P0962 - Pressure Control Solenoid Control Circuit Low
The P0962 code indicates that the Powertrain Control Module (PCM) has detected a low voltage condition in the control circuit of the pressure control solenoid. This solenoid regulates hydraulic pressure within the automatic transmission to control shift feel and timing. A low circuit condition typically means the voltage is below the expected range, often due to a short to ground, open circuit, or faulty solenoid. This can lead to improper transmission operation, harsh shifts, or slipping.
1. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or erratic shifting
- Transmission slipping or delayed engagement
- Reduced fuel economy
2. Most Common Causes
- Faulty pressure control solenoid
- Open or shorted wiring in the solenoid control circuit
- Poor electrical connection (corroded or loose connector)
- Failed PCM (rare)
3. Step-by-Step Diagnosis
Step 1: Use a scan tool to retrieve all codes and freeze frame data.
Step 2: Inspect the transmission wiring and connectors for damage, corrosion, or loose pins.
Step 3: Measure resistance of the pressure control solenoid; compare to manufacturer specs (typically 2-6 ohms).
Step 4: Check for voltage and ground at the solenoid connector with the ignition on; should see battery voltage on one pin and a good ground on the other.
Step 5: If wiring and solenoid are okay, test the PCM output by backprobing the circuit; if no signal, PCM may be faulty.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as low transmission fluid pressure can cause internal damage. You may experience harsh shifting or slipping, which can worsen over time.
How much does it cost to fix?▼
The cost typically ranges from $150 to $400, including parts and labor. Replacing the solenoid itself is around $50-$150, plus diagnostic time and fluid replacement if needed.
