Question about Saturn Vue
Testing Crankshaft sensor:
Pull up the RPM reading and crank the engine over. Hold accelerator to floor to shut off fuel to the engine. No reading find the crank sensor, inspect for damage, unplug electrical connector and clean it with electrcial contact cleaner spray and then plug the connector back into the sensor. Crank the engine while watching for RPM reading, again hold down the accelerator to prevent fuel flow to the engine. If you have RPM reading now sensor is ok, engine should run.
Do a continuity test on the crank sensor, if it reads zero, it is bad.
