• Solutions

The P2729 fault code indicates a problem with the Pressure Control Solenoid E in the transmission system. This code is triggered when the control circuit voltage is detected to be lower than expected. The pressure control solenoids play a crucial role in regulating transmission fluid pressure, which affects shifting performance and overall vehicle operation.

What are the symptoms of the P2729 code?

Drivers may experience various symptoms when the P2729 code is present, such as:

• Harsh or delayed shifting of transmission gears
• Slipping of the transmission or unexpected gear changes
• Warning lights on the dashboard, particularly the check engine light
• Increased fuel consumption due to inefficient shifting performance

What causes the P2729 code?

Several factors can lead to the P2729 code being triggered, including:

• Faulty Pressure Control Solenoid E
• Damaged wiring or connectors in the control circuit
• Low transmission fluid levels or contaminated fluid
• Issues with the transmission control module (TCM)
• Electrical shorts or open circuits within the solenoid's control wiring

How to fix P2729?

To resolve the P2729 fault code, consider the following steps:

• Inspect and replace the Pressure Control Solenoid E if necessary
• Check the wiring and connectors for any signs of damage or corrosion, and repair or replace as needed
• Ensure that the transmission fluid is at the correct level and is not contaminated
• Perform a diagnostic scan using a professional scanner to check for additional codes that may indicate further issues
• If issues persist, further inspection of the transmission control module may be required
