How to Diagnose and Solve P1587 Electronic Throttle Monitor Data Available Issues

As a car enthusiast, there’s nothing more frustrating than seeing an error code pop up on your dashboard. One such error code is the P1587 Electronic Throttle Monitor Data Available issue. But don’t worry, I’m here to help you understand and solve this problem.

Understanding the P1587 Code

Firstly, let’s understand what the P1587 code means. This code indicates that there’s a problem with the electronic throttle control system in your vehicle. The system controls the amount of air entering the engine, which is crucial for its performance. If this system malfunctions, it can lead to serious engine problems.

What Triggers the P1587 Code?

The P1587 code is triggered when the Powertrain Control Module (PCM) detects an issue with the electronic throttle control system. This could be due to a faulty throttle position sensor, a damaged throttle body, or even a software glitch in the PCM itself.

Diagnosing the P1587 Code

Now that we know what the P1587 code means, let’s move on to diagnosing the problem.

Step 1: Check the Throttle Position Sensor

The throttle position sensor measures the position of the throttle valve, which controls the amount of air entering the engine. If this sensor is faulty, it can trigger the P1587 code. Use a multimeter to check the sensor’s resistance and voltage. If the readings are outside the manufacturer’s specifications, replace the sensor.

Step 2: Inspect the Throttle Body

The throttle body controls the airflow into the engine. If it’s damaged or dirty, it can cause the P1587 code. Inspect the throttle body for any signs of damage or excessive dirt. If necessary, clean it using a throttle body cleaner.

Step 3: Check the PCM Software

Sometimes, the P1587 code can be triggered by a software glitch in the PCM. Check if there are any updates available for your PCM software. If there are, update the software to the latest version.

Solving the P1587 Code

After diagnosing the problem, it’s time to solve it.

Step 1: Replace the Throttle Position Sensor

If the throttle position sensor is faulty, replace it with a new one. Make sure to calibrate the new sensor according to the manufacturer’s instructions.

Step 2: Clean or Replace the Throttle Body

If the throttle body is dirty, clean it using a throttle body cleaner. If it’s damaged, replace it with a new one.

Step 3: Update the PCM Software

If there’s a software glitch in the PCM, update the software to the latest version. If the problem persists, consider replacing the PCM.

Conclusion

The P1587 Electronic Throttle Monitor Data Available issue can be a bit tricky to diagnose and solve. However, with a systematic approach and a bit of patience, you can fix this problem and get your car running smoothly again. Remember, if you’re not comfortable doing these steps yourself, it’s always best to seek professional help.

FAQs

1. Can I drive my car with the P1587 code?

While it’s possible to drive with the P1587 code, it’s not recommended. The issue can lead to serious engine problems if not addressed promptly.

2. How much does it cost to fix the P1587 code?

The cost to fix the P1587 code can vary depending on the cause of the problem. Replacing a throttle position sensor can cost between $100 and $200, while replacing a throttle body can cost between $200 and $600.

3. Can a software update fix the P1587 code?

Yes, a software update can fix the P1587 code if the issue is due to a software glitch in the PCM. However, if the problem is due to a faulty sensor or a damaged throttle body, a software update won’t fix the issue.
