When this code is triggered, it typically means that the circuit has detected a low signal, which may disable the manual shifting function.
What Causes the P0957 Code?
Several factors can lead to the P0957 code being set, including:
- Autostick shift switch failure
- Powertrain Control Module (PCM) failure
- Wiring issues within the circuit
These issues can prevent the system from recognizing the manual gear selection, leading to the malfunction.
What Are the Symptoms of the P0957 Code?
The primary symptom associated with the P0957 code is the disabling of the Autostick shifting feature. Drivers may notice that they can no longer manually shift gears, which can impact the driving experience, especially in situations requiring precise control over gear selection.
