Do you mean the Crank Position Sensor (also called a CKP)? On 3.5L it is on the side of the block between the firewall and engine (backside if you are looking from the front of the engine). You can get to it from under the car by first loosening the starter from the transmission and dropping it out of the way. The sensor is held on by a single small bolt that you can get at with a flat wrench. I don't know if the 3.8L is similar. The 3.8 wasn't used after the 1999 model year.
on the cilynder head besides the engine
It's down behind the starter.
If you haven't checked for a diagnostic code you're running the risk of wasting your money.
On the air intake filter box
On the 99 Olds Intrigue, the camshaft sensor is located on the rear of the engine. It is just above the starter.
To relearn the crank position sensor on a 2000 Olds Intrigue, you typically need to use an OBD-II scanner capable of resetting the engine control module (ECM). Start by disconnecting the battery for a few minutes to reset the ECM, then reconnect it. After that, allow the engine to idle until it reaches operating temperature and then drive the vehicle under various conditions to help the ECM recalibrate and relearn the crankshaft position sensor data. Always refer to the service manual for specific procedures and requirements.
The camshaft sensor on the 99 Olds Intrigue is located on the engine block. It is under the starter, which has to be removed to locate the camshaft sensor.
I have a 1998 olds Intrigue and mine started doing that it was the crank shaft position sensor
there is none. the speed sensor is in the tranny
the crank sensor is behind the harmonic balancer
Yes........ depending how bad and where. front hard.... more than likely.
You have to drop the starter on the front bottom driver side of the engine... next to the transmission. The crank sensor is about in the middle of the block. One bolt holds it in.
