If your check engine light is on and you’ve got a P0606 diagnostic trouble code, don’t panic. This code is relatively common, and it can have a few different causes. In this article, we’ll tell you what a P0606 code means, what some of its common causes are, and what you can do to fix it.
What does error code P0606 mean?
The P0606 code is a generic diagnostic trouble code (DTC) that indicates a failure in the electronic control module (ECM). The ECM is the computer that controls the engine in your vehicle. When the P0606 code is stored, it means that the ECM has detected a problem with the internal circuit that controls the engine.
There are a number of potential causes for the P0606 code, but the most common is a problem with the ECM itself. Other potential causes include a problem with the wiring or connectors to the ECM, or a problem with the engine itself.
The best way to diagnose the P0606 code is with a professional diagnostic tool. This will allow you to access the ECM and read the codes that are stored there. Once you have the codes, you can then start to narrow down the potential causes and find the one that is most likely to be the cause of the P0606 code.
What is the symptom of error code P0606?
The most common symptom of error code P0606 is the Check Engine Light coming on. This can be accompanied by a loss of power, or the engine may run rough. In some cases, the engine may stall.
How serious error code P0606 is?
P0606 is a relatively serious error code that can indicate a number of different issues with your vehicle. If you see this code, it’s important to take your car to a mechanic as soon as possible to have it diagnosed and repaired. Depending on the underlying problem, P0606 can cause a number of different symptoms. These can include the check engine light coming on, the car running rough, and the car stalling. In some cases, P0606 can also lead to decreased fuel efficiency and increased emissions.
Common P0606 diagnosis mistakes
One common mistake that can be made when diagnosing the P0606 code is assuming that it is caused by a problem with the ECM. However, this is not always the case. In fact, the most common cause of this code is actually a problem with the wiring or connection to the ECM. This can be caused by a number of things, including a loose wire, a broken connection, or a short circuit. Another common mistake is assuming that the code is caused by a problem with the ECM itself. This is not always the case either. In fact, the most common cause of this code is actually a problem with the wiring or connection to the ECM. This can be caused by a number of things, including a loose wire, a broken connection, or a short circuit.
How to diagnose
P0606 Diagnostics Trouble Code
How to diagnose:
In order to diagnose a P0606 code, a technician will need to connect a scan tool to the vehicle’s OBD-II port. This will allow the technician to read any stored codes and live data. With this information, the technician can then begin to look for any evident issues. Common issues that can cause a P0606 code include a faulty ECM or PCM, a bad connection at the ECM or PCM, or a blown fuse.
How do you fix P0606?
There are a few things that you can do in order to fix the P0606 diagnostic trouble code. One thing that you can do is to check all of the wiring and connections to make sure that they are secure and not damaged in any way. Another thing that you can do is to check the PCM for any loose connections or damaged wires. If you find any problems with the wiring or connections, you will need to repair or replace them as necessary.
Approx Repair Cost
The average cost to repair a P0606 Diagnostics Trouble Code is between $80 and $120. This includes the cost of the parts and the labor required to replace them.
Check engine light
When the check engine light comes on in your car, it means that the onboard computer has detected a problem with the engine or emissions system. The computer stores a trouble code that can be read with a diagnostic scanner. The code will tell you what system is affected and can help you narrow down the cause of the problem.
There are many possible causes of a check engine light, so it is important to have the code read and the problem diagnosed by a trained technician. Ignoring the light can lead to more serious problems down the road.
Increased gas mileage
If you’re looking to increase your gas mileage, there are a few things you can do to make sure you’re getting the most out of your car. First, make sure you’re using the right type of oil for your car. Second, keep your tires inflated to the proper pressure. Third, get your car regularly serviced and tune-ups to keep it running efficiently. Finally, avoid excessive idling and driving at high speeds. By following these tips, you can maximize your gas mileage and save money at the pump.
Random misfire
A random misfire is a type of engine misfire that can occur at any time and is not related to the engine speed. This can be caused by a number of factors, including a dirty or faulty spark plug, a weakness in the ignition system, or a problem with the fuel injectors. If your vehicle is experiencing a random misfire, it is important to have it diagnosed by a professional as soon as possible.
Rough idle
If your car is idling roughly, it could be due to a number of different issues. The most common cause of a rough idle is an imbalance in the air to fuel mixture in the engine. This can be caused by a number of different things, including a dirty air filter, a clogged fuel injector, or a vacuum leak. Other causes of a rough idle can include a misfire, a faulty oxygen sensor, or a problem with the ignition system.
Step 1: Diagnose the vehicle
If the P0606 code is accompanied by any other P codes, addressing those first may fix the problem and eliminate the P0606 code. For example, a P0606 with a P0300 (random misfire) may be caused by a faulty ignition coil. In this case, replacing the ignition coil would fix the problem and eliminate the P0606 code.
If no other codes are present, the first step is to check all of the fuses related to the ECM. If any are blown, replace them and see if the P0606 code goes away.
Next, check all of the wiring and connectors going to and from the ECM. Look for any that are damaged, loose, or corroded. If any are found, repair or replace them as necessary and see if the P0606 code goes away.
If the wiring and connectors are all in good condition, the next step is to check the ECM itself for any damage. If any is found, replace the ECM and see if the P0606 code goes away.
If the ECM is undamaged, the next step is to check the data bus for any shorts or breaks. If any are found, repair or replace them as necessary and see if the P0606 code goes away.
If the data bus is in good condition, the next step is to check the power supply to the ECM. If the power supply is interrupted, it can cause the P0606 code to be set.
If the power supply is good, the next step is to check the ground circuits for the ECM. If any of the ground circuits are not functioning properly, it can cause the P0606 code to be set.
If all of the above steps have been completed and the P0606 code is still present, the next step is to check for any software updates for the ECM. If any are available, install them and see if the P0606 code goes away.
Step 2: Examine the power connections
If the power connections are damaged or loose, it can cause the P0606 code to be stored. Inspect the power connections and repair or replace them as needed.
Step 3: Examine the ground connections
If the ground connections are not clean or tight, this can cause all sorts of problems with electrical components. So it’s important to make sure that the ground connections are clean and tight. This can be done with a multimeter.
