What is OBD-II Code P2867 – Shift Fork E Position Circuit Intermittent
If your check engine light has been illuminated and you have no idea what’s causing it, then this article will be beneficial for you. OBD-II Code P2867 is a trouble code that you might have seen on your vehicle, and in this article, we will be discussing this code in detail so you can have an understanding of what it means. As a mechanic, I have seen this code quite a few times, which is why I have decided to provide an explanation of what this code means and how to repair it.
What is OBD-II Code P2867?
OBD-II Code P2867 refers to a shift fork E position circuit intermittent issue. The powertrain control module (PCM) controls the shift solenoid valves to shift the gears depending upon the vehicle’s speed, throttle position, and engine load. In order to activate the right solenoid valve, the PCM sends a signal to the Transmission Control Module (TCM) that also monitors the position of the shift fork that engages the gears. The TCM also sends back a signal to the PCM to let it know that the shift has been made. If there is an issue with this communication, then the PCM will set Code P2867, indicating that the shift fork is not in the right position.
Symptoms of OBD-II Code P2867
After the check engine light turns on, you might notice one or more of the following symptoms that are related to the P2867 code:
1. Harsh shifting
2. Transmission won’t shift gear
3. Grinding noise from the transmission
4. Delayed engagement of the transmission
5. Engine stalling
Possible Causes of OBD-II Code P2867
There could be several reasons why your vehicle is showing this code. To help you make a diagnosis, here are some of the most common causes of OBD-II Code P2867:
1. Shift fork is stuck or damaged
2. Malfunctioning circuit within the transmission wiring
3. Malfunctioning shift solenoid
4. Damaged vacuum lines
5. Broken transmission
How to Fix OBD-II Code P2867
Although Code P2867 might sound complicated, it can be repaired quite easily if diagnosed correctly. Here are the steps you should follow to fix this code:
1. Clear all previous codes – The first step is to clear all the previous codes stored in the PCM by using a scan tool. This will help you focus on the current issue.
2. Check the shift fork – Next, you need to check the position of the shift fork to make sure it isn’t stuck or damaged. Remove the transmission pan to access the shift fork, and check if it moves freely, if damaged, or worn out. Replace if needed.
3. Check the wiring – After checking the shift fork, you need to examine the transmission wiring for any breaks or damage. A multimeter can be used to check that each wire’s resistance and signal strength are within specifications.
4. Check the shift solenoid – The next step is to check the shift solenoid for proper function. You can do this by testing its resistance and comparing it to the manufacturer’s specifications. Also, check for signs of damage or blockages within the valve.
5. Check the vacuum system – If everything else checks out, the vacuum system of the transmission should be examined for leaks or malfunction.
6. Repair or replace – After you have identified the issue, make the necessary repairs or replace any faulty components.
Frequently Asked Questions
1. What is an OBD-II scanner?
An OBD-II scanner is a tool that reads trouble codes stored within a vehicle’s onboard computer (PCM) and provides valuable diagnostic information.
2. How do I know if my vehicle is OBD-II compliant?
If your vehicle was manufactured after 1996, then it is OBD-II compliant, as this is the year when OBD-II became a standard for all vehicles.
3. What is the maximum number of codes that can be stored in the PCM?
The number of codes that can be stored in the PCM varies by manufacturer and model; however, most PCMs can store between 10-40 codes.
4. Can I still drive my vehicle with P2867 code?
It is not recommended to drive your vehicle with Code P2867, as it can lead to serious transmission issues, such as stalling or the transmission not shifting at all.
5. What is the cost to repair P2867 code?
The cost to repair Code P2867 varies depending on the severity of the issue, the make, and model of your vehicle. However, the average cost ranges from $250 – $500.
Conclusion
If you are experiencing OBD-II Code P2867 in your vehicle, then it’s necessary to take action to resolve the problem before it worsens. By following the steps mentioned above, you can diagnose and repair this issue without much hassle. However, if you’re wary of performing the repairs yourself, it’s best to take your vehicle to a trusted mechanic to avoid any additional issues. In any case, ensure that your check engine light is resolved to avoid any unwanted damage to your vehicle.
