Guide To P068A OBD Error Code Solutions

<<See All OBD Codes

Error code P068A can be defined as ECM/PCM Power Relay De-Energized Performance - Too Early. The engine control module receives power from the PCM power relay. Now if the PCM would detect some sort of variance in the supply of voltage from the power relay, then the P068A trouble code would start triggering up.

Thinking of gaining some more information about the P068A fault code? All the power inputs are monitored by the engine control module. The engine control module would set up the P068A trouble code when it would remain powered up after the ignition switch has been turned OFF.

What causes this problem with the ECM/PCM Power Relay De-Energized Performance - Too Early?

• Defective PCM power relay
• There can be blown fuse or fusible link
• Open or shorted circuit between the power relay and the PCM

Common Symptoms

• Car engine might not start at all
• Issue of hard or no start during the cold weather

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P068A:

• You must carefully repair and replace the alternator as well as its wiring and connectors
• The defective ignition switch should be replaced properly
• Make sure to replace the faulty PCM power relay

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

• The first and foremost thing which you will require for diagnosing this trouble code is a source of reliable vehicle information. From it you will glean diagnostic flowcharts, wiring diagrams, connector face views, connector pinout charts, and component locators
• Make sure to find component and circuit testing procedures and specifications. All this information would be required to successfully diagnose a code P068A
• Then the next step would be to connect the scanner to the vehicle diagnostic port and retrieve all stored codes and freeze frame data. It is very important to note of this information as it may prove useful if the code proves to be an intermittent one
• Now once you have recorded all the information, then you should clear the codes and test drive the vehicle until the code is reset or the PCM enters readiness mode
• If the PCM enters readiness mode, the code is intermittent and will be even more difficult to diagnose. The condition, which caused the P068A to be stored, may need to worsen before an accurate diagnosis can be reached. On the other hand, if the code fails to reset and there are no drivability symptoms exhibited, the vehicle can be operated normally
• Consult your vehicle information source for technical service bulletins (TSB) that replicate the code stored, vehicle (year, make, model, and engine), and symptoms exhibited. If you find the appropriate TSB, it may yield helpful diagnostic information
• If the P068A code is immediately reset, then you should proceed with a visual inspection of system related wiring and connectors. Harnesses that have been broken of unplugged should be repaired or replaced as required
• If wiring and connectors appear functional, use your source of vehicle information to obtain the appropriate wiring diagrams, connector face views, connector pin-out charts, and diagnostic flow charts
• Once you have the relevant information, test all system fuses and relays to make sure the PCM power supply relay is being supplied with battery voltage

Common Mistakes When Diagnosing The P068A Code

• Faults in the powertrain control module
• Powertrain Control Module power relay might be defective
• There can be some wiring issues
