P0715 Mitsubishi Code - Input/Turbine Speed Sensor Circuit Malfunction
Quick Answer
The Input Speed Sensor detects the primary pulley revolution speed and sends a signal to the Transmission Control Module (TCM) and Engine Control Module (ECM). Common causes include Faulty Transmission Speed Sensor, Transmission Speed Sensor harness is open or shorted, Transmission Speed Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

10. Will resetting the Check Engine light make OBDII code P0715 disappear in a Mitsubishi?
- Resetting the Check Engine light may temporarily clear the code, but it will likely reappear if the underlying issue causing P0715 is not addressed.
Discuss the causes and fixes for P0715 Mitsubishi OBDII Code
-
I drive an '03 Lancer. Symptoms include spontaneous, hard shifting while driving, or reversing the car (Both ways). I also have the code, obviously.
-
The most common problem that will set the P0715 code is the Input Shaft Speed Sensor, the sensor is on top of the transmission. Unfortunately, I don't have and image and I couldn't find one in the factory service manual either.
-
Thanks. You don't have the drop the transmission, you should be able to access the sensor from the top. Here is the only image I got.

One more thing would that be the transmission or the transaxle of the vehicle that the sensor is on
-
Transaxle and transmission are basic the same. It's called transaxle the transmissions that includes the differential. Most front wheel drive vehicles have transaxle.
