P0600 Code: What It Means and How to Fix It

So maybe your check engine light is on or your car isn’t starting smoothly. You’ve hooked it up to your friend’s OBD code scanner, and your car is displaying a P0600 code. What on earth does that mean?

Don’t worry. We’ll explain what a P0600 code means for your vehicle, how you can diagnose the problem, and how to make any potential repairs.

Let’s begin! 

What Are the Symptoms of a P0600 Code?

The P0600 code is a scanning tool code that indicates an error with any one of the numerous sensors that are connected to your car’s engine control module (ECM).

You typically don’t get your first sign of car trouble from an OBD code scanner. Normally, you start to experience poor performance, which causes you to investigate. Here are a few potential symptoms of  a P0600 code:

  • – Your Check Engine light is on
  • – Your ABS, traction control, or transmission lights are on
  • – You experience a sudden drop in fuel economy
  • – Your car does not start, takes several tries to start, or stutters while starting
  • – Your car stutters or stalls while idling
  • – Shifting is erratic – or isn’t happening at all
  • – Poor acceleration

If you’re experiencing one or more of these symptoms, it’s a good idea to have your codes read. This can help alert you to the cause of your problem.

What Causes a P0600 Code?

Along with your car’s transmission control module (TCM) and powertrain control module (PCM), your ECM is responsible for automating several of your car’s motor functions. These include:

  • – Engine timing
  • – Fuel to air ratio
  • – Automatic transmission
  • – Tire pressure

 All of these functions require input from sensors, which allows your car’s computers to fine-tune their adjustments on the fly. When one of these sensors malfunctions, or when there’s a fault in the wiring, your car displays a P0600 code.

The reason it’s important to diagnose this code promptly is that you don’t know how dangerous it may be. For example, a failed tire pressure sensor is a trivial problem that you can fix whenever you like to. On the other hand, a failed sensor in your automatic transmission is a serious safety concern.

How Can I Troubleshoot a P0600 Code?

To troubleshoot your P0600 code, you need to determine whether the fault is in a sensor, the wiring, or your ECM itself. Here’s a step-by-step guide on how to tell the difference: 

  • – Use the OBD scanning tool to check for code history and pending codes. This can help you quickly pinpoint the source of the problem.
  • – Capture freeze-frame data for every code to determine what the conditions were when the code was triggered.
  • – Clear all codes and take the car for a test drive. Duplicate the conditions that caused each code to trigger.
  • – Check to verify that the code is once again displayed. It may just have been an error.
  • – Check the car’s battery voltage. Insufficient battery power can cause sensors to stop reading, triggering a P0600 code.
  • – Visually inspect all sensors and wires. Look for gaps in the insulation, corroded contacts, or severed wires.
  • – Use a multimeter to check all parts of the wiring harness for continuity including all ground cables.
  • – If all wires check out, follow your manufacturer’s procedure for diagnosing the ECU itself.

What Are Some Common Mistakes When Diagnosing a P0600 Code?

As with any electrical system repair, a P0600 diagnosis requires thoroughness at all steps of the process. Here are a few ways that beginners – and experienced mechanics – can fail to identify the problem:

  • – Not checking for other codes. This can save you a significant amount of time since a combination of two or three codes can help you pinpoint the problem immediately.
  • – Not performing a test drive. Sometimes, codes are wrong. Clearing a code and performing a test drive ensures that you’re not just chasing a ghost in the machine.
  • Failing to check ground circuits. Ground circuits are some of the most common sources of corrosion in your car’s electrical system. Forget to check them, and you could miss the source of your failure.
  • Forgetting to check battery voltage. Few car parts are as easy to replace as the battery. Why spend hours chasing an error code for no reason? Check your voltage first and save yourself some time.

How Can I Fix a P0600 Code?

The solution to a P0600 code is going to depend on what the specific cause was. As we’ve mentioned, the easiest possible fix is if your battery is delivering low voltage. You simply place in a new battery and you’ll be good to go.

In the event of a failed sensor, it will be necessary to replace the sensor, clear the codes, and perform a test drive to ensure that the failed sensor was the cause of the problem and not a symptom.

If a wire turns out to be the culprit, you’ll need to replace the wire. The same goes if you found corrosion on an electrical contact. If you’ve found corrosion, consider using a rust-proofing treatment to prevent the problem from getting worse in the future.

Finally, it’s possible that your car’s ECM is at fault. In this case, it will be necessary to repair or replace your ECM.
