P0967
UniversalPressure Control Solenoid B Control Circuit High
Medium SeverityThis code indicates that the Powertrain Control Module (PCM) has detected a high voltage condition in the control circuit for Pressure Control Solenoid B. This typically results in incorrect line pressure within the automatic transmission, which can lead to shifting problems or transmission damage if not addressed.
⚠️ Before You Begin (Safety First)
Always ensure the vehicle is safely supported on jack stands if working underneath. Disconnect the battery before performing any electrical work. Transmission fluid can be hot; allow the vehicle to cool before checking or draining fluid. Wear appropriate personal protective equipment, including gloves and eye protection.
Common Symptoms
- Check Engine Light illuminated
- Harsh or erratic shifting
- Delayed engagement of gears
- Transmission slipping
- Poor fuel economy
- Transmission may enter 'limp mode'
Common Causes
- Faulty Pressure Control Solenoid B
- Open or short circuit to voltage in the solenoid control wiring
- Corroded or loose electrical connector
- Faulty Transmission Control Module (TCM) or Powertrain Control Module (PCM)
- Contaminated transmission fluid causing solenoid blockage
Frequently reported on: Ford F-150 (2004-2010), Chevrolet Silverado (2007-2013), Honda Odyssey (2000-2006), Dodge Ram 1500 (2002-2008), Toyota Camry (2002-2006)
Diagnostic Steps
- Check transmission fluid level and condition. Ensure it is clean and at the correct level.
- Inspect wiring and connectors leading to the transmission and the pressure control solenoid for any signs of damage, corrosion, or loose connections. Pay close attention to the harness leading to Pressure Control Solenoid B.
- Clear the code and test drive the vehicle to see if the code returns.
- Using a multimeter, test the resistance of Pressure Control Solenoid B according to manufacturer specifications (this may require dropping the transmission pan).
- If the solenoid is faulty and accessible, replace Pressure Control Solenoid B. This often involves dropping the transmission pan and replacing the filter and gasket.
👨🔧 When to Call a Professional
If you lack experience with automatic transmission diagnostics or internal transmission component replacement, it is strongly recommended to consult a professional mechanic. Incorrect diagnosis or repair can cause significant and costly transmission damage.
Commonly Asked Questions
What does a pressure control solenoid do?
A pressure control solenoid regulates the hydraulic pressure within the automatic transmission, which is crucial for smooth and timely gear changes.
Can I drive my car with a P0967 code?
While you might be able to drive, it is not recommended for long. Driving with this code can lead to harsh shifts, transmission damage, or leave you stranded if the transmission fails completely.
Is replacing <strong>Pressure Control Solenoid B</strong> a difficult DIY task?
Yes, it is typically considered an advanced DIY task. It often requires dropping the transmission pan, dealing with transmission fluid, and working with sensitive internal components.
What if the code returns after replacing the solenoid?
If the code returns, the issue might be with the wiring harness, the electrical connector, the transmission control module (TCM), or internal transmission mechanical problems. Further diagnosis by a professional is recommended.
Will contaminated transmission fluid cause this code?
Yes, severely contaminated or low transmission fluid can cause pressure control solenoids to malfunction or get stuck, leading to this or similar transmission fault codes.
