P0747 – OBD-II DTC

OBD-II DTC P0747 – Pressure Control Solenoid Performance or Stuck Off

DTC P0747 meaning

DTC P0747 refers to a diagnostic trouble code that indicates a problem with the pressure control solenoid in the transmission system. Specifically, it signifies that the pressure control solenoid is either performing poorly or is stuck in the “off” position. This solenoid is crucial for regulating hydraulic pressure within the transmission, which affects shifting performance and overall vehicle operation.

DTC P0747 symptoms

Common symptoms associated with DTC P0747 may include:

• Delayed or harsh shifting between gears
• Slipping transmission
• Increased engine RPM without corresponding acceleration
• Check Engine Light illuminated
• Transmission overheating

DTC P0747 causes

Several factors can lead to the occurrence of DTC P0747, including:

• Faulty pressure control solenoid
• Wiring issues or poor electrical connections
• Low transmission fluid levels or contamination
• Faulty transmission control module (TCM)
• Mechanical issues within the transmission

DTC P0747 seriousness

DTC P0747 is considered a serious issue as it can lead to significant transmission problems if not addressed. Potential consequences include:

• Increased wear and tear on transmission components
• Complete transmission failure
• Unsafe driving conditions due to erratic shifting

How to diagnose DTC P0747

To diagnose DTC P0747, follow these steps:

1. Use an OBD-II scanner to confirm the presence of the P0747 code.
2. Inspect the transmission fluid level and condition.
3. Check the wiring and connectors related to the pressure control solenoid for damage or corrosion.
4. Test the pressure control solenoid for proper operation using a multimeter.
5. Examine the transmission control module for faults.

How to fix DTC P0747 step-by-step instructions

To fix DTC P0747, follow these steps:

1. Address any low or contaminated transmission fluid by replacing it.
2. Repair or replace damaged wiring and connectors related to the pressure control solenoid.
3. If the pressure control solenoid is faulty, replace it with a new one.
4. Clear any stored codes using an OBD-II scanner.
5. Test drive the vehicle to ensure the issue is resolved and no new codes appear.

How to erase DTC P0747

To erase DTC P0747, follow these steps:

1. Connect an OBD-II scanner to the vehicle’s diagnostic port.
2. Turn on the ignition without starting the engine.
3. Navigate to the “Erase Codes” or “Clear Codes” option on the scanner.
4. Confirm the action to clear the trouble codes.
5. Disconnect the scanner and start the vehicle to check for any reoccurring codes.
