P0962 - Pressure Control Solenoid Control Circuit Low
The P0962 code indicates that the transmission control module (TCM) has detected a low voltage or resistance in the control circuit of the pressure control solenoid. This solenoid regulates hydraulic pressure within the transmission to control shift timing and firmness. A low circuit condition can be caused by a faulty solenoid, damaged wiring, poor electrical connections, or a malfunctioning TCM. This issue can lead to erratic shifting, slipping, or harsh engagement.
01. Most Common Causes
- Faulty pressure control solenoid
- Damaged or corroded wiring/connectors in the solenoid circuit
- Low transmission fluid level or dirty fluid
- Faulty transmission control module (TCM)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or delayed shifts
- Transmission slipping or overheating
- Reduced fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan the vehicle for codes and record freeze frame data.
Step 2: Inspect transmission fluid level and condition; top off or replace if necessary.
Step 3: Visually check wiring and connectors for damage, corrosion, or loose connections.
Step 4: Test the pressure control solenoid resistance with a multimeter (specs vary by vehicle).
Step 5: If solenoid and wiring are okay, test TCM output signals or consult a professional.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as low transmission pressure can cause internal damage. Short trips to a repair shop may be acceptable if shifting is still normal.
How much does it cost to fix?▼
Repair costs range from $150 to $400, including parts and labor. Solenoid replacement is typically $100-$250, plus diagnostic fees.
