Fix P0967: STEP-BY-STEP diagnostic GUIDE!

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

CodeInformation
MeaningP0967: 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.
