Code U1466 Description
The U1466 code indicates that an implausible driver shift request signal was received on the DPT (Diagnostic Powertrain) Controller Area Network (CAN) bus. This essentially means that the vehicle's computer system has detected a discrepancy or error in the signal related to the driver's shift request. The DPT CAN is responsible for communication between various components in the vehicle's powertrain system, including the transmission control module. An issue with this signal can lead to incorrect shifting of gears, which can affect the vehicle's performance and efficiency.
Common Causes of U1466
- Faulty shift solenoids
- Wiring or connection issues in the DPT CAN bus
- Malfunctioning transmission control module
- Low transmission fluid level
- Software glitch in the vehicle's computer system
Symptoms of U1466
- Harsh or delayed shifting of gears
- Transmission slipping
- Inability to shift gears
- Illumination of the Check Engine Light
- Reduced fuel efficiency
How to Fix U1466
- Diagnose the specific cause of the issue using a scan tool to read the DPT CAN data and identify the source of the error.
- Inspect and test the shift solenoids for proper operation and replace any faulty solenoids.
- Check the wiring and connections in the DPT CAN bus for any damage or corrosion, repairing or replacing as needed.
- Verify the transmission fluid level and condition, topping up or performing a fluid flush if necessary.
- Update the vehicle's software or reprogram the transmission control module to address any software-related issues.
Cost to Fix U1466
