What it means
The control module checks whether brake pressure sensor E has its required calibration data. It sets this code when the calibration is missing.
At a glance
- Usually lights the ABS or stability-control warning light
How it works
Brake pressure sensor E reports hydraulic pressure to the brake control module so it can manage brake assistance and stability functions. The module sets C059E when the calibration data required for sensor E is missing, often after sensor or module work or an incomplete calibration.
Common causes
Most likely first.
- Calibration not performed after sensor or module service
- Calibration procedure incomplete
- Module configuration issue
Symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
How to diagnose it
- Read the ABS module's stored and pending codes and freeze-frame data to see when the calibration fault appeared and whether other brake-system faults are present.
- Check the service history for recent work on brake pressure sensor E or the brake control module that may have left calibration unfinished.
- Inspect sensor E and its connector for a loose fit, damage, or wiring problems that could prevent calibration from completing.
- Use a compatible scan tool to check whether the module reports calibration data for sensor E and follow the vehicle's service procedure to perform the required calibration.
- If calibration will not complete, check module configuration and related fault codes against the manufacturer's service information before considering module repair or replacement.
Common fixes
- Complete the specified calibration for brake pressure sensor E with a compatible scan tool.
- Repair a loose or damaged sensor E connector or wiring that prevents calibration.
- Correct the brake control module configuration if it does not match the vehicle.
- Repair or replace a faulty sensor or module only after the required calibration and configuration checks.
Can I keep driving?
The ABS warning and disabled stability control mean those functions may not be available, and brake assist may be reduced. Drive cautiously only if normal braking feels reliable; avoid high speeds and slippery roads, and stop if braking changes or warning lights indicate a more serious brake fault.
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.
