1. Check your oil level. If oil level is not ok, correct oil level and find out why oil level was low and correct the problem. (Leaks, bad PCV, Burning oil due to severe engine wear, nobody has bothered to check it for the last 3000 miles, WAY overdue for an oil change, etc.) If oil level is ok, proceed to next step.
2. Remove the oil pressure sensor and install a manual oil pressure gauge. Run engine to verify low oil pressure. If gauge shows that the oil pressure is low, overhaul or replace engine. If oil pressure is ok, replace oil pressure sending unit and retest.

a quick test is to disconnect the sensor connector hook up and ohm meter to the sensor connector on the hub side not the engine side and spin the hub if the resistance rises and falls you're most likely ok if the resistance reads 0 or infinite you have found the bad sensor..this won't always be the case but it's a good start in the right direction

recheck the sensor most likely not properly hook up or attached to clip

Hello! This indicates a fault with the wheel speed sensor/ABS sensor. Any major auto parts retailer can pull the details of this code (which sensor) for free, which will help you identify if the wiring is loose or damaged or if the sensor will need to be replaced. If you need to replace the sensor - you will need to replace the entire wheel bearing assembly, as the sensor is internal.
