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.

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).

2007 Buick oil light comes on and off at random. Recently changed oil. GTX extended milage. .5w30. Oil level good. Any ideas


Oil pressure sensor, or most likely, oil level sensor, either sensors, wires, or connections.

What are the output specifications for the oil pressure transmitter (it's a 2-wire sensor)in a 2001 Bentley Arnage? (I need the mA outputs corresponding to various oil pressures, at say, 10psi, 20psi,


the oil pressure hot on your test gauge will be below recommended pressure necessary for the proper lubrication of the engine . The control module as you say will be set higher to notify you before that pressure is reached so that there is sufficient time to shut down the engine

Oil prresure indicator drops to 0 when vehicule stop


Most likely a bad sensor. If you had 0 pressure you would know by vehicle reaction. Get an oil pressure gauge and remove sensor and install gauge. What is actual pressure? Bad sensor? Always a good idea to do internal clean, cheapest is SEAFOAM

Hi: I read your answer to the problem with the 1999 Mercury Mistique temperature gauge. I'm having a similar problem. My temperature gauge is broken in the cold position. And, as far as I can tell,...


Very correct the ECT is a 2 wire thermistor,when coolant temp increases, the resistance andsignal voltage decrease,If you disconnect the sensor the fan goes on, you just trouble shooted the vehicle cooling fan switch, If anything the signal to the gauge itself may be non-op and not getting to the indicator, try this with vehicle at warm up temperature if you turn the A/C does the fan turn on.it should if it doesnt the power juction box (fuse and relay in engine compartment should be checked, for any opeen fuses, By the way the guage information is from the PCM

Why won't the oil and temperature gauge work on


you should switch the temperature sensor and oil pressure sensor you had on your first engine,because your new engine must come with the light indicator dashboard so the sensor of your new engine are not compatible with your gauges....lipak!...

Oil pressure gauge is pegged out all the time doesnt matter if the key is on off or if the duramax is running. im out of ideas to check my grounds are good, my cluster is good, all fuses and wires as far...


Sending unit is bad or you have a Open wire between the gauge and the sensor. Think back to when it started having the problem and you may have a clue there. Id bet the sending unit is bad though since they do go bad on occasion.
It would also do this if it was unplugged from the sending unit.
