Hello Roberto,

Welcome to the forum, ... The code you are quoting is; P0340 CAMSHAFT POSITION SENSOR CIRCUIT MALFUNCTION

You need to test if the Distributor is putting out a signal and test if the crank sensor is putting out a signal. Do this with a DVOM set on AC voltage low setting.

Welcome to the forum, Roberto_OSEGUEDA ! :coffee

Check out Testing CMP sensor.

May want to look at www.obd-codes.com/p0340 also, for further suggestions, like the crankshaft position sensor which won't work if the oil pan has a cork gasket.
