P0962 Code: Pressure Control Solenoid “A” Control Circuit Low

The pressure control solenoid is a computer-controlled solenoid found in electronic automatic transmissions. This part helps regulate hydraulic system pressure, preventing excessive pressure from building up inside the transmission. The pressure control solenoid is operated by the powertrain control module (PCM).

If the PCM  detects an issue with the solenoid’s electrical circuit, on-board diagnostics (OBD) will log a P0962 code.

What Does the P0962 Code Mean?

Diagnostic trouble code (DTC) P0962 stands for “Pressure Control Solenoid ‘A’ Control Circuit Low.”

The PCM switches the pressure control solenoid on and off using pulse-width modulation. This causes the solenoid to push against an internal valve, opening and closing a specific hydraulic circuit. Regulating the hydraulic pressure helps the PCM engage the transmission clutches at the right time and pressure for a smooth gear shift.

The pressure control solenoid is responsible for maintaining a stable operating pressure throughout the transmission’s operating range. If the pressure control valve develops an issue, a P0962 code will be set.

Note: The definition of code P0962 might be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.

What are the Common Causes of the P0962 Code?

• Faulty transmission valve body
• Low transmission fluid level
• Defective pressure control solenoid
• Transmission control module failure
• Wiring issues
• Blocked hydraulic passages

What are the Common Symptoms of the P0962 Code?

• Illuminated check engine light
• Poor fuel economy
• Slipping transmission
• Overheating transmission
• Vehicle goes into limp mode
• Harsh shifting

How to Diagnose the P0962 Code

DTC P0962 is a generic powertrain code that can be logged in various makes and models. However, keep in mind that the steps for diagnosis and repair can vary, depending on vehicle specifications.

Diagnosing trouble codes also involves using specific tools, which can be tricky if you’re not familiar with the process. Under these circumstances, it might be best to have a certified mechanic inspect your vehicle. But if you think you have the right set of DIY skills, then you can go ahead and do it yourself.

Here is a video you could check out, so you can get an idea or two about what the diagnostic process might involve.

How to Fix the P0962 Code

Attempting to fix the P0962 code can be confusing if you’re not well-versed in automotive repair. To get the best results, it might be best to bring your vehicle to the nearest repair shop and let a trained professional perform the necessary repairs. But if you think you can fix the problem on your own, make sure to have the right guides before proceeding.

Keep in mind that there’s no umbrella fix that will cover all makes and models, so it’s important to have a guide that’s suited for your vehicle. Manuals like those from Chilton or an ALLDATA subscription contain vehicle-specific repair information, so you might want to check those out before you begin.
