MODERATEHydraulic Oil Temperature Sensor Circuit High Input
What this code means
Hydraulic Oil Temperature Sensor Circuit High Input. The last transmission-related series, including gear selection controls. Like the previous one, it belongs in a workshop rather than a roadside fix.
How to read this code
- PPowertrain
- 0standardised code
- 9Transmission and controls
- 40P0940
The letter P names the system: Powertrain. The digit 0 that follows marks a standardised code, shared by all manufacturers code. The next digit, 9, locates the fault: transmission and controls.
What to do
Have it checked this week. The car remains usable, but the fault will not clear itself and will fail the roadworthiness test.
Clearing a code switches the light off but repairs nothing: if the fault remains, the code comes back.
