What does this fault code mean?
The power steering module monitors the pump motor and its own internal temperature. The fault code is set when the signal from the internal temperature sensor shows a temperature that is too high. The cause can be high temperature outside or in the engine bay combined with hard driving, or a hydraulic or mechanical problem in the steering assist.
Possible causes
- High outside temperature or high engine bay temperature, combined with hard driving
- Hydraulic or mechanical problem in the steering assist, such as a blocked steering gear or blocked hoses and pipes
- The electric power steering module (EPS) is damaged
What you can do
- 1Start the engine and read the fault code status
- 2If fault code EPS-0030 is present at the same time, remedy EPS-0030 first
- 3Let the car cool down after hard driving, then read the fault code again to see whether it returns
- 4Check that the power steering does not leak and that hoses and pipes are not pinched or blocked
- 5Power steering affects how easily the car can be steered, so have a workshop fix the fault soon
- 6If the fault code returns with permanent status and no fault is found, have a workshop replace the electric power steering module (EPS)
Symptoms you may notice3
- No or weak power steering assistance
- General warning lamp is lit
- A message appears in the display
