I have read the P0715 code (Turbine/Input Shaft Speed Sensor Circuit) on my girlfriend's 2003 ZX2. I have noticed that there are a couple of threads on this forum regarding replacing the TSS. However, I am unable to find the part number. My search has led me to "F32Z 7F040 A", but I am not sure whether this is correct. Ford's parts website shows this as "WIRE ASY - TACHOGRAPH" at $152. Is this correct? Are there cheaper alternatives available?
EDIT: Tutorial added
I went to Ford and ordered the part. The part number was correct. Here's all of the information you need on what to do in case you get this error code and your TSS has gone bad:
