P0140 cel
I have a 97 boxster base 2.5 and I just got a p0140 cel indicating oxygen sensor after catalytic converter(cylinders 1-3) interruption of signal. I recently replaced my clutch, coolant overflow, and added a topspeed exhaust. From what I have read on the forums that code typically refers to a bad connection not a bad oxygen sensor. What is the proper method for testing an oxygen sensor and related wiring? Which side of the car are cylinders 1-3?
