Details of the Toyota p0755 OBD Code
Code P0755 in a Toyota indicates a malfunction in the Shift Solenoid B circuit.
OBD code P0755 for Toyota vehicles indicates a malfunction in the Shift Solenoid B circuit.
This code is triggered by the Engine Control Module (ECM) when it detects an electrical fault in the circuit related to the transmission’s Shift Solenoid B.
The Shift Solenoid B is responsible for controlling the hydraulic pressure to engage/disengage the clutch packs for the second gear in the transmission.
When this solenoid or its circuit has an issue, it can lead to harsh shifting, transmission slipping, or the transmission not shifting at all.
Mechanic’s Tech Notes
Troubleshooting notes for Toyota P0755 focus on the shift solenoid B malfunction in the transmission.
To diagnose and fix OBDII code P0755 in a Toyota, start by checking the transmission control module (TCM) power and ground using a multimeter.
Verify TCM communication over the Controller Area Network (CAN) using a scan tool.
If the TCM does not respond, reprogramming or reflashing may be necessary.
Additionally, inspect the wiring harness and connectors for any damage, and ensure connector pins are not broken, bent, pushed out, or corroded.
Addressing these issues can help resolve the P0755 fault code.
