Measure voltage at solenoid A connector with key on
-
Check for short to ground on the solenoid control wire
-
Test solenoid resistance and compare to specifications
-
Inspect connector for oil contamination or corrosion
Frequently Asked Questions
Can oil leaking onto the connector cause P0962?
Yes, oil leaking from a worn solenoid seal can reach the electrical connector and cause a short circuit. Clean the connector and replace the solenoid seal.
What is the normal resistance for a pressure control solenoid?
Typical resistance ranges from 5 to 20 ohms depending on the application. Consult your vehicle service manual for the exact specification.
Is P0962 more serious than P0961?
P0962 indicates a more definitive electrical fault than the performance issue of P0961. However, both should be addressed promptly to prevent potential engine damage.
