How to change cam shaft sensor on 1998 saturn sl1

sc1 means saturn coupe with a single overhead cam engine sl1 means saturn sedan with a single overhead cam engine same engine and same parts for both these cars

replace the crank shaft position sensor it is on the block just above the starter and is held in with a bolt you need a 10mm socket to change it

1. Start the car and let it run until it reaches operating temperture.
2. Feel the top radiator hose. If the engine is warm, but the top radiator hose is not, the thermostat is stuck closed. Replace it. (be sure to ask for a thermostat housing gasket when purchasing thermostat).
3. If this does not correct the problem:
a. replace both the air and fuel filter b. add one bottle of Sea Foam Fuel Additive (auto parts store will have it) to full tank of fresh gas (add before fueling).
It is also a good idea to perform a routine tune-up which inlcudes the above as well as:
1. spark plugs and spark plug wires 2. distributor cap and rotor (if equipped) (otherwise you'll have coil packs) 3. change both transmission fluid and oil (with filters and gaskets) 4. air filter and fuel filter
If the problem persists, have a diagnostics test performed by a techinician and consider the following repairs/replacement:
1. MAS - mass airflow sensor 2. crank shaft sensor 3. cam shaft sensor 4. O2 Sensor(s)

Please let me know if you need further assistance.

if it is an SL1 it has a SOHC 1.9L. Basically the same engine was in all saturns 91-99, just different heads. the Sl2 had double over head cam and the Sl1 had SOHC.

replace it before you end up spending more than you want to $$$$,regee

I recommend buying a Haynes manual (about $20) from automotive store; you'll need it for this task

Check the cam/crank sensors. Also, if the car happens to have a distributor, make sure it is not 180 degrees off. If this does not help, then do a compression check. Remember, and engine only needs three things to run. Fuel, Spark, and Compression. (in order of course.) The firing order for your engine is 1,4,3,2.

Try pulling the engine coolant temp sensor, They often crack not sure why but the ceramic tip cracks makes the car hard to start, or won't start, the car's idle may race while shifting gears, and often smokes. The sensor is on the right side of the engine when looking at it on the head. Easy to change and get too

Change the cam positioning sensor,not the crank sensor,
