Pressure Control Solenoid A Control Circuit Open
What does P0960 mean?
The P0960 code means the vehicle's onboard diagnostic system has detected: Pressure Control Solenoid A Control Circuit Open. This is a moderate severity code.
Common Symptoms
- Check Engine Light illuminated
- Rough idle or stalling
- Engine oil pressure warning light may come on
- Reduced engine performance
Probable Causes (Ranked by Likelihood)
- Failed pressure control solenoid A Very High
- Open circuit in solenoid A wiring High
- Disconnected connector at solenoid A Moderate
- ECM output driver failure Low
Step-by-Step Diagnostic Procedure
-
Locate pressure control solenoid A and check its connector
-
Measure solenoid resistance with a multimeter
-
Test for continuity in the wiring from ECM to solenoid
-
Command the solenoid with a bidirectional scan tool
Frequently Asked Questions
What does pressure control solenoid A do?
Pressure control solenoid A regulates oil pressure in a specific engine or transmission circuit. In an engine context, it may control variable valve timing oil pressure or oil pressure regulation.
Can I drive with P0960?
You can drive short distances, but if the solenoid controls a critical oil pressure circuit, continued driving could lead to engine damage. Have it diagnosed promptly.
Is the solenoid easy to access?
Access depends on the specific application. Some pressure control solenoids are externally mounted and easily replaceable, while others may require significant disassembly.
