Oil Pressure Warning Light
What it means
Shown as an oil can with a falling drop, this light means engine oil pressure has dropped too low to protect the engine. It is normal for it to glow for a few seconds at key-on and go out once the engine runs; if it comes on while driving, stop the engine immediately.
Codes that may appear with it
The most common stored codes that may turn this light on; scan the car with an OBD reader to find the actual code.
Symptoms4
- Red light on or flickering while driving, especially at idle or in corners.
- Metallic ticking or knocking from the engine.
- A message asking you to stop the engine or check the oil.
- Rising engine temperature if driving continues.
Possible causes6
- Very low engine oil level from a leak or oil consumption.
- Old oil or oil of the wrong viscosity.
- Clogged oil filter or oil pump pickup screen.
- Faulty oil pressure sensor or wiring giving a false warning.
- Weak oil pump.
- Worn engine bearings (less common and more serious).
How to diagnose5
- Stop the engine in a safe place, wait a few minutes, then check the oil level on the dipstick.
- If the level is fine, do not restart the engine; have the actual oil pressure measured with a gauge at a workshop.
- Inspect the oil pressure sensor and its connector for leaks or damage.
- Check when the oil was last changed and whether it meets the manufacturer specification.
- If measured pressure is low, the workshop checks the pump, pickup screen and bearings.
How to fix6
- Top up with the recommended oil and fix any leak.
- Change the oil and filter if the oil is old or the wrong type.
- Replace the oil pressure sensor if the gauge test shows normal pressure.
- Clean the pickup screen or replace the oil pump as the tests indicate.
- Repair worn bearings with internal engine work if confirmed.
- Start the engine after the repair and confirm the light goes out within seconds.
Repair cost
In Saudi riyals; the highlighted part is the expected range for this fault.
In the Saudi market: SAR 100–8,000 (≈ USD 27–2,130)
Our prices come from the Saudi market, converted at a fixed rate (SAR 3.75 per USD). Prices in your country may differ a lot, so we show the cost level.
The cost starts with an oil top-up or a cheap sensor, and reaches the upper end if driving with the light on has damaged internal engine parts.
Prices are rough estimates for common cars at independent workshops and vary with the car and the source of the part.

Frequently asked questions
Can I drive to the workshop?
No. Driving without enough oil pressure can destroy the engine within minutes. Stop the engine, and if the light stays on after topping up, call a tow truck.
How is it different from the amber oil level light?
The amber light warns that the level is getting low before it is dangerous; the red light means the pressure itself has dropped, which is far more serious.
Why does it flicker only at idle?
Oil pressure is lowest at idle, so flickering there usually means low oil or a weak pump and needs urgent attention.
