To test a 1995 Cavalier crank sensor you would need to get a mechanic's computer. They can put a sensor/fuse tester on it and see if it is working properly.
how to test crank sensor
that would come up on your on board computer, test it with a obd2 scanner an trouble codes will come up, if your car still runs they will test it free at auto-zone or murrays
1991 to 1993 3000gt do not have a crank sensor. Only a cam sensor. And when does go out the car will not start or have a very irregular idle.
A computer diagnostic test will generally tell you if you have a faulty crankshaft position sensor.
Using a scanner with a scope, you can view the output wave of the sensor as you crank the engine.
scanning for codes will indicate if the CPS is at fault.
get an engine diagnostic check from a trusted auto shop. check fuel injectors, and, if equipped, iac motor and tps sensor. Run a compression test.
The most simply way to check a crank sensor in any car is to get in car, turn key to start and watch tachometer (rpm gauge) if it shows rpms the sensor is good. If there is no tachometer then you will be in for checking wires. there should b a wire with 5 volts going into the sensor and with a test light if your lucky probe another and it should light up as the motor turns.
You will have to test the resistance on it to make sure it is within specs.
check it for resistance and compare to stock (oem) specifications. if it's a noise "related" problem the signal can be seen on a oscillascope.
On a 1996 Toyota Rav 4, the crank positioning sensor is located under the hood. It is a thin, black cord that will be located near the lower front engine. In order to test the sensor to ensure it is working correctly you can take it to one of your local auto stores. A few of the stores names are as follows: Advance Auto, Pep Boys, and Jiffy lube. This would be your best and safest bet to have the sensor tested.
check the crank and or cam sensor, the problem was the crankshaft sensor
