When the car warms up the light will blink on and off as the rpm change, off when higher rpm's. Oil is full, car had been sitting for a week, milaged 122k. When the car is up to full normal temp. light will stay on most of the time.....is the oil pump failure common, just old age, or sending unit ? Where is the sending unit located ?
The oil light on my 001 Toyota Corolla comes on when engine warms up?
