Code P0968 Cadillac Description

The pressure control solenoid 3 is part of the control solenoid valve assembly which has no serviceable parts. The normally high-pressure control solenoid 3 regulates and directs the pressure control solenoid 3 oil pressure to the 4-5-6 clutch regulator valve and 4-5-6 clutch boost valve. Increasing pressure control solenoid 3 oil pressure increases oil pressure to the 4-5-6 clutch assembly. The Transmission Control Module varies the current to the pressure control solenoid 3 through a low side driver. Decreasing the current to the pressure control solenoid 3 increases pressure control solenoid 3 oil pressure by closing OFF the solenoid exhaust port. Increasing the current to the pressure control solenoid 3 decreases pressure control solenoid 3 oil pressure by opening the solenoid exhaust port. Pressure control solenoid 3 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.

Frequently Asked Questions about P0968 Cadillac Code

1. What does the OBDII code P0968 mean on a Cadillac?

P0968 indicates an open circuit issue in the Pressure Control Solenoid Valve 3 control circuit, which affects the transmission's ability to regulate hydraulic pressure.

2. What are the common symptoms of the P0968 code on a Cadillac?

Common symptoms include harsh or erratic shifting, transmission slipping, reduced fuel efficiency, and possible activation of the check engine light.

3. What causes the P0968 code to appear on a Cadillac?

This code can be caused by a faulty pressure control solenoid, damaged wiring or connectors in the solenoid circuit, a failed transmission control module (TCM), or low transmission fluid levels.

4. How can I fix the P0968 code on my Cadillac?

Inspect and repair any damaged wiring or connectors, replace the faulty pressure control solenoid if necessary, check and top off transmission fluid levels, or reprogram/replace the TCM if required.

5. Can I drive my Cadillac with the P0968 code active?

Driving with this code is not recommended, as it can cause further damage to the transmission and lead to unsafe driving conditions due to erratic shifting.

6. How is the P0968 code diagnosed on a Cadillac?

A technician will use a scan tool to confirm the code, inspect the wiring and connectors for damage, test the solenoid for proper functionality, and check the TCM for faults.

7. Is low transmission fluid a possible cause of the P0968 code?

Yes, low transmission fluid can lead to improper hydraulic pressure in the transmission, potentially triggering the P0968 code.

8. How much does it typically cost to repair the P0968 code on a Cadillac?

Repair costs can range from $150 to $500 or more, depending on whether wiring repairs, solenoid replacement, or TCM reprogramming/replacement is needed.

9. Can a bad transmission control module (TCM) trigger the P0968 code?

Yes, a malfunctioning TCM can cause the P0968 code by failing to properly control the pressure control solenoid.

10. How can I prevent the P0968 code from recurring on my Cadillac?

Regularly maintain your transmission by checking fluid levels, inspecting wiring and connectors, and addressing any transmission issues promptly to avoid circuit failures.
