Even though all four tires have the correct tire pressure, the light will stay on
if the pressure in the spare tire is incorrect. This is because of a sensor in the
tires.
The spare tire on a tacoma sometimes has a sensor in it, too.
Check the pressure in all of the tires and inflate them to the pressure indicated on the door jam. The light should go off within a few minutes. If it stays on then you have a bad sensor in the tire or on the car.
Check the pressure in all five tires-spare included. You will have to remove the spare cover, which takes some time if you have a soft cover. Once all the tires are at the same pressure, the light should go out. I did it with the car parked, so it seems driving it for reset is not required. If the pressure is off between the tires after adding air, the light may stay on. They must all be close or the same for the light to go out. Use a real tire gage rather than the one at the gas station air nozzle.
The tires must be inflated to the precise psi for the light to go off. If the tire pressure is too high, the light will stay on. The system should reset itself, after proper inflation, within a few miles of driving.

Check that the oil pressure is correct. The oil sending switch or the wiring for the switch is the most likely cause.
There should be a label on the inside of the drivers door that will give you one option for tire pressures for factory installed tires. If you have replaced the tires and they are not exactly the same as the ones you removed the sidewall of the new tire will give you a range that is acceptable. For longer tire life try and stay within 2-3 lbs of the max pressure.
Oil PRESSURE is an indication of the condition of the engine's bearings. If the oil pressure is low, the engine is about ready to quit.
It can.
you can't.. you should check to see that all tires are at there proper PSI, that your tread is not worn thin, and if you have your spare tire on the light will stay on the entire time the spare tire is on, because the spare tire does not connect to your electrical sensor the way the stock tire does. Same would happen if you have aftermarket rims and tires. So in whole, the light doesn't go off unless your stock tires are on and they are at proper PSI. ( hope this is helpful )
No!It is illegal.The check engine light will always stay on.The engine may actually run worse due to the computer trying to correct oxygen sensor readings and the change in exhaust back pressure.No!It is illegal.The check engine light will always stay on.The engine may actually run worse due to the computer trying to correct oxygen sensor readings and the change in exhaust back pressure.
Low oil pressure or a defective oil pressure sending unit.
