P0968
Pressure Control Solenoid C Control Circuit/Open
Transmission
Generic OBD-II
Medium
What it means
P0968 means the transmission control module has detected an open (broken) control circuit for pressure control solenoid C. That solenoid regulates hydraulic pressure for shifting, so when the circuit fails the transmission often shifts harshly or drops into a protective limp mode. It's usually a failed solenoid or a wiring/connector fault.
Medium
Can I keep driving? Often the transmission drops into a fixed-gear limp mode — you can usually drive gently to a shop, but harsh shifts or slipping mean you shouldn't keep driving on it.
Common symptoms
What you'll notice
- Check-engine light on
- Harsh, delayed, or erratic shifting
- Transmission slipping or stuck in one gear (limp mode)
- Loss of some gears
Common causes
Most likely first
- Open circuit at pressure control solenoid C (failed solenoid coil)Likely
- Broken or open wiring in the solenoid circuitCommon
- Corroded or loose electrical connectorCommon
- Failed transmission control module (TCM)Less often
How to diagnose & fix
Work through it in order
- Scan freeze-frame and note the conditions when the code set.
- Inspect the solenoid's wiring and connector for opens, damage, or corrosion.
- Measure the solenoid's resistance against spec; replace it if open or out of range.
- Repair wiring; internal solenoids may require dropping the pan and valve body.
- Retest; if the circuit and solenoid are good, have the TCM tested.
FAQ
Quick answers
Is it safe to drive with P0968?+
Only briefly and gently. The transmission usually enters limp mode; continued hard driving with slipping or harsh shifts can cause internal damage.
Can I just clear P0968?+
It will come back until the open circuit or failed solenoid is repaired — this is an electrical fault, not a passing glitch.
