I've been having problems with my car. Took it to the mechanic and was told there is a po725 engine speed sensor circuit malfunction which requires engine speed sensor to be replaced. But my mechanic doesn't know where it is. Where is the engine speed sensor and how much will it cost?

To be honest if the mechanic does not know where it is or the resources to find out where it is, and the proper replacement procedure to insure correct installation, you need another mechanic.
