Hva betyr feilkoden?
The signal to line pressure solenoid STH is too low. The fault is intermittent, so it may have occurred on an earlier occasion without being active right now. The solenoid controls the line pressure in the transmission, so the fault can affect how the gears feel.
Mulige årsaker
- The control signal wire or the signal wire is short-circuited to ground
- Defective STH solenoid
Hva du kan gjøre
- 1The fault is intermittent: clear the fault code and road test the car to see whether it returns
- 2Check the connectors on the control module and on the transmission for contact resistance and oxidation
- 3Have a workshop measure the control signal wire and the signal wire to STH against ground, and replace the solenoid if the wires are intact
Symptomer du kan merke4
- The general orange warning lamp is lit
- The malfunction indicator lamp (MIL) is lit
- No lock-up function
- Gear shifts are harsh
Hva feilen kan påvirke3
- The control module's emergency program (Limp-home) is activated
- Line pressure is not regulated, so it stays at maximum all the time and gear shifts are harsher
- Gear slip times are not adapted when driving at high altitude
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
