P0823 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P0823 can be explicated as Gear Lever X Position Circuit Intermittent. If the error code P0823 is appearing, then it would mean that the PCM has registered some defect in the transmission shift mechanism range circuit, as pertains to a specific lever position.

The brighter you are, the more you have to learn! That’s why we are here to provide you more knowledge about the P0823 trouble code. This code is a generic trouble code, meaning it applies to all vehicles equipped with the OBD-II system, especially those made from 1996 up to present. It’s also more common among Audi, Citroen, Chevrolet, Ford, Hyundai, Nissan, Peugeot, and Volkswagen vehicles. Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model, powertrain configuration type, to another.

What causes this problem with the Gear Lever X Position Circuit Intermittent?

• The data which is not as per the parameters of the transmission shift solenoids, the torque converter lockup solenoid, vehicle speed sensors or other sensors is being registered by the PCM.
• This would then be read as non-correct transmission shifter range by the powertrain control module.
• This would give rise to this fault code and at the same time there would be an illumination of the malfunction indicator lamp.
• The transmission would be put into the limp-in mode by the powertrain control module
• Now if the transmission range sensor would not be as per the adjustment or there is some failure in the transmission range sensor, then it would give rise to the P0823 trouble code.

1. Engine Control Module - OBD Code P0823 can appear because of faulty Engine Control Module.
2. Fuel Injector - There can be some issues with the Fuel Injector due to which you may see P0823 code appearing over and over again. Visit us to buy best quality Fuel Injector online.
3. Fuel Injection Harness - Are you facing some faults in your Fuel Injection Harness? Don’t worry and get them replaced or else P0823 code can turn up.
4. Body Control Module Component - Common cause behind this P0823 error code can be some fault in Body Control Module Component. So, it will be a good decision to replace them now.
5. Powertrain Control Module - Body Control Module Component is perfectly fine but still but having that trouble code P0823 flashing? In such a situation your Powertrain Control Module might be faulty. Why don’t you think of getting that replaced?

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0823 here:

Common Symptoms

• Raspy shifting

If you want to easily diagnose this trouble code, then you must follow the steps which are mentioned here as below:

It is very important to use the correct tools to diagnose a problem with a very professional outlook

A diagnostic scanner, a reliable source of vehicle information, and a digital volt/ohmmeter (DVOM) will be required in order to arrive at an accurate diagnosis of a code P0823. In a lot of vehicles, there is a changeable resistance design of the transmission range sensor. You can find the switch over the transmission shift shaft, where the shift lever slides on over it. Now when there is a movement in the shift lever, the pivot of the range sensor would move to various contacts. Various levels of resistance are sent by switch contacts to the powertrain control module, according to the position of the shift lever.

These differing levels of voltage is then interpreted by the PCM as the gear selected by the shifter and utilizes this information to decide shift points, fuel metering, engine ignition timing and a lot of different other functions. The transmission, engine and ABS inputs is used by the PCM to decide whether the transmission is in the right gear for driving conditions, and then after that the powertrain control module would react on this information. Check the system wiring, connectors and constituents, and then mend/restore any open, shorted, defective or corroded items found, after that the entire system should be retested. If all wiring, connectors and other constituents seem to be in proper working condition, then you should connect the scanner to the diagnostic connector. If there are any stored trouble codes as well as freeze frame data then it should be recorded; this information will be helpful in diagnosing any intermittent conditions that may have consequence in this specific error code.

All the codes should be cleared up and the automobile should be taken out for a test drive to see if the code returns. If it is not appearing, then it means that there is an intermittent condition which may need to be allowed to worsen and return so that proper diagnosis can be done. If the code is returning away, then you should check the transmission range sensor for battery voltage/ground signals. If either ground or battery voltage circuits are open, any related control modules should be disconnected and use the digital volt/ohmmeter to inspect for continuity and resistance in both of the circuits.

Restore any system circuits or connectors which are faulty, and then the entire system should be retested. A manufacturer’s wiring schematic should be obtained and test all related circuits and the sensor itself for resistance and continuity. It should be then compared to the manufacturer’s specs. You can always repair and restore any circuits, connectors and constituents that do not comply with manufacturer’s specs. After that you should retest the entire system. Now if you find out that all the circuits comply with manufacturer’s factory specs, then a defective PCM should be suspected but remember that failure in the powertrain control module is very rare and there would be a need of complete reprogramming.
