The P0967: Pressure Control Solenoid ‘B’ Control Circuit High refers to an issue where the pressure control solenoid ‘B’ circuit is receiving higher than expected voltage. This can cause the solenoid to malfunction, affecting transmission fluid pressure regulation and potentially leading to poor shifting performance.
P0967 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P0967: Pressure Control Solenoid ‘B’ Control Circuit High |
| Is it serious? | Yes, as high voltage can cause solenoid damage and lead to improper transmission pressure regulation. |
| Possible causes | – High voltage in the pressure control solenoid ‘B’ circuit – Faulty pressure control solenoid ‘B’ – Wiring or connector issues |
| How to diagnose? | – Check the circuit for high voltage – Inspect wiring and connectors – Replace the pressure control solenoid ‘B’ if necessary |
P0967 Meaning
The P0967: Pressure Control Solenoid ‘B’ Control Circuit High code indicates that the voltage in the pressure control solenoid ‘B’ circuit is above the acceptable range. This excessive voltage can cause the solenoid to malfunction, leading to transmission pressure control issues, poor shifting, and overall transmission performance problems.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for additional fault codes that may give further insight into the high voltage issue. | OBD-II Scanner |
| Test for High Voltage | Use a multimeter to test for high voltage in the pressure control solenoid ‘B’ circuit. Compare the readings with the manufacturer’s specifications. | Multimeter |
| Inspect Wiring and Connectors | Inspect the wiring and connectors for damage, corrosion, or loose connections that may be causing high voltage in the circuit. | Flashlight, Multimeter |
| Test the Solenoid | Test the pressure control solenoid ‘B’ for proper functionality. Replace the solenoid if it is faulty or receiving excessive voltage. | Diagnostic Tool, Replacement Solenoid |
| Clear the Code and Test Drive | After repairs, clear the code using an OBD-II scanner and take the vehicle for a test drive to ensure the issue is resolved. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | Re-scan the system to ensure the P0967 code does not reappear after the test drive. | OBD-II Scanner |
