The OBD2 code P0953 indicates an issue with the auto shift manual control circuit, specifically showing a high signal reading. This code is associated with vehicles that feature Autostick shifting, which allows drivers to manually select gears while driving.
What Does the P0953 Code Mean?
The P0953 code is triggered when the Powertrain Control Module (PCM) detects a high voltage condition in the auto shift manual control circuit. This typically affects the Autostick feature, which allows the driver to manually control gear shifts.
What Causes the P0953 Code?
There are several potential causes for the P0953 code, including:
- Autostick shift switch failure
- Powertrain Control Module (PCM) failure
- Wiring issues in the control circuit
What Are the Symptoms of the P0953 Code?
Common symptoms associated with the P0953 code include:
- Disabled Autostick shifting functionality
- Unusual transmission behavior (e.g., erratic shifting)
- Potential illumination of the check engine light
How Serious Is the P0953 Code?
The P0953 code is considered urgent. It indicates a significant malfunction that could lead to severe damage to the vehicle or pose safety risks to the driver and passengers. Immediate attention is recommended.
