OIL LIGHT I have a 2001 Sable. The car runs fine ( no indicators) but when I finish driving and put the car in park, the oil light flashes in bursts. I check the oil level and it is fine.

1. Turn the ignition to run (one position before starting engine).
2. Use a paperclip to push and hold the RESET button for 5 seconds. The CHANGE OIL SOON indicator flashes to indicate the system is reset.
3. Turn the ignition off and start the engine to verify the indicator has been reset.

1991 BUICK Park Avenue Maintenance Light ... - Oil Reset

To find out if it's oil get a oil leak detection kit. The kit contains a dye, light and glasses. Simply put the dye in oil fill location run and drive vehicle. Park vehicle shine light on new marks if they glow you have a oil leak if not it could be transmission fluid

could be a problem oil pressure sender or sensor following the flush
check first using a mechanical gauge to check oil pressure and then replace the faulty unit

Oil light blinking usually indicated low oil pressure / viscosity. Probably either low on oil, incorrect oil weight, poor quality oil, or needs oil changed..........Mike

The following procedure will reset your oil change light. Thank you for using Fixya!

2008-2010 Sable

1. Turn the ignition to run (one position before starting engine).
2. Press and release SETUP to display "OIL LIFE XXX% HOLD RESET = NEW".
3. Press and hold RESET for 2 seconds and release to reset the oil life to 100%.
4. Turn the ignition off and then start the engine to verify the indicator has been reset.

This Indicates POOR OIL PRESSURE and PROBABLE OIL PUMP FAILURE, DO NOT DRIVE Before Correcting FIRST Have the Pressure Checked MANUALY IF OK SENSOR is BAD IF PRESSURE is NOT OK OIL PUMP has FAILED and Requires Replacment.

Yes, the sensor is in small housing the goes in the hole where the distributor used to go. That also drives the oil pump so don't drive it you'll ruin the engine. It's located down under the throttle body, near transmission end of the engine.

It's very possible a coincidence and that the flashing oil light is the oil pressure switch. I'd check it out immediately to make sure there's sufficient oil flowing through the engine. Merely jump starting the car shouldn't have knocked anything loose so to be on the safe side, assume there's an oil pressure issue. You were right to not use the car in the interim.

Your transmission torque converter lock up clutch is not unlocking, that kills the engine and is the cause of the OD light flashing.

This usually indicates that the oil pressure is low, but you need to get it checked out whether it's just a pressure sensor fault or connection issue, or it actually has got low oil pressure. The last one is the most concerning, because it could be causing internal damage if there is not enough oil pressure. Hopefully with a relatively late model car it will just be a sensor issue, but I would get it checked out ASAP, and preferably not use the car in the meantime.
Hope this helps, Mark.
