Pressure Control Solenoid "C" Control Circuit/Open
The P0968 code means the vehicle's onboard diagnostic system has detected: Pressure Control Solenoid "C" Control Circuit/Open. This is a serious severity code.
- Keep driving?
- Short distances only
- DIY difficulty
- hard
- Estimated cost
- $150 - $900 (external solenoid or wiring at the low end; internal transmission solenoid work at the high end)
Read and clear transmission codes. Many trans codes are caused by low or burnt fluid -- check level and color before assuming the worst.
Basic scanners only read engine codes. This reads transmission, ABS, and airbag too.

What Are the Symptoms of P0968?
- Check Engine Light on
- Harsh, delayed, or missing shifts
- Transmission may enter limp mode (often locked in one gear)
- Symptoms can vary with fluid temperature
What Causes P0968? (Most Likely First)
- Failed Pressure Control Solenoid "C" High
- Low or contaminated transmission fluid - the cheapest thing to rule out first High
- Wiring or connector fault at the transmission case connector Moderate
- Valve body wear or debris holding the solenoid circuit off-spec Moderate
Can I Still Drive with P0968?
Short distances only. P0968 is rated serious severity. Keep trips short and get it diagnosed soon rather than waiting for symptoms to worsen.
Frequently Asked Questions
What does P0968 mean?
P0968 is a generic OBD-II code defined by SAE J2012 as "Pressure Control Solenoid "C" Control Circuit/Open". It means the control module detected an open circuit - a broken wire, disconnected connector, or failed component winding
Can I keep driving with P0968?
Short trips only. This fault can worsen or put the system into a protective mode without much warning, so have it diagnosed promptly.
Does P0968 mean the same thing on every car?
Yes. P0968 is in the generic (SAE J2012) range, so the definition is standardized across manufacturers. The specific component location and repair procedure still vary by vehicle - check your service information.
Mechanics Guide Step-by-step diagnosis
How Do You Diagnose P0968?
-
Check transmission fluid level and condition first - burnt or low fluid causes solenoid codes and is cheap to fix.
-
Command the Pressure Control Solenoid "C" with a capable scan tool and watch for a response.
-
Measure solenoid resistance at the case connector against the service-manual spec.
-
Inspect the external harness and case connector for damage and fluid intrusion.
-
If electrical tests pass, the fault is internal - valve body or solenoid pack service.
