Description:

  • The fault code indicates an open circuit in the control circuit of pressure control solenoid 'B'. This solenoid is responsible for regulating the hydraulic pressure within the transmission. An open circuit can prevent the solenoid from receiving the necessary control signals, leading to improper transmission fluid pressure control.

Possible Symptoms:

  • Check Engine Light illuminated

  • Erratic or harsh shifting of the transmission

  • Transmission slipping or poor acceleration

  • Reduced fuel efficiency

  • Transmission stuck in a particular gear

Possible Causes:

  • Faulty pressure control solenoid 'B'

  • Open circuit in the control wiring for the solenoid

  • Loose or corroded electrical connectors in the solenoid circuit

  • Damaged or broken wires in the solenoid circuit

  • Malfunctioning transmission control module (TCM)

  • Possible

Related Parts:

  • Pressure Control Solenoid: This solenoid regulates the oil flow in the transmission. Problems with this solenoid lead to engine misfire, poor fuel economy, poor acceleration

Possible Solutions:

  • Inspect and test the pressure control solenoid 'B' for proper operation, and replace it if necessary

  • Check the control wiring for any open circuits, and repair or replace as needed

  • Ensure the electrical connectors in the solenoid circuit are securely connected and free from corrosion

  • Inspect the wiring harness for any damaged or broken wires, and repair as necessary

  • Test the transmission control module (TCM) for any faults or errors, and reprogram or replace if required
