Code P0960 2016 GMC Sierra Description

The line pressure control solenoid is part of the control solenoid valve assembly which has no serviceable parts. The normally high line pressure control solenoid regulates and directs the pressure control solenoid oil pressure to the isolator/pressure regulator valve. Increasing pressure control solenoid line pressure increases transmission line pressure. The Transmission Control Module (TCM) varies the current to the line pressure control solenoid through a low side driver. Decreasing the current to the line pressure control solenoid increases line pressure control solenoid oil pressure by closing OFF the solenoid exhaust port. Increasing the current to the line pressure control solenoid decreases line pressure control oil pressure by opening the solenoid exhaust port. Line pressure control solenoid 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 the 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 circuit on the line pressure control solenoid valve control circuit for 1 s.

Frequently Asked Questions about P0960 2016 GMC Sierra Code

What does the OBDII code P0960 mean on a 2016 GMC Sierra?

Code P0960 indicates an issue with the line pressure control solenoid valve control circuit, specifically that it is open or not functioning properly.

What are the common symptoms of code P0960 in a 2016 GMC Sierra?

Symptoms include harsh or erratic shifting, transmission slipping, decreased fuel efficiency, and the illumination of the check engine light.

What causes the P0960 code to appear on a 2016 GMC Sierra?

Common causes include a faulty line pressure control solenoid, damaged or corroded wiring in the control circuit, a failed transmission control module (TCM), or low transmission fluid.

Can low transmission fluid cause the P0960 code?

Yes, low transmission fluid can lead to improper line pressure control, which may trigger the P0960 code.

How do you diagnose the P0960 code on a 2016 GMC Sierra?

Diagnosis involves scanning for codes, inspecting the wiring and connectors for damage, testing the line pressure control solenoid for continuity, and checking the transmission fluid level.

How much does it cost to fix the P0960 code on a 2016 GMC Sierra?

Repair costs vary but typically range from $150 to $400, depending on whether the issue is wiring-related or requires solenoid replacement.

Can you drive a 2016 GMC Sierra with a P0960 code?

Driving with this code is not recommended as it can lead to further transmission damage or unsafe driving conditions due to poor shifting performance.

How do you fix the P0960 code on a 2016 GMC Sierra?

Common fixes include replacing the faulty line pressure control solenoid, repairing or replacing damaged wiring, and ensuring the transmission fluid is at the correct level.

Will clearing the P0960 code solve the problem?

Clearing the code without addressing the root cause may temporarily turn off the check engine light, but the issue will likely return.

Does the P0960 code indicate a serious problem?

Yes, it can be serious as it affects the transmission's ability to regulate line pressure, potentially leading to long-term damage if not resolved promptly.
