon Warning Light. This code is usually caused by low battery voltage, a faulty Powertrain Control Module (PCM)Engine Control Module (ECM), or an open or shorted ECMPCM harness.

The importance of repairing this issue lies in the fact that it can lead to poor engine performance and reduced fuel efficiency.

The repair difficulty is moderate, and it takes approximately 1.0 hour to fix. To interpret the fault code, one should check the possible causes listed above and visually inspect the related wiring harness and connectors for any damage or corrosion.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2505 fault code. Here are the symptoms to look out for:

  • The P2505 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include difficulty starting the engine, stalling or rough idling, reduced engine power, and poor acceleration.
  • Additionally, the vehicle may experience issues with the transmission, such as harsh shifting or failure to shift gears.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe operation on the road.

The automobile fault code P2505 can be caused by low battery voltage, faulty PCMECM, open or shorted harness, and poor electrical connection.

  • The automobile fault code P2505 can be caused by low battery voltage.
  • It can also be caused by a faulty Powertrain Control Module (PCM) or Engine Control Module (ECM).
  • Another cause of this fault code is an open or shorted ECM/PCM harness.
  • Additionally, a poor electrical connection in the ECM/PCM circuit can also trigger this fault code.

To fix the p2505 automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code P2505, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors for any damage.
  • Look for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The factors that influence the cost of diagnosing and fixing the automobile fault code P2505 include the estimated repair time of 1.0 hour and the hourly rate charged by auto repair shops, which typically ranges between $75 and $150.

These factors are crucial in determining the overall cost of the repair, and it is essential to consider them when seeking professional assistance to fix the issue.

The P2505 code refers to the ECMPCM Power Input Signal. It is set when the ECMPCM Power Input is out of factory specifications. This code is triggered when the battery voltage is applied from the battery to the PCMECM through the main relay.

If the ignition switch is turned off, the ECMPCM is supplied with power through the battery power input line to control the basic operation of the vehicle.

What are the possible causes of the P2505 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P2505 fault code. This code is often caused by low battery voltage, a faulty Powertrain Control Module (PCM)/Engine Control Module (ECM), an open or shorted ECM/PCM harness, or a poor electrical connection in the ECM/PCM 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 related wiring harness and connectors to fix the P2505 fault code?

If you’re experiencing the P2505 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you can visually inspect the related wiring harness and connectors to fix it. The possible causes of this fault code include low battery voltage, faulty Powertrain Control Module (PCM)/Engine Control Module (ECM), ECM/PCM harness is open or shorted, and ECM/PCM circuit poor electrical connection. To fix it, check the possible causes listed above and visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.

What are the signs of damaged components that I should look for when fixing the P2505 fault code?

If you’re fixing the P2505 fault code, look out for the engine light being on or the service engine soon warning light. The possible causes include low battery voltage, a faulty Powertrain Control Module (PCM)/Engine Control Module (ECM), an open or shorted ECM/PCM harness, or a poor electrical connection in the ECM/PCM circuit. To fix it, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components such as broken, bent, pushed out, or corroded connector pins.
