Error Code P0C23: What It Means & What To Do?

<<See All OBD Codes

The trouble code P0C23 can be elucidated as Auxiliary Transmission Fluid Pump Control Module Circuit/Open. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile. The motor control module is a part of the drive motor generator power inverter control module and the electric motor is controlled by it. The high voltage current driving the transmission is monitored by the motor control module. Now if the current is very less, then in that case the transmission would not be able to move the automobile. Whenever the motor control module would detect this, then it would give rise to P0C23 fault code. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code.

Are you tensed because the P0C23 fault code is flashing? We have everything which you need and at equitable prices. We promise that you will never regret your decision. This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another. The auxiliary transmission fluid pump is being monitored by the engine control module. This trouble code would be set by the ECM when the auxiliary transmission fluid pump would not be as per the specifications set by the manufacturer.

What causes this problem with the Auxiliary Transmission Fluid Pump Control Module Circuit/Open?

• Malfunctioning auxiliary transmission fluid pump
• Auxiliary transmission fluid pump harness might be unlocked
• The auxiliary transmission fluid pump circuit might have bad electrical connection

1. Power Relay - Damaged power relay will affect the pump circuit and thus hamper the performance of the transmission fluid pump going from delays response to not working at all. Thus, replace it now!
2. Fuse - Fuses are present along any component to protect it from damaging from excessive voltage transfer. Blown fuses are usually the easiest to replace and the least costly too. Thus, replace it now!
3. Engine Control Module - Dead cells in batteries can cause a failure in the engine control module. Many times, a battery is left in the rig long after a cell has died. This would affect the grounding in the car battery.
4. Transmission Control Module - The TCM monitors the functioning of the transmission system and will store OBD code error P0C23 if the fluid pump does not function properly. Contrary, the TCM can also be faulty and might need reprogramming and replacement. Thus, replace it now!
5. Powertrain Control Module - If there are some faults in the PCM, then it may throw off the timing and fuel settings of the engine, which can negatively affect the performance. A flawed PCM may cause the vehicle to experience a reduction in fuel efficiency, power as well as acceleration.
6. EEPROM - The electrically erasable programmable read-only memory, if at fault, will affect the functioning of the TCM and can result in wrong OBD code error getting stored in the system, resulting in performance issue and physical damages to various transmission components.
7. Electronic Control Unit - Do you know that the poor performance or unexplained drops in fuel economy or efficiency are often associated to onboard car computer problems, or defective ECU issues?
8. Diagnostic Tools - Use factory grade diagnostic tools to resolve OBD code P0C23 error. Buy new diagnostic tools and equipment for us.

Common Symptoms

• Visibility in the check engine light
• There might be some issues in the operation of the fuel pump due to which the car engine might not start
• Car engine might start losing power
• Issues related to engine stalling

Looking out for some ways with the help of which you can correct this fault code? Then you have arrived at the correct place. We are here to help you out, so you must check out the steps mentioned below as follows:

• It is essential to restore the flawed fuel pump relay
• Repair or replace the quirky IFS if there are some signs of corrosion
• Rehabilitate the defaults in the wiring as well as connectors
• The malfunctioning car battery should be repaired or replaced as per the need
• The powertrain control module should be restored to working order
• Recondition the non-functioning exhaust pressure sensor
• It is necessary to perform proper service of the unsound automatic transmission module
• Adjust the flawed turbocharger

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of oil pressure sensor, oil pressure switch, turbo intercooler, egr sensor, turbo supercharger, transmission control module and many more. Now all your problems would vanish within no time.

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

After verifying the P0C23 code with an OBD-II scanner, the mechanic should begin with a visual inspection of all electrical components, especially looking for leaking fluid that could have caused shorts or corrosion. Any issues should be repaired, and the code should be cleared from the system. If the code reappears after a retest, the mechanic should then move on to performing voltage tests and resistance tests on the sensor, and comparing the information to the manufacturer’s specifications. If the readings are within the correct limits, then the sensor needs to be replaced. However, if the readings are not within the correct limits, then the issue lies elsewhere. The mechanic should continue checking each possible cause, clearing the code and retesting the system after each attempt, to be sure that the correct solution is found.

Common Mistakes When Diagnosing The P0C23 Code

• Many people make a big mistake of not verifying the battery voltage. Make sure that it is not low and at the same time all the connections are in good working condition as they might cause an intermittent drop in the voltage in the car electrical system.
• Make sure to examine the electrical connections at the fuel pump relay as well as the IFS for any loose connections on the secondary side.
