DTC Advanced Diagnostics: P0807, P0808
DTC P0807 : Two-Way Clutch Actuator Valve Stroke Sensor A Circuit Low DTC P0808 : Two-Way Clutch Actuator Valve Stroke Sensor A Circuit High
General Description
The transmission control module (TCM) judges the two-way clutch position by the output voltage from the two-way clutch actuator valve stroke sensor. The TCM monitors the two-way clutch actuator valve stroke sensor output voltage, and when the output voltage is a specified value for a specified duration, the TCM detects a malfunction and stores a DTC.

[ ]: HDS Parameter
Malfunction Threshold
DTC: P0807
The two-way clutch actuator valve stroke sensor A output voltage is less than 0.094 V for at least 0.9 second.
DTC: P0808
The two-way clutch actuator valve stroke sensor A output voltage is more than 4.91 V for at least 0.9 second.
Possible Cause
- Solenoid wire harness failure
- Valve body assembly failure (two-way clutch actuator valve stroke sensor)
- TCM internal circuit failure
Confirmation Procedure
Operating Condition
Turn the vehicle to the ON mode, and wait for at least 5 seconds.
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, the MIL comes on, the shift position indicator blinks, and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the TCM memory.
Conditions for clearing the DTC
The shift position indicator comes off by turning the vehicle to the OFF (LOCK) mode. The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool clear command.
