The oil is probably too light for it at this stage; add an oil additive to it and see if it improves. the additive I'm talking about is commonly known as "honey" and we use it to thicken the mix when the bearings get worn and the oil pump gets weak. if it improves the situation, then your future oil changes have to use thicker oil or start thinking about replacing main and rod bearings as they are the usual suspects when oil pressure drops. I could be wrong and it's just a sensor, but that is very rarely the case. if the sensor shows signs of seepage, replace it and see.

SOURCE: 1997 grand prix gtp. Tire pressure/abs light

Hello! This indicates a fault with the wheel speed sensor/ABS sensor. Any major auto parts retailer can pull the details of this code (which sensor) for free, which will help you identify if the wiring is loose or damaged or if the sensor will need to be replaced. If you need to replace the sensor - you will need to replace the entire wheel bearing assembly, as the sensor is internal.

on my 2000 gtp my low oil dummy light was on due to the wires being cut from the oil pressure sending unit....like an 02 sensor type style plug hanging out of the oil pan....sending unit could be bad also....

2005 grand Prix oil pressure light an dinging comes on

1. Check your oil level. If oil level is not ok, correct oil level and find out why oil level was low and correct the problem. (Leaks, bad PCV, Burning oil due to severe engine wear, nobody has bothered to check it for the last 3000 miles, WAY overdue for an oil change, etc.) If oil level is ok, proceed to next step.

2. Remove the oil pressure sensor and install a manual oil pressure gauge. Run engine to verify low oil pressure. If gauge shows that the oil pressure is low, overhaul or replace engine. If oil pressure is ok, replace oil pressure sending unit and retest.

Low oil pressure light comes on when i stop giving the car gas like when i come to a stop sign or light and every now and again the check engine light comes on. I change the oil to a heavier oil and the...

This may mean engine wear or bad oil pump. I would have the oil pressure tested to see if its a shot some where or if the pressure is really low, this is done by removing the sensor and installing a gauge and driving the car to see if the pressure is low, if the pressure is low then more checking is neede to see why,you may have worn engine bearings or bad oil pump. depending on the mileage it may be smarter to replace the engine, not knowing what internal damage has been done already. good day.

Oil capacity of 2002 grand prix

Right around 4 3/4 quarts. Use an AC Delco filter. There is a difference and this will prevent low oil pressure.

Low oil pressure light on at idle

first check the wire going to the sensor, give it a good clean on the conditions. if this does not sort the problem it could be because of the oil change, muck in the oil could of gotten into the sensor, you maybe able to clean it out but you may need to replace it. when an oil change is done they would put a cleaning agent in with the oil, this loosens any burnt oil off the engine, this burnt parts can stay in the engine and float around and even block the pressure sensor.

'92 GMC PU has low oil pressure

With that kind of maintenace pump and bearings should be ok,the oil pressure sending units get weak on these models I have replaced alot of these for this same condition.The check engine light reads its voltage from the sensor.

Low iol pressure light coming on

could be a sensor. Need to put a gauge on there and check the oil pressure, If ok, replace the sensor. If you have low oil pressure at idle, it is likely the oil pump is shot or the pick up screen is clogged with debris. In either case, this is going to require major repairs.

Burning oil, but dont know why

Nowdays 1 Qt. in 3000 miles, really isn't that bad, even some new vehicles claim that's normal. I know with my current vehicles, both at approx. 150,000-160,000 miles, they won't use any for first while after an oil change, but then after mileage starts adding up again, they start to use a little, approx.I Qt, every 1000 miles or so, until it's changed again. I've switched to the high mileage oil, just for piece of mind, as they say it revives seals, and has added protection for the higher mileage engines.This time around I'm thinking of adding "Lucas" & see how it works, as I've heard some pretty good reports on it, just to see if it will prolong that oil breakdown, at mid change.

My low oil level light comes on

i presume that motor has a few miles on it. possibly the motor is so worn that it can't maintain a decent oil pressure. quick fix is to add heavier oil which hopefully will last for abit. be careful if you are in a cold climate as the thicker oil will make it harder to crank over in the winter.
