If the oil light on your Scion tC turns on, you have to be concerned. It means a potential failure that could damage your Scion tC or even put you in danger so be careful and very reactive.
In this article, we wish to try to provide you with an answer so that you can know the ins and outs of this sight and thus correct the situation.


What does the oil sight glass look like on your Scion tC?

First of all, it is important to find this indicator on your Scion tC. It is red in colour and shows a small burette with a drop on the right. Like all red lights, this suggests that that you must stop your Scion tC as soon as possible. To ensure it works, you will see it turn on when you turn the ignition. If it does not light up, your indicator light is flawed.
Do not confuse this light with the nearly identical yellow one. This one signifies that you are probably short of oil.

What is the purpose of the oil indicator light that lights up on your Scion tC?

Now, let us explain to you what it is for and why it is vital. As opposed to what we may think, it has nothing to do with the oil level in your Scion tC. In addition, it is there to report a loss of pressure in this engine oil, which can rather quickly damage or even ruin your Scion tC’s engine. That’s why as soon as it appears on your vehicle, you must stop the car.
then, we will explain to you what this oil is used for in your Scion tC’s engine. It works with a set of metal parts, which are regularly in contact and therefore wear out. The oil under pressure therefore ensures the lubrication of these parts to stop them from being damaged. Otherwise, it also serves to cool them down due to the fact that they heat up quickly when you drive your Scion tC. Finally, the oil also cleans and circulates dirt that may well affect your engine.
You must therefore ensure that the engine oil pressure is always maintained at its recommended level for your Scion tC. This represents 1 bar at standstill and about 5 bars at high speed. In a logical way, when the pressure does not reach 1 bar, a sensor should indicate it by lighting the warning light that should alert you.

Faults that trigger the ignition of the oil sight glass on your Scion tC:

Three factors could trigger the ignition of this light. First, the most likely, if the oil pump is faulty. It no longer fulfils its function of maintaining oil pressure in the engine. If this is the case, we recommend that you go to a garage because only a professional can make an appropriate diagnosis on your Scion tC.
Secondly, if you run out of oil, the pressure could drop. Same impact with low pressure, the red LED lights up. So what you have to do is put more oil. The last, rarer case is a damaged pressure sensor that can no longer detect the pressure correctly and therefore sends incorrect information. In this case, it is also imperative to call upon a professional for your Scion tC as he will have the pressure control device and will be qualified to tell you exactly what it is.

Conclusion :

So now you know what this light is for and what the related failures are on your Scion tC. Once again, be extremely cautious when a red light comes on as they represent a real immediate danger to your Scion tC and especially to passengers.
