Your best bet , take it to a qualified repair shop. Have it checked for DTC'S - diagnostic trouble code's

Audible Warnings Description and Operation
The audible warnings alert the driver of a system concern or a critical vehicle condition. The instrument panel cluster (IPC) generates audible warnings through an internal acoustic speaker. The IPC receives audible warning requests via the serial data circuit. If the IPC receives multiple audible warning requests, the warning with the highest priority sounds first. The following lists the audible warning priority and the pulse rate:
Fast rate chime (200 pulses per minute)
Medium rate chime (150 pulses per minute)
Slow rate chime (50 pulses per minute)
Single chime
Door Ajar Warning
The IPC activates the door ajar audible warning as requested by the body control module (BCM). The BCM sends a serial data message to the IPC indicating the chime frequency and duration. The door ajar warning sounds and the appropriate DOOR AJAR indicator illuminates in the driver information center (DIC) when the following occurs:
• The body control module (BCM) determines that a door, driver door, passenger door. The IPC receives a serial data message from the BCM indicating the door ajar status.
• The vehicle is not in park. The IPC receives a serial data message from the BCM indicating the gear position.
• The vehicle speed is greater than 8.05 km/h (5 MPH). The IPC uses the vehicle speed information from the ECM to calculate the vehicle speed.
Fasten Safety Belt Warning
The IPC activates the fasten safety belt audible warning as requested by the BCM. The BCM sends a serial data message to the IPC indicating the chime frequency and duration. The fasten safety belt warning sounds and the fasten safety belt indicator illuminates when the following occurs:
• The ignition switch transitions to ON.
• The inflatable restraint sensing and diagnostic module (SDM) detects that the driver's seat belt is not buckled. The IPC receives a serial data message from the SDM indicating the drivers seat belt status.
If the seat belt is buckled when the ignition is turned ON, the chime will not sound. If the seat belt is buckled while the chime is sounding, the chime will stop. If the seat belt is unbuckled after the initial transition to ON, the chime will not sound.
Key-In-Ignition Warning
The IPC activates the key-in-ignition audible warning as requested by the BCM. The BCM sends a serial data message to the IPC indicating the chime frequency and duration. The key-in-ignition warning sounds when the following occurs:
• The ignition switch is OFF.
• The body control module (BCM) determines that the driver's door is open. The IPC receives a serial data message from the BCM indicating the door ajar status.
• The BCM determines that the key-in-ignition switch is closed and the signal circuit is low. The IPC receives a serial data message from the BCM indicating the key-in-ignition status.
Lights On Warning
The IPC activates the lights on warning as requested by the body control module (BCM). The BCM sends a serial data message to the IPC indicating the chime frequency and duration. The lights on warning sounds when the following occurs:
• The ignition is OFF.
• The BCM determines that the drivers door is open and the signal circuit is low.
• The BCM determines that the headlamp switch is in the park or head position.
Park Brake Warning
The IPC activates the park brake audible warning as requested by the BCM. The BCM sends a serial data message to the IPC indicating the chime frequency and duration.
• The body control module (BCM) determines that the park brake is applied.
• The vehicle is not in park. The IPC receives a serial data message from the engine control module (ECM) indicating the gear position.
• The vehicle speed is greater than 8.05 km/h (5 mph). The IPC uses the vehicle speed signal information from the engine control module (ECM) in order to calculate the vehicle speed.
Additional Warnings
The following warnings have an associated instrument panel cluster (IPC) indicator or driver information center (DIC) message:
• Check Oil Level
The IPC activates the audible warning as requested by the BCM. The BCM sends a serial data message to the chime producer indicating the chime frequency and duration.
• Low Fuel
The IPC activates the audible warning as requested by the BCM. The BCM sends a serial data message to the chime producer indicating the chime frequency and duration.
• Oil Pressure Low Stop Engine
The IPC activates the audible warning as requested by the BCM. The BCM sends a serial data message to the chime producer indicating the chime frequency and duration.
• Reduced Engine Power
The IPC activates the audible warning as requested by the BCM. The BCM sends a serial data message to the chime producer indicating the chime frequency and duration.
• Trans Hot Idle Engine
The IPC activates the audible warning as requested by the BCM. The BCM sends a serial data message to the chime producer indicating the chime frequency and duration.
• Turn Signal On
The IPC activates the audible warning as requested by the BCM. The BCM sends a serial data message to the chime producer indicating the chime frequency and duration

SOURCE: the oil pressure light and alarm keeps going off

Incorrect level. Check level at operating temps and while the engine is running. By sump and stainer you meant that you removed the oil pan off the car and cleaned the pickup tube of the oil pump? I'd suggest hooking up an oil pressure gauge so you'll know which part of the engine is starving oil and setting the warning.

SOURCE: 1996 oldsmobile aurora oil pressure

The Aurora is a low pressure oil system. The only solution available at this time is to increase the oil weight. I went o straight 30W to solve the idle alarm issue. Some use 20W oil and that works too.
With 20W you will be at 80 to 90psi cold then drop to 20-30psi hot.
I first replaced the oil pressure gauge and it was worse. I put the original back in and it was better. Then went to 30W and all is fine.
Running it that way for a few years now.

Where the location to oil pump


The engine oil pump draws oil from the oil pan or sump under the engine. Most designs place the pump withing the sump for convenience of design and efficiency of operation and in particular to provide the shortest time to achieve full pressure after a cold start and possible drain-back. Some designs, mostly push-rod engines, drive the pump at half crankshaft speed but modern design tends to mount the pump on the front of the crank driving direct or close to the front of the crank via a chain or gear drive

A few designs placed the pump at the top of the engine and sharing a timed drive with the distributor. Surprisingly these worked quite well until the engine had lost it's newness and then the length of time until oil light out would extend and extend and extend. It was reckoned this wasn't a cause for alarm until it took one minute...

How do you load the cam actuator after changing the head gasket on a 2006 Hummer H3?


two ways: cranking the engine by turning the crank pulley bolt. Best done with valve cover off to verify full engine oil prime. The other economical way is by disabling the ignition and fuel pump (fuse removal) and cranking engine for 5 seconds, three times each.

The oil alarm come on after a 10mn drive at slow down


Check for low oil level on engine dipstick. If not that, change the oil, it is getting too thick. If not that, there is a clog in the oil pump or the oil filter. Change the oil filter first.

HOW TO TELL IF OIL PUMP IS GOING BAD ON 1996 TOYOTA CAMRY??


Low oil pressure will not cause the alarm to set and shut the engine down, usually if there is a switch turning it to off disables the alarm and lets the car start. If the oil light on the dash goes off when the engine is cranking or after it starts chances are that there is no problem with the oil pump. I need to know what the problem is exactly at this time, does the engine turn over but not fire up or does it do nothing at all when trying to start it? Do the dash lights turn on when the key is on? Is there an alarm sound from the horn when trying to start it?

My 06 hummer h3 shuts off when you turn the steering wheel


Try unplugging the power steering pressure sensor, It's either in the pressure line or on the back of the pump. It sends a signal to the PCM to increase the RPMs at low speed when more power from the pump is required when parking and such.

Oil indicator light keeps flashing and eventually sounds a beeping alarm. Only thing is there is the correct amount of oil in the car. Been to garage and they checked level. Is this simply a switch problem...


The only way to tell for sure is to temporarily install a mechanical pressure gauge and read the actual pressure. That will determine the next course of action--replace the pressure sensor/switch, or recommend remedial action within the engine itself (worn bearings, worn oil pump, or plugged intake screen). Hope this helps!

Warning lights


Either you have a lubrication problem or a bad oil pressure sender. You need to have it scanned for DTC and do an oil pressure test before you seize your engine.

Where is the oil sensor on 1999 jetta. The light and beeping sound comes on but the oil isnt low. how much do would it cost to replace it you think.


The oil pressure switch is located on the oil filter flange for both gas and diesel engines. Incorrect oil viscosity can influence engine oil pressure. Before performing repairs, ensure that the engine has sufficient quantity of fresh oil and correct viscosity. Always check level when the engine has fully warmed up (after radiator cooling fan has operated) then check your dip stick. During high speed turning the oil in the pan sloshes to one side and starving the oil pump causing a warning indication. So check it after it has pressurized the system to get accurate reading. To much oil can cause 02 sensor malfunction so don't over fill.
