Guide To P2793 OBD Error Code Solutions

<<See All OBD Codes

The trouble code P2793 can be explicated as Gear Shift Direction Circuit. If the transmission control module would detect a variation in the voltage coming from the gate select direction circuit signal delivered performance that is outside the parameters set by the automobile manufacturer, then it would store the P2793 fault code. This would give rise to the flashing up of the check engine light

Do you want to gain some more knowledge about the P2793 trouble code? This error code would start indicating when the powertrain control module would detect a malfunction in the gate select direction circuit for a specific ear lever position or direction. The transmission gate select direction sensor would then input the data to the PCM where it is used to calculate engine RPM, fuel delivery strategy, and engine timing, among other things. This error code would apply to automobiles equipped with dual clutch adaptive transmissions, automated manual transmissions, manual transmissions and automatic transmissions.

What causes this problem with the Gear Shift Direction Circuit?

• The transmission shifter might be flawed
• There can be distorted range sensor
• Quirks in the body control module (bcm)
• Shift lever assembly might be damaged

1. Engine Control Module - Want to know the most common reason behind the failure in the engine control module? Corrosion or damage because of moisture can cause ECM failure. Corrosion might enter the ECM through the wiring harness and moisture can enter by a failure in the seals in the ECM itself.
2. Manual Transmission Shifter - If your automobile is not going into gear at all, then it might not be a defective transmission. It can just be a faulty transmission shifter cable. It would be nice if you get it replaced on time with us at affordable prices.
3. Powertrain Control Module - The PCM makes the engine and transmission work in tandem. Any issue with the powertrain control module will cause major problems with the efficient running of the vehicle.
4. Transmission Fluid Pump - Harsh shifts and audible transmission noise are the major symptoms of faulty fluid pump. This leads to decreased performance and chances of increased physical damages to the transmission components. Thus, replace faulty pump now!
5. Electronic Control Unit - If your vehicle fails to start for no apparent reason, this is also a good indicator that there can be some issues with the ECU. If you check the car battery, starter and other common electrical components, and the vehicle still does not start, a quirky electronic control unit should be the next logical thing to consider.
6. Diagnostic Tool - In order to fix these errors, you need a few diagnostic tools to get your car problems pointed out easily. Our diagnostic tools collection will come in handy to do so and resolve all your vehicle problems. Visit today!

It is vital 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 P2793 here:

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

• This is a general type of error code which is diagnosed with the help of a scanner. The gear shift direction sensor is utilized to decide (for the PCM) which gear the transmission is placed in at any given interval, as well as acting as a neutral safety switch for engine ignition. Keep in mind that many gate selection direction sensors are of a variable resistance variety.
• The switch is situated in or near the transmission shifter assembly. Now when the shift lever would be moved (via the shift lever in the cockpit and the shifter cable) the gate selection direction sensor pivot is moved to various contacts.
• The varying levels of voltage are read by the powertrain control module, regulated by the differing levels of resistance in the switch contacts, as the gears in which the transmission shifter are placed. The PCM would then decide the shift strategy, fuel delivery theory, engine ignition timing, and other drivability functions accordingly.
• As transmission, ABS, and engine inputs are received by the powertrain control module, it decides whether or not the transmission is in the correct gear for the driving conditions and reacts accordingly. You must start your diagnosis with a visual inspection of system wiring, connectors, and constituents.
• Make sure to repair or replace any open, shorted, damaged, or corroded items as per the requirement and then the entire system should be retested to make sure that repairs were successful. If the system wiring, connectors, and components appear to be in good working order, then you should connect the scanner to the diagnostic connector and record all stored trouble codes as well as the freeze frame data.
• This information can prove to be extremely helpful in diagnosing intermittent conditions that may have contributed to this code being stored. Now once all the codes have been cleared, then you should operate the vehicle to see if the code returns. If the code fails to immediately return, then you might have an intermittent condition.
• Intermittent conditions can prove to be quite challenging to diagnose and in extreme cases it should be allowed to worsen before a right diagnosis can be made. If the code returns back immediately, then you should check for battery voltage and ground signals at the gate selection direction sensor.
• If either the ground or battery voltage circuits are open, then utilize the digital volt/ohmmeter to check for continuity (disconnect all related control modules from the circuit before inspecting circuit resistance or controller damage may occur) and resistance in both circuits. Repair or restore system circuits/connectors as per the requirement and retest the system to ensure that repairs were successful.
• Use the manufacturer’s wiring diagram for the gate selection direction sensor, check all associated circuits and the sensor for resistance and continuity and compare your findings with specifications set by the manufacturer.
• Repair or replace system circuitry, connectors, and/or components that fail to coincide with specifications set by the manufacturer. The system should be retested to ensure a successful repair. If all circuits coincide with manufacturer’s specifications, suspect a faulty powertrain control module. Just remember that PCM failure is rare and replacement would need reprogramming.

Common Mistakes When Diagnosing The P2793 Code

• Flaws in the body control module
• There can be some issues in the shift lever assembly
• Failure in the car wiring
