When I leave for work in the morning, oil light stays off for 7 to 8 miles then comes on while in a no throttle situation. If idle is increased, light will dim and go out.
If the sending unit is working correctly, I would say the oil pump or engine is failing.
You can replace the sending unit or have the oil pressure checked with a mechanical gauge to verify.
Its also possible the engine oil is being diluted by gasoline or other liquids.
Thanks Stephen. I finally found the oil pressure specs for my engine. this engine idles with 4-6psi when warm. I bought a mechanical gauge and a new sender. when hot I was getting 15psi I installed the new sending unit and road tested with no problems. I guess I was overthinking the problem. Again thanks.

The fuel pump is located in the fuel tank. The fuel tank is in the rear of the car. Yes you have to drop the tank but this is simple and straight forward. First disconnect the neg bat cable. 2 locate the drain plug on the bottom of the tank, be sure that you have enough empty gas cans to hold the fuel.Get a freind and 2 drain pans that will slide under the tank.3 unscrew the plug and drain useing the pans alternately, heres where your pal comes in.Slide the full pan to your pal to empty while you fill the next.When done you can start with the nuts and bolts of the thing. You dont have to remove the tail pipe but it makes it easier and
unless your car has spent its life in a rust belt and all the fasteners are corroded faster. The hardest part is probibly going to be the fuel filler tube and acciated lines.before going any further remove the rear seat bottom cushin.Under it you will find a screwed down panel.Take the panel off and diconnect the elect connectors.
you will find two straps holdin the tank in place. Find the bolts and remove them. the tank should now come out. In the top center is the pump. Use a brass drift punch remove the retaining ring and lift out the pump. Reassymble in reverse order. 2 things to concider, if you raise the car make sure to use jack stands. I also found that dialectric grease eases the installation of rubber hoses .

these cars have problems with bad oil pressure warning switches you may have someone put an oil pressure gauge on the car and make sure your pressure is within spec and go ahead and change the sender if it checks out please rate -jeff

Clean the IAC. Disconnect throttle body air hose and you will see a hole on the bottom of the throttle body just before the butterfly valve. Spray throttle body cleaner down the IAC hole and then let it soak about 1/2 hour. Reconnect hose and run engine about a minute and then repeat this process 2 or more times. Toyota engines from 1997-2005 commonly have the IAC get cruded up with carbon as early as 35,000 miles. This is a sImple and cheap repair that many repair shops don't want you to know.

Hello.
Do you have a full-size spare tire? If so, it too is checked via the Tire Pressure Warning System. Perhaps it is low, this is quite commonly omitted when setting tire pressures. If you have a temporary spare tire, it is not checked. If you have no full-size spare, one of the TWPS sensors may have been damaged by your tire changer. This can happen very easily, if the changer is not careful whilst dis-mounting the tires. A Toyota dealership has a special service tool that will check each of the sensors for output, while on the car. If a sensor is found to be bad, the tester will find it.
