Code P0967 2014 GMC Sierra Description

The pressure control solenoid 2 is part of the control solenoid valve assembly which has no serviceable parts. The normally high-pressure control solenoid 2 regulates and directs the pressure control solenoid 2 oil pressure to the 3-5 reverse clutch regulator valve and 3-5 reverse clutch boost valve. Increasing pressure control solenoid 2 pressure increases pressure to the 3-5 reverse clutch. The Transmission Control Module (TCM) varies the current to the pressure control solenoid 2 through a low side driver. Decreasing the current to the pressure control solenoid 2 increases pressure control solenoid 2 oil pressure by closing OFF the solenoid exhaust port. Increasing the current to the pressure control solenoid 2 decreases pressure control solenoid 2 oil pressure by opening the solenoid exhaust port. Pressure control solenoid 2 power is supplied by the Transmission Control Module through a high side driver. The high-side driver protects the circuit and components from excessive current flow. If excessive current flow is detected, the high side driver will turn OFF. When the fault is corrected, the high-side driver will reset.
The Diagnostic Trouble Code (DTC) will be set when the Transmission Control Module detects an open or short to voltage on the clutch pressure control solenoid 2 control circuit, for 1 s.

Frequently Asked Questions about P0967 2014 GMC Sierra Code

What does the OBDII code P0967 indicate on a 2014 GMC Sierra?

The code P0967 indicates that the Pressure Control Solenoid "B" Control Circuit is experiencing high voltage in your 2014 GMC Sierra. This solenoid is part of the transmission's hydraulic system that controls the pressure.

What are common symptoms of the P0967 code in a 2014 GMC Sierra?

Symptoms of the P0967 code may include erratic transmission shifts, transmission slipping, decreased fuel efficiency, a transmission that may go into limp mode, and the Check Engine Light turning on.

What can cause the P0967 code to appear on a 2014 GMC Sierra?

Possible causes for the P0967 code include a faulty pressure control solenoid, issues with the transmission control module, wiring problems like shorts or opens in the solenoid circuit, or low transmission fluid levels.

How can I diagnose the P0967 code in my 2014 GMC Sierra?

Diagnosis should start with checking the transmission fluid level and condition. Then, use a multimeter to check for proper voltage and ground at the pressure control solenoid. Inspecting the wiring and connectors for damage, corrosion, or disconnection is also crucial. A scan tool may be necessary to monitor solenoid operation and verify the issue.

What are the repair steps for fixing the P0967 code on a 2014 GMC Sierra?

Repair steps might include replacing the pressure control solenoid if it's faulty, repairing or replacing damaged wiring or connectors, or changing the transmission fluid if it's contaminated or low. In some cases, reprogramming or replacing the transmission control module may be necessary.

Is it safe to drive my 2014 GMC Sierra with the P0967 code?

Driving with the P0967 code can lead to more serious issues like transmission failure. It is advisable to address the problem as soon as possible to avoid further damage and ensure safe driving conditions.

Can a faulty battery or alternator cause the P0967 code in a 2014 GMC Sierra?

While a faulty battery or alternator is less likely to directly cause the P0967 code, they can contribute to voltage irregularities that might affect the transmission control system. It’s a good idea to check these as part of a thorough diagnosis.

How does a technician verify that the P0967 repair was successful in a 2014 GMC Sierra?

After repairs, a technician will clear the code from the vehicle's computer and take the vehicle for a test drive to ensure that the transmission is functioning properly and the Check Engine Light does not return. Additionally, they might use a scan tool to confirm that the solenoid is operating within the manufacturer's specifications.
