SOURCE: oil pressure went slightly higher than 275 kpa

hi! there,well actually oil pressure that you get in your gauge seems to be that you need to change oil it was below to the standard oil pressure of engine,approximately 275 kpa is 39 psig
w/c is below to 90 psig,the important here is you to avoid/prevent knocking your engine and besides this very significant of sensoring
engine activities to prevent mor costly maintenace in your car.so sent your car to service car center to change oil specially also to change your oil filter.thank/s

SOURCE: the kPa oil pressure drops when the car warms up

how many miles are your lesabre ... could be an electrical problem or it could be a high mileage ( engine worn out ) issue are there any sounds that are co,ing from the bottom of the engine?

Is there a fuse that works the oil pressure gauge and the battery gauge for a 2005 chevy trailblazer


NO , there is not a fuse just for those two thing's ! There are two power supply's for the whole insturment cluster . You could need a new cluster or the ECM isn't sending this info. to the cluster . Could have DTC'S - diagnostic trouble codes stored in the PCM or the insturment cluster . Without knowing how this works (insturment cluster gets it's info.) Your best bet , take it to a qualified repair shop that has the knowledge and test equipment to diagnose this problem.
Engine Oil Pressure Gage
The instrument panel cluster (IPC) displays the engine oil pressure as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the engine oil pressure. The engine oil pressure gage defaults to 0 psi (0 kPa) or below if:
• The ECM detects a malfunction in the engine oil pressure sensor circuit.
• The IPC detects a loss of serial data communications with the ECM.
For the 4.2L LL8, the ECM uses an engine oil switch that is open when the oil pressure is normal and closed when the oil pressure is low. At normal pressure, the engine oil pressure gage will display 275 kPa (40 psi). At low pressure, the gage will go to 0 kPa and the low pressure warning will be displayed in the driver information center (DIC). At high pressure, the gage will display 551 kPa (80 psi). Any values between these three values are calculated values determined by the ECM.

Voltmeter
The instrument panel cluster (IPC) displays the vehicle voltage based on the information from the body control module (BCM). The IPC uses the serial data information from the BCM to provide a voltage level indication on the voltmeter.

DTC P0521: Engine Oil Pressure (EOP) Sensor Performance

DTC P0522 Engine Oil Pressure (EOP) Sensor Circuit Low Voltage
DTC P0523 Engine Oil Pressure (EOP) Sensor Circuit High Voltage

Volt Gage Inaccurate or Inoperative

Install a scan tool.
Turn the ignition ON, with the engine OFF.
With the scan tool, perform the instrument panel cluster (IPC) gauges output control.
Does the volt gauge move up and down when commanded?

Need to know where the fuse is for oil sending unit on a 1998 Buick Park Avenue with a 3800 v6


There is no fuse for the oil sending unit ! Oil lite on , gauge not working ? Do you know what PCM five volt reference voltage is ? The PCM - engine computer supply's a stable 5 volt voltage to engine sensors . The oil pressure sensor is one of these sensors .
Engine Oil Pressure Sensor
The engine oil pressure sensor is a solid state transducer. The engine oil pressure sensor sends oil pressure information to the PCM. The PCM then transmits the oil pressure information to the IPC via serial data.
Engine oil pressure is displayed on the scan tool in volts. A low voltage reading indicates low oil pressure. As the oil pressure increases, the voltage level also increases. The normal range of the engine oil level sensor signal voltage is 0.5 volts at 0 kPa (0 psi) to 4.5 volts at 883 kPa (128 psi).

Oil pressure


30 PSI hot idle is ok, 40-50 PSI at freeway speeds hot is good. this is based on using the correct weight of oil which is 10W-30W
