When am stopped at red lights the oil light flickers. Its stops as soon the car starts moving again. What could this be? I the oil is full and recently changed. its a toyota echo 2001 automatic. Just bought the car yesterday
my 2001 echo does the same thing. 37000 miles on it and i just bought the car. My mechanic changed the oil pressure switch; didnt work. Took it to toyota service to diagnose; they said it was the oil pump and for 1600 they would fix it. My mechanic did it for 400 but it still didn't fix the problem. No seems to know what the problem is. The oil pressure seems to be fine at higher revs but it drops to 4 psi when idle which i guess is why the light flickers. My mechanic still has the car trying to figure out the problem. Ive only had the car for less than a month and drove it less than a week. :( idkmy 2001 echo does the same thing. 37000 miles on it and i just bought the car.

You really need to check it with a oil pressure gauge. It would be a good idea to change the part again,it could be at fault even though it is new,cause it is having a different symptom .
Your motor is getting Tired or your Oil Pump is going bad.
Dodge has a problem with their motors and their Oil Passages get GUNKED really bad. This is what you should do,...
A. Get 1.5 Quarts of Diesel Fuel and drive to where you have your Oil changed
B. Add the Diesel Fuel to the Oil and let it IDLE (don't Drive the car under operating conditions). Let it Idle for 15-20 minutes and then have your Oil Changed
C. Have them use 20W-50 Oil, this is going to raise your oil Pressure and the light will not come on anymore.
Reason... Metal parts are wearing and that is oil gets into the system to lube the bearings. Pump Screen may be clogged and this will dissolve the Carbon Build up.
The light means the oil pressure has dropped below 10psi. You could replace the oil pressure switch and see if the light stays off, or have the pressure checked with a mechanical gauge. Make sure the engine oil level is full.
Your oil pump is loosing power, this light is going on when you have driven for long periods or in high temperature, the hot oil looses viscosity and gets thinner, try changing the oil with a high mile one (cars/trucks with more than 100,000mi) or add an oil pressure restorer treatment, this will do the job for a while but your truck "has warned you already" it will need a new oil pump soon. Good luck
Sounds like a problem with a weak sensor and the computer. You need to
get your mechanic to code the car as to rule out any problems with the
computer or the sensors. Your car is about the right year for those
sensors to start getting weak. When the computer reads those sensors
that then sets things. So if the sensor is getting weak, it would not
be reading things right so your car would be not running so good. I
would be looking at the Throttle Position Sensor. If after coding the
car and nothing show up there. I would be checking for a vacuum leak
they will often cause this problem. And one more thing when is the last
time you did a good tune up on the car? Stark plugs, wires, distributor
cap and rotor? Air filter might be something to look into too. I hope
this helps and good luck!
