P0755

NOTE: Check the shift solenoid valve No. 1 when DTC PO75O is output and check shift solenoid valve No.2 when DTC P0755 is output.

SYSTEM DESCRIPTION
The Engine Control Module (ECM) uses signals from the NCO 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.
