 <<See All OBD Codes

Baffled? Don’t know where to start the diagnosis? No worries, Parts Avatar to the rescue! Here we have listed all that you need to know about the error code P2843. This generic OBD-II code transmission may not shift properly is also determined as a shift fork "D" position circuit high. Well, it can be seen that the transmission constantly converts the power produced by the engine to movement of the vehicle. Particular transmissions employ the electric motors for changing gears. Whenever the transmission is not shifting properly, the transmission control module detects it and sets the error code P2843.

It is notable that in all there are two electric motors that are used to shift the gears in the transmission. One is used for the gears 1-3-5 and the other one is used for gears R-2-4-6. There are two shift drums connected to the shift motor pinion through the two ideal motors that help in gear shifting. The maximum shift force is evaluated to be at 1500N (337 lb). The transmission control module has two motors unified that work individually.

What causes this problem with the Shift Fork "D" Position Circuit High?

• A transmission control module (TCM) program that is outdated
• Malfunction in the transmission control module (TCM)
• Corroded transmission assembly

Have a look at some ways with which you can correct the P2843 code:

• Repair or replace a damaged transmission control module as per the requirements
• Make sure amendments are performed for reprogramming an outdated program in the transmission control module (TCM)
• Mend or restore a defective transmission assembly in order to get rid of the error code P2843

There is no need to get strained if your OBD code is still flashing up as we are here at your service. Have a look at our superior variety of transmission, TCM, transmission wiring, internal transmission and many more. Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this fault code:

A standard OBD-II trouble code scanner should be used to diagnose this trouble code P2843. The scanner will be used to check and view the freeze frame data and assess the code by a certified technician. The technician should also check for additional trouble codes stored. After the repairs have been performed, the codes should be retested and the vehicle should be restarted to see if the code pertains. If the code disappears it could likely be due to a faulty diagnose or may represent an intermittent issue.

Common Mistakes When Diagnosing the P2843 Code

For completely getting rid of an error code, you need to make sure that the code is diagnosed and treated accurately. So only for your convenience, we have listed here a few common mistakes that should be avoided while performing the procedure:

• Failures inside the transmission
• Faulty transmission control module (TCM)
• The transmission control module (TCM) should be calibrated as per the needs
• Update of the transmission control module (TCM) software
• Defective wiring
