Hi all:

I got a check engine light a week ago. Checked it out today and it says I have a fault associated with the crankshaft position sensor. I reset the ECU and the CEL shut-off after I restarted the car (but I haven't driven it yet).

Service manual says that the Crankshaft sensor is a device that counts the movement of the teeth of the flywheel, and that it is located on the oil pan.

So if the CEL activates again, I assume I will have to either replace the sensor or the flywheel.

Are the lightened aftermarket flywheels a decent product? I have a 5-speed manual with a recently installed ACT clutch.

If the problem turns out to be just the sensor -- and if I have to take down the oil pan to get to the part -- are there any aftermarket oil pans that are worth installing? I know that some people install "deeper" aftermarket pans to add oil capacity to the engine.

Of course this is all speculation. If my CEL doesn't activate again, I'm not changing anything.

But could I end up with some kind of catastrophic failure of the engine if the crankshaft sensor goes completely dead? I am fairly certain that all the ignition timing is dependant on the crankshaft sensor.

 

Dont get too ahead of yourself. Its most probably the sensor itself.

There are 2 sensors. One is near the crankshaft Pulley, the other is on the other side of the engine. The most common one to go bad is the one under the pulley.

your service manual will tell you which code is for which sensor.

I really really really really really doubt its your flywheel.

Sensor costs like 60 bucks. Good luck.

 

since you just recently got your clutch replaced, check and see if the sensor is plugged in tight. when you take down the trans to get to the clutch you have to remove the crank sensor, that is the on right in front on the fly wheel. and the other sensor you dont need to take anything down, just turn your right front wheel all the way out and you will be able to see it. but i figure thats not the one since you just got your clutch replaced.
