• Causes
• Solutions

The P0970 fault code indicates an issue with the Pressure Control Solenoid C Control Circuit being low. This code is typically related to the transmission system and its components that manage hydraulic pressure. When this circuit is not functioning correctly, it can lead to various issues affecting vehicle performance and transmission operation.

What are the symptoms of the P0970 code?

Vehicles with a P0970 code may exhibit several symptoms, such as:

• Harsh or unexpected shifting of the transmission
• Delayed engagement when shifting gears
• Check Engine Light (CEL) illuminating on the dashboard
• Reduced fuel efficiency due to improper transmission function
• Overheating of the transmission due to ineffective hydraulic pressure management

What causes the P0970 code?

The low control circuit signal can be caused by a number of factors, including:

• A defective Pressure Control Solenoid C
• Damaged wiring or connectors in the solenoid circuit
• A faulty engine control module (ECM) or transmission control module (TCM)
• Poor electrical connections or shorts
• Low transmission fluid levels or contamination
• Mechanical failure within the transmission itself

How to fix P0970?

To resolve the P0970 fault code, you can follow these steps:

• Check the vehicle's transmission fluid level and condition, and replace it if necessary.
• Inspect the wiring and connectors related to the Pressure Control Solenoid C for any signs of damage or corrosion.
• Test the Pressure Control Solenoid C for proper operation using a multimeter.
• If the solenoid is faulty, replace it and clear the fault codes from the ECM/TCM.
• Consider reprogramming or replacing the ECM/TCM if the issue persists.
