Pressure Control Solenoid Control Circuit High
The P0967 code indicates that the Powertrain Control Module (PCM) has detected a high voltage or resistance in the control circuit of the pressure control solenoid. This solenoid regulates hydraulic pressure to the transmission's shift valves, and a high circuit condition typically points to a short to voltage, open circuit, or faulty solenoid. This can cause harsh shifting, slipping, or transmission overheating.
01. Most Common Causes
- Faulty pressure control solenoid
- Short to voltage in the solenoid circuit
- Open or high resistance in wiring/connectors
- Failed PCM (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or delayed shifting
- Transmission slipping or overheating
- Reduced fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Inspect wiring and connectors for damage, corrosion, or shorts.
Step 3: Test solenoid resistance with a multimeter (typically 4-6 ohms).
Step 4: Check for voltage at solenoid connector with key on (should be battery voltage).
Step 5: If wiring and solenoid are okay, test PCM output or replace PCM.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended. Driving with a high circuit condition can cause transmission damage due to harsh shifting or slipping.
How much does it cost to fix?▼
Repair costs range from $150 to $400, depending on whether the solenoid, wiring, or PCM needs replacement. Labor is typically $100-$200.
