What it means
The calibration data programmed for pressure control solenoid K does not match the format expected by the transmission controller.
At a glance
- Usually lights the check-engine light
How it works
Pressure control solenoid K controls hydraulic pressure in response to transmission-controller commands. The controller checks whether the calibration data for solenoid K is encoded in a format it can use. This code sets when that data is incompatible with the controller's expected format, potentially affecting shift quality or available gears.
Common causes
Most likely first.
- Replacement solenoid incompatible with software version
- Calibration code format does not match controller version
Symptoms
- Transmission warning light may illuminate
- Harsh or delayed shifting
- Transmission may enter limp mode
How to diagnose it
- Use a scan tool to capture transmission codes and freeze-frame data, including any link to recent solenoid K or controller service.
- Verify that the installed solenoid K and its calibration record match the transmission and controller software version.
- Inspect the solenoid K electrical connector and transmission harness for corrosion, fluid intrusion, loose pins, or damage.
- Check solenoid K calibration status and related controller faults with a transmission-capable scan tool.
- Confirm the controller supports the solenoid K calibration format, then complete any required setup or programming per manufacturer instructions.
Common fixes
- Enter or correct solenoid K calibration data in the format required by the controller.
- Repair or secure the solenoid K connector and wiring if inspection shows a fault.
- Replace a solenoid K that is incompatible with the transmission or controller software.
- Update or reprogram the controller with a compatible manufacturer-approved version if specified.
Can I keep driving?
Avoid towing and hard acceleration while shifts are harsh or delayed. If the transmission limits its gears or shifts unpredictably, stop when safe and arrange recovery because continued driving can increase transmission wear or damage.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
