 <<See All OBD Codes

See the error code P283A? Don’t know what to do? Here we have listed all that you need to know about the error code P283A. This generic OBD-II code transmission may not shift properly is also known as a shift fork "B" position circuit intermittent. For the movement of the vehicle, the transmission converts power that is produced by the engine. For changing gears, a number of transmissions make use of electric motors. The code P283A is stored when if the transmission control module determines that the transmission is not shifting as per the requirements.

It should be noted that in all there are two electric motors that are used to shift the gears in the transmission. There is one for gears 1-3-5 and the other one for gears R-2-4-6. Two shift drums are connected to the shift motor pinion through two ideal gears that perform the shifting. The maximum shift force is supposed to be 1500N (337 lb). These motors are fit into the transmission control module (TCM) and function independently of each other.

What causes this problem with the Shift Fork "B" Position Circuit Intermittent?

• Expired transmission control module (TCM) program (reprogram TCM)
• Malfunctioning transmission control module (TCM)
• Fault in the transmission assembly

1. Transmission Control Module - Are you currently having difficulties while downshifting when you're slowing down, coming to a stop, or manually trying to downshift? Well, it could all be due to a fault in your TCM. Tune into Parts Avatar for your new one available at just the right price.
2. Spark Plugs - Weary and damaged spark plugs can often be problematic. So, to add some spark to your ride you definitely need the perfect quality spark plugs offered at Parts Avatar. Isn’t that just the perfect deal?

4. Camshaft - Love hitting the roads? But tired of this error code P283A flashing? Then this is indicative of an underlying problem in the camshaft. Tune into Parts Avatar now for changing it immediately.

Have you ever wondered why is it so important to know the symptoms of the problem? Well, it is extremely essential to know the symptoms of the problem in order to detect it. Keeping this in mind, let’s throw some light on few common symptoms of OBD error code P283A:

Common Symptoms

• Increase in fuel consumption
• Also, the transmission may fail to shift properly

To correct this issue you might need to undergo few replacements for the defective parts such as:

• Repair or replace a damaged transmission control module as soon as possible
• Make sure you perform steps to mend an outdated transmission control module (TCM) program (reprogram TCM)
• A faulty transmission assembly should be repaired or replaced

Here are some steps which you should follow in order to diagnose this fault code P283A:

To start with, in such a condition, you are likely to hear loud noises like explosions from the rear of the vehicle while acceleration. The first step should be to check the carburetor to make sure that the fuel and air aptly balanced. If all this is functioning in order, then move onto thoroughly inspecting the distributor cap for any traces of cracks or hairline split as this can cause a backfire. Then the spark plugs should be inspected. Make sure that they are clean and are working in order. The engine gaskets should be checked for any traces of damage as they function for ensuring right gas exchange within the engine. The OBD-II code P283A particularly refers to the camshaft (cam) timing. The engine light illuminates along with the stored code if the cam timing is over-retarded in this case.

Common Mistakes When Diagnosing the P283A Code

Here only for our customers we have listed a few common mistakes that should be avoided while performing the diagnosis:

• Failed internal transmission
• A faulty transmission control module
• Wiring problems
• An outdated transmission control module software (should be updated, if required)
• Calibrate the transmission control module
