My engine shut off on me and when I got it back on the check engine light was on and the code was P0715 (Input Turbine Speed Sensor Malfunction). My mechanic said it may be the Input Speed Sensor. Is this something I can change out myself? I called dealer and sensor is only $79 bucks but is it difficult to replace? Could someone please advise because I have to travel on Business Sunday night with my Car and I can't risk it going out on me during that time. So If I can replace it myself this weekend I will.

Thanks,
RJ
