Where is an Oldsmobile intrigue 1999 ignition sensor?

The 1999 Oldsmobile Intrigue's crankshaft position sensor (CKP sensor), which is often what people mean when they say "ignition sensor" (though it's not technically the ignition *switch*), is located on the transmission bellhousing, near the crankshaft. It's generally considered part of the transmission assembly.

It's important to note that the Intrigue also has a camshaft position sensor (CMP sensor). This is usually located on the top of the engine, near the camshaft.

To be certain of its exact location, you should consult a repair manual specific to your 1999 Oldsmobile Intrigue. A Chilton's or Haynes manual would be a good resource with diagrams. A mechanic or parts store employee can also help with this information. Giving them your Vehicle Identification Number (VIN) will ensure they provide the correct information.
