Suspect Camshaft position sensor

Hi,
Please I need help, I have a 1992 Eclpise 1.8l. Car has always ran fairly well, not a power house, but lately it has lost a huge amount of power and motors pings on accerlation. Changed out gas filter,air filter,plugs and wires, rotor and cap,had catalytic converter checked- OK and ran a compression check-OK. Finally today the cel came on and when I downloaded the code it was a Crankshaft camshaft position sensor along with an intake temp fault. My mechanic told me the car would not start or run with these faults present true?
Is this a big deal to replace? Where is the componet located? A dealer item? What manual would guide me through this procedure(other than a service factory) Car has 135000 miles.
Thanks in advance,
Michael

Is it the crank or cam shaft sensor? Your thread starter says camshaft, but your thread says crank.
As far as the intake temprature fault code. You can replace that yourself.

It's the camshaft sensor that I suspect to be the problem, is it part of the distributor assembly? Do you have to change the distributor to fix the problem?

did that light come on after the compression test? you have to disconnect that sensor to kill spark/fuel during a compression test and any time you do that it will throw a CEL. Try reseting your ecu and see if it clears. If it comes back on, then you have a problem.
