My automatic 98 honda civic Engine light recently came on and I had it check out. The Engine Code read PO700-Transmission Control System (Mil Request) and PO715-Turbine/Input Shaft Speed Sensor Circuit. Recently my car have been experiencing acceleration hesitation. Anyways does anyone have any on how to repair these Engine code problem. Exactly where is the input shaft speed sensor or what other parts do I need to replace? Any help is would be appreciated.

Thanks,

 

probably need to replace torque converter

p0715 is usually an electrical issue.

Check the connector pins on the mainshaft speed sensor, i've seen a couple that were corroded.

The sensor itself should measure in the 400-600 ohm range.

 

Update on current situation. Went and bought the main shaft speed sensor and linear selenoid. Flush out the transmission fluid and fill in new ones. As a result, the car had more power once the car is in motion. Even the Engine light went out also. Then everything changed. The next day, engine light came back on with the same engine code problem and the car start experiencing the same hesitation during acceleration. As of now, the car also rolls back on hills eventhough the car is still on drive. Could it be that my auto transmission is screw or is it electrical problem? Need help!
