Could be either a gauge gone bad, or the sending unit. Unplug the oil sending unit with key on to see what the gauge does.

On my 2005 Trailblazer the oil light stays on longer than the rest of the warning lights. Is this a concern?


If you live in a cold climate then oil takes longer to warm up, this may account for the time lag.if you live in a fairly warm place then the oil is getting quite thick and viscotic.This may suggest its time for an oil change including filter.if this has been recently done then it may be the oil pressure switch.also worn engines have lower compression so the oil pressure takes longer to rise.

It depends on litre size of engine? The 5.3 litre has three wires. The 4.2 has two wires.

I hAVE A 2005 CHEV TAHOE THE OIL GAUGE READS 80. I TRIED TURNING ENGIN ON & OFF AND IT STILL READS HIGH. IS THERE A PROBLEM?


If it has a constant reading you might have a bad oil pressure sending unit.Im not really sure where yours is located because there are different locations for different vehicles.Your local auto parts store can give you the exact location for your vehicle.

Oil pressure at 0 on 2005 trailblazer


It sure sounds like the oil sending unit is at fault,now sometimes,not always,the oil sending unit will seep oil or leak oil if they go bad,but like I said,not always,change the unit,and the oil and filter just for precaution.

Where is the sending unit located?


On most GM V6/V8 engines the oil sending unit is on top of the engine near the firewall possibly under/behind the distributor. Look at the extreme rear of the intake manifold. On some others it is mounted near the oil filter. If you have a light it will just be a single wire. If you have a true gauge it may have a very small hose/line connected to it.
