What does it mean when your tire light stays on?
When the TPMS light comes on – and stays on – at least one of your tires is at a low pressure level. Check the pressure of all of the tires with a gauge and determine the cause of pressure loss and add air or service the tire(s) as appropriate.
Why does my ignition warning light keep coming on?
One possibility is that the warning light wire is being earthed somewhere along its length. Check this by turning on the ignition and disconnecting the warning light wire. If the warning light stays on, the wire is earthing somewhere. Inspect the wire for any chafing against the bodywork and repair it with insulating tape.
Why is the oil pressure light on my dashboard?
There are actually two scenarios when the oil pressure light is on your dashboard. One of them is that it is a false alarm and there is a problem with the oil pressure sensor or the wirings to it. The other scenario is that your engine actually has low oil pressure, which is a little bit more serious.
Why does my ignition light flicker at low speeds?
But the light does behave in slightly different ways depending on the type of generator fitted to your car. If your car is equipped with a dynamo it is normal for the light to flicker at idling speeds as this type of generator produces little or no current at low engine speeds. The light should extinguish when the engine speed is raised.
How does the warning light on an alternator work?
If the alternator has an external regulator, the warning light wire attaches to it in the same way as a dynamo. Again the terminal will be marked WL or IND. Some cars, however, have an alternator which uses a separate relay for the warning light circuit. In this case you should disconnect the wire from this relay.
When does the ignition warning light not come on?
If your car is fitted with an alternator the warning light should not come on when the engine is idling, provided the idle setting is correct, because an alternator produces current even at low speeds.
Why is the oil pressure warning light still on?
If you have refilled your engine oil with a new one but the light is still on, the culprit could be the engine pressure sensor. The sensor is connected through a circuit from the engine to the dashboard. With time the sensors get filled with dirt and this reduces their ability to detect low oil pressure effectively.
