Oil Light Is On Before Starting The Car -Coolant Problem?

[praneetsrivastav]

Today i noticed low oil light is on. but only when engine is not running. after I start the engine light goes away and car runs fine. no temp spike n all

 

However I did notice very low coolant level which is odd because I had the car service less than a month ago and the coolant would have been topped up.

is that warning related to engine oil which is current half from max point. ?

 

any pointers ?

What colour is the light? Red is pressure, yellow is level

The oil should be half way between low and max because of the up and down the hills.

If is all the way up when you go down the hill you will have your crankshaft flooded and if you have it close to minimum when you go up the hill the oil pump will pull in air.

When you put the ignition on, the oil light and the battery light (and some others) would stay on until the engine is on, when the engine is on it builds up pressure and the sensor will turn the light off( well the ecu but you get my point).

 

How it helps.

Just to clarify the oil light come as soon as your put the key and do one click (no ignition). When you do one more click and start the engine.. all lights come on and eventually turns off except the seat belt

 

should the coolant be disappearing this fast ?I don't see any visible leaks. and car temp is fine as well. (Just below the half mark after 20 mins of drive)

It is abnormal, somewhere is a short as it shouldn't come on, any light for that matter.

Try the key dance( is not always accurate) and see if you have any faults coming up.

alright I gave the wrong information earlier. it was red light not yellow . 

and key dance shows P1130 but i have had this code even when there was no light.

 

i dont notice any problem while driving {no cutting off  or any abnormal behaviour ].

 

 

also noticed no one was able to read code fault from my car . the mechanic actually tried to take it to few other places to read.

but as per him even 15k worth diagnostic system did not read anything off my car.

 

has any faced similar problem?
