DTC P0750, P0755
SYSTEM DESCRIPTION
The ECM uses signals from the vehicle speed sensor and crankshaft position 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, valve body or automatic transaxle (clutch, brake or gear etc.).
DTC No.
During normal driving, the gear required by the ECM does not
