P2733 Fault Code

Pressure Control Solenoid F Stuck On

• What does that mean?
• Symptoms
• Causes
• Solutions

The P2733 fault code indicates a malfunction involving the Pressure Control Solenoid F, which is responsible for regulating hydraulic pressure within the transmission system. When this solenoid is stuck in the 'on' position, it can lead to excessive pressure, potentially causing shifting issues and transmission performance problems.

• This code is commonly associated with automatic transmissions and can result in various drivability issues.
• It is important to address this code promptly to prevent further damage to the transmission components.

What are the symptoms of the P2733 code?

Drivers may notice various symptoms when the P2733 code is present:

• Harsh or erratic shifting patterns while changing gears.
• Delayed engagement when shifting from park to drive or reverse.
• A complete loss of certain gears due to excessive hydraulic pressure.
• Overheating of the transmission, which may lead to further complications if not addressed.
• Transmission warning lights illuminated on the dashboard.

What causes the P2733 code?

Several factors can contribute to the P2733 code being triggered, including:

• A faulty Pressure Control Solenoid F that may be stuck due to internal wear or electrical failure.
• Electrical issues such as damaged wiring or poor connectors that affect the solenoid's operation.
• Low transmission fluid levels, which can impact hydraulic pressure control.
• A malfunctioning Transmission Control Module (TCM) that fails to regulate solenoid functions correctly.

How to fix P2733?

To resolve the P2733 fault code, the following steps are recommended:

• Begin with a thorough diagnostic scan to confirm the code and check for additional trouble codes.
• Inspect wiring and electrical connections related to the Pressure Control Solenoid F for any signs of damage or corrosion.
• If the solenoid is determined to be faulty, it should be replaced to restore proper function.
• Ensure that the transmission fluid is at the correct level and free from contamination, and replace if necessary.
• Clear the fault codes and take the vehicle for a test drive to ensure that the issue has been resolved.
