P0750
DTC PO75O / P0755 SHIFT SOLENOID A / B MALFUNCTION(SHIFT SOLENOID VALVE NO.1 / NO.2)
SYSTEM DESCRIPTION
The ECM uses signals from the NC2 revolution sensor and vehicle speed sensor to detect the actual gear position (1st, 2nd, 3rd or O/D gear).
Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical trouble of the shift solenoid valves and valve body.
DETECTING CONDITION
NOTE:
- Check shift solenoid valve No.1 when DTC P075O is output.
- Check shift solenoid valve No.2 when DTC PO755 is output.
