Oil engine is flashing 5 times after starting the engine

check the sensor

The way to reset the oil light on your Trailblazer is.You first turn the key on but do not start the vehicle.Press the gas pedal 3 times all the way to the floor within 5 seconds.The change oil light will flash several time then go out.The oil life has been reset.Remember don`t start the vehicle just key on engine off.Hope this helps.Good luck.

Have you checked the engine oil level? This could be due to low engine oil or just a faulty oil pressure switch. Hope this helped...

check for proper oil level in engine with dipstick if ok.then install mechanical oil pressure gauge on oil pressure sending unit to verify proper oil pressure, if pressure ok. then replace the sending unit/sensor, if pressure not ok. , you may need to remove engine oil pan to check for restriction on oil pick-up tube screen. if ok replace pump. but also check clearance on mains and connecting rods.

most of these models have 2 oil lights.The red one is oil pressure,if flashing or on when engine is running,it is usually serious.check oil level,but usually caused by blocked pickup screen(a common toyota fault) when services aren't done.The orange oil light is tripped by an oil level sensor on the side of the sump when the oil level is low.If the oil level is ok,note this is a common fault especially if oil changes have been missed,and/or a petrol engine oil used and sludge builds up,sometimes using an additive for flushing prior to oil change can help,but may not work on 1st oil change.

Your oil sensor may be faulty, or your may have a leak since you said the fluid level is okay.

i have a 2003 vw beetle turbo. The oil light blinks even after a recent oil change.

Here's how to do it

sometimes when you are going up hill your check engine light or your oil light will come on because all of the oil is at the back of your oil pan.

Try reseting it again. Sometimes it takes a couple of tries to get it right.
