<<See All OBD Codes

See the error code P2846 flashing again and again? Don’t know where to start the diagnosis from? No worries, you have arrived at just the right place! We have written down here all that you need to know about the OBD-II error code P2846. This generic OBD-II code shift fork "B" position sensor incorrect neutral position indicated is also known as transmission may not shift properly in simple terms. The transmission plays the role of altering the power generated by the engine to the movement of the vehicle. A number of transmissions make use of the electric motors when they want to change the gears. The error code P2846 is set whenever the transmission control module identifies false shifting of the transmission.

Well, you should note that there are two electric motors present that help in shifting the gears in the transmission. One for the gears 1-3-5 and the other one is for the gears R-2-4-6. The two shift drums that are linked to the shift motor pinion via two ideal gears perform the gear shifting. The highest shift force is 1500N (337 lb.). The motors are fixed into the transmission control module (TCM) and function independently.

What causes this problem with the Shift Fork "B" Position Sensor Incorrect Neutral Position Indicated?

• Old transmission control module (TCM) program
• Failed transmission control module (TCM)
• Corroded transmission assembly

1. Transmission Control Module - Defective transmission control module? Don’t know how they can harm the system? Well, a defective transmission control module also at times becomes the reason behind the problems faced while downshifting or when slowing down. Contact Parts Avatar, your one stop destination to get your hands on our new transmission control module.
2. Oxygen Sensors - Facing the error code P2846? An inferior quality oxygen sensor can always be hazardous for the system also it is one of the primal causes behind the occurring of the error code P2846. Tune into Parts Avatar for supreme quality oxygen sensor at economical prices.
3. Powertrain Control Module - A distorted powertrain control module can end up being the chief host inviting the error code P2846. So, replacing one can be one of the wisest decisions to avoid a problematic system and problems like harsh shifting.
4. Engine Control Module - The ECM serves the purpose of helping the system function well. If the ECM fails or has any problems it can lead to performance issues with the vehicle like misfires, hesitation, loss of power, and sometimes even decreased fuel economy. Mend or restore it now!
5. Diagnostic Tools - Using high grade diagnostic tools can help you a lot in accurately diagnosing the error code. Don’t have yours? Now, you can buy your own diagnostic tools from Parts Avatar.
6. Electronic Control Unit - Well, are you aware of the fact that the ECU is a chief auto part of your car's onboard computer. It functions to regulate many systems and subsystems in the car's engine, drive train and other major components. Tune into Parts Avatar for you new one.

Here we have listed how you can simply diagnose the error code P2846:

• To start the diagnosis, make note that a scanner (or code reader) and a digital volt/ohmmeter will be helpful in precisely diagnosing this code-storing condition.
• Begin your diagnosis with a visual inspection of system wiring, connectors, and components.
• Repair or replace any open, shorted, damaged, or corroded items as required and retest the system to make sure that repairs were successful.
• If the system wiring, connectors, and components appear to be in conventional working order, connect the scanner to the diagnostic connector and record all stored trouble codes and freeze frame data.
• This information can be highly important in diagnosing intermittent conditions that may have stimulated the code being stored.
• After the codes are retested, operate the vehicle to see if the code returns. If the code fails to immediately return, you may have an intermittent condition.

Common Mistakes When Diagnosing the P2846 Code

We have listed here for our precious customers a few common mistakes that should be avoided while performing the diagnosis:

• A jammed transmission (internal failure)
• Broken transmission control module (TCM)
• Calibration in the transmission control module (TCM)
• Upgrade the transmission control module (TCM) software
• Wiring problems in the system
