There are some checks you can do on the sensors, but that won't tell you where to begin. You really should have your codes read so that you know what your car is telling you is wrong. This is one of the best diagnosing tools you have, and it's right there on your car. What kind of problems are you having? There is no way to erase the codes without the scanner though.

What is a scan tool


A scan tool allows for the OBD II (On Board Diagnostics) codes to be read from the engine computer in a car. These are common electronic diagnostics tools used by automotive technicians. They are usually used when a check engine light comes on to determine the error codes associated with the check engine light.


They almost always connect via a standard plug on the divers side under the dash.


Most automotive parts supplier will check a car with complementary service to determine the codes stored in a customers automobile.

OBD will not pass on saturn.It tells me I need a camshaft position sencer.My garage doesnt want to mess with it.Where is this item located and is it an easy replaced piece?


The 4 cylinder engine in your 1996 Saturn SL doesn't use a cam sensor. I know, then how could there be a code for the cam sensor? Well, The electronic ignition (EI) module supplies a signal to the PCM whenever it determines that the #4 cylinder fired on its compression stroke.

You should start by checking to make sure your spark plug wire terminals on the ignition coils are not corroded. Using a multimeter, check the resistance and continuity of each ignition wire. If your car is misfiring, replace your spark plug wires and have the code cleared at your local AutoZone or Advance Auto, unless you have a code scanner.

If the code comes back, most likely you have a bad crankshaft position sensor throwing the code. While the engine is running there should be a +5 volts on the crank sensor everytime the magnetic pickup reads the crankshaft. Using a multimeter you can check the voltage to see if the sensor is functioning properly.

Emissison control light is on and stays on. I has stayed on for nearly 10months now.


If the service engine soon light goes on and stays on there is a hard code stored on the vehicle's computer. Have it scanned to determine what may be wrong with the car's emission control system or sensor on the engine.

All vehicles since 1996 must be OBD-II compliant, and you must find a technician that has the appropriate software on his scanner to be able to scan the computer correctly. The Dealership would probably be a good place to have this done, although some scanners go up to the year 2005 without a problem (like the scanner from Walmart which goes from 1996 to 2005 for most cars for about $98 plus tax).

I have a 96 mazda b4000 and the check engine light is on how can you clear the code without using a scanner?


In obd-II vehicles, you can clear the code by having 40 or more cycles of start and run conditions followed by turning off the ignition completely without having an engine anomoly or issue.

It's easier to use the clear codes button on the obd-II scanner.

Nowadays, you can buy an OBD-II scanner for less than $100 at Walmart. I just got one.

Good luck on this.
