Engine Control System

DTC P0755 VEHICLE SPEED "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
Check shift solenoid valve No.2 when DTC P0755 is output.
