Oldsmobile Aurora- How To Replace Crank Sensor

• Comments ⇓

Problem with my Oldsmobile Aurora. Check Engine codes: P0285, P0410. New (used) computer CPU and new mass air flow sensor. Question: Car is still stalling when stopped. Would like to know where the Crankshaft position sensor is located and if its possible to repair without much experience. I can do a little car repair.

I read some other threads for the Cadillacs and people were saying it wasn't that difficult. Also, is this the reason it's stalling. Any help would be appreciated!! Thanks again.

ANSWER:

Code p0285 does not come up in my list of codes. It is P0385? P0410 is a problem in the secondary injection system. Possibly a bad A.I.R. Pump and blown fuse, other common problems. One of the check valves could be stuck. This is common on Olds Aurora. There is a valve on each exhaut manifold. When they stick or fail, it wwill give this P0410 code.

A crank sensor can cause staling, but usually hard starting. They are located in the center front of the engine block as viewed from under the car. You probably have code P0385. If you are going to replace it (them) you would also have to have a crank sensor relearn procedure done wwith a scan tool.

They are a little tough to get to, even with a swivel socket. They are right next to the oil filter and oil pressure sender. Lay under the front of the car and you will see them.

Problem with my 97 Olds Aurora. New bulb and checked fuses-good. New bulbs fuses are good. Reverse lights don't work! Has new bulbs and fuses are good. Where is the switch or sensor on the trans??

Answer: The back-up lights circuit is internal to the park / neutral switch. The switch is located on the top-rear of the transmission. From under the hood on the passenger side, it is below the brake master cylinder, on the top of the transmmission. Adjustement wwould be needed after replacement. Put the car in reverse and adjust it until the backup lights come on, then tighten dowwn the bolt that is in the slotted hole..
