 <<See All OBD Codes 

Confused? Don’t know what to do about it? Well, Parts Avatar is here at your service! Here we have mentioned all that you need to know about the OBD-II error code P2842. This generic OBD-II code transmission may not shift properly is also referred to as a shift fork "D" position circuit low. It should be noted that the transmission performs the function of altering the power produced by the engine to the movement of the vehicle. Numerous vehicles make use of the electric motors for changing the gears. The error code P2842 is set as soon as the transmission control module notifies an improper shifting of the transmission.

The gears R-2-4-6 and 1-3-5 each have one of the two electric motors. These electric motors are used to shift the gears in the transmission. Also, the gear shifting is performed by two shift drums that are attached to the shift motor pinion through two ideal gears. The maximum shift force is calculated to be 1500N (337 lb). These motors are fused in the transmission control module (TCM) itself and these functions independently.

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

• The transmission control module (TCM) program that is outdated
• A damaged transmission control module (TCM)
• Defect in the transmission assembly

1. Transmission Control Module - The transmission control module installed operates closely with many other parts that depend on its functionality including the engine, brake pedal position sensor, transmission fluid temperature sensor, turbine sensor, and throttle position sensor. So a damaged one should be replaced or repaired immediately.
2. Oxygen Sensors - A fault in this essential unit can lead to a big loss. It not only triggers the error code P2842 but also problems like engine stalls and a rough idle. Now get your oxygen sensors changed or repaired with Parts Avatar. Tune in now!
3. Powertrain Control Module - The powertrain control module functions as the central computer of the system. A defective one can trigger a lot of problems including increased fuel consumption and rough engine stalls. Tune into Parts Avatar for your new one immediately.
4. Engine Control Module - Don’t know what problems can be caused due a faulty engine control module? It can cause harsh shifting along with an error code P2842. Mend or restore it now!
5. Diagnostic Tools - Get your error code P2842 solved immediately by simply using your own diagnostic tools. Don’t know where to get yours from? Well, all you gotta do is tune into Parts Avatar for your new ones.
6. Electronic Control Unit - Don’t know what a jammed electronic control unit? It can raise issues like excessive mileage and strange noises. We recommend you to get your ECU changed or repaired immediately.

Want to diagnose the error code P2842? Well, then you should follow these steps in order to diagnose this fault code:

• An advanced OBD-II trouble code scanner should be applied to diagnose this trouble code P2842. The scanner should be used to check and view the freeze frame data and assess the code by a qualified mechanic.
• The mechanic should also check for additional trouble codes stored. After the repairs have been performed, the codes should be retested and the vehicle should be test driven to see if the code persists.
• If the code vanishes it could likely be due to a malfunctioning diagnose or may display an intermittent issue. We thoroughly advise you to seek professional help if you are not trained enough to crack the code by yourself.

Common Mistakes When Diagnosing the P2842 Code

Don’t want a misdiagnose? Want to save your hard-earned money from being blown away on expensive after repairs? Then all you got to do is avoid these mistakes that we have listed here:

• Defect in the transmission (internal)
• A fault in the transmission control module
• Calibrate the transmission control module
• It is important to update the transmission control module (TCM) software
• Damaged wiring
