How to Diagnose and Solve P1520 Electric Current Circuit Malfunction Issues

Are you a car enthusiast who loves to get your hands dirty? Or perhaps you’re a DIYer who enjoys the satisfaction of fixing things yourself? If so, you’re in the right place. Today, we’re going to delve into the world of car diagnostics, specifically focusing on the P1520 Electric Current Circuit Malfunction.

Understanding the P1520 Electric Current Circuit Malfunction

First things first, let’s understand what the P1520 Electric Current Circuit Malfunction is. This error code is typically triggered when the Engine Control Module (ECM) detects a problem with the electric current circuit. This could be due to a variety of reasons, including a faulty sensor, wiring issues, or even a malfunctioning ECM.

Common Symptoms of P1520 Electric Current Circuit Malfunction

How do you know if your car is experiencing this issue? Here are some common symptoms to look out for:

– Check Engine Light is on
– Engine stalling or misfiring
– Poor fuel economy
– Difficulty starting the engine

Diagnosing the P1520 Electric Current Circuit Malfunction

Now that we know what to look out for, let’s dive into how to diagnose this issue.

Step 1: Use an OBD-II Scanner

The first step in diagnosing this issue is to use an OBD-II scanner. This device can read the error codes from your car’s computer and help you identify the problem.

Step 2: Inspect the Wiring and Connectors

Next, you’ll want to inspect the wiring and connectors related to the ECM. Look for any signs of damage, corrosion, or loose connections.

Step 3: Check the Sensors

Finally, check the sensors related to the electric current circuit. This could include the throttle position sensor, the mass airflow sensor, or the oxygen sensor.

Solving the P1520 Electric Current Circuit Malfunction

Once you’ve diagnosed the problem, it’s time to fix it. Here’s how:

Step 1: Replace Damaged Wiring or Connectors

If you found any damaged wiring or connectors during your inspection, replace them. This is often the cause of the P1520 error code.

Step 2: Replace Faulty Sensors

If any of the sensors are faulty, replace them. This can often solve the problem.

Step 3: Reset the ECM

Finally, reset the ECM. This can often clear the error code and solve the problem.

Conclusion

Fixing a P1520 Electric Current Circuit Malfunction can seem daunting, but with a little patience and the right tools, it’s a task that can be tackled by any DIYer. Remember, the key is to diagnose the problem accurately and then take the necessary steps to fix it.
