Frequently Asked Questions
What does P0962 mean on a Duramax?
P0962 means Pressure Control Solenoid "A" Control Circuit Low. The control module has detected a lower than expected voltage on the pressure control solenoid "A" circuit.
Is P0962 a Duramax-specific code?
No. P0962 is a generic OBD-II code defined by SAE J2012, so it means the same thing on any vehicle that sets it. The exact conditions GM uses to set it on its diesels are in GM service information.
