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).

Where is the oil pressure switch on a chevy silverodo 2006.


What engine size , because could have come with a few different ones ? Engine oil pressure sensor is a input to the PCM - engine computer . This will turn on check engine light if thier is a problem ! What is the problem your having , oil light on , oil pressure gauge not working ?
Engine Oil Pressure Gage
The instrument panel cluster (IPC) displays the engine oil pressure as determined by the powertrain control module (PCM). The IPC receives a class 2 message from the PCM indicating the engine oil pressure. The engine oil pressure gage defaults to 0 kPa (0 psi) or below if:
• The PCM detects a malfunction in the engine oil pressure sensor circuit.
• The IPC detects a loss of class 2 communications with the PCM.

WHAT IS THE HEAD TIGHTENING SEQUENCE FOR A WISCONSIN TJD MOTOR


I looked up the engine in my old archives and didn't find a sequence but the spec is 22 to 24 ft.lbs. You can't go wrong going from the center toward the outside in several stages; that is start with 10 ft.lbs. on all bolts, then 16 ft.lbs. and finally 24 ft.lbs.
Oil the bolts or use anti seize on the threads and under the heads of the bolts so they all are lubricated and turn equally. Make sure each bolt is turning while the torque limit is attained [dynamic torque v.s. static friction of a bolt not rotating.
Since these engines are flat head and do not have hollow cooling passages, the cylinder head torque isn't as critical as a water cooled engine.

Got a m610 with vh4d wisconsin had fire at plug and it just vanished no spark at coil but have power to coil


Check wires. You have a short circuit. May need a new set of spark plug wires to include ignition wire.

My car is Volkswagen polo 2001 1.4 automat. After driving 8-10 miles at a low speed(30-40 mile/h) oil pressure warning appear at the dash board. When I push the accelerator the oil pressure warning...


Do not assume that the low oil pressure warning is a false one or that you only have a faulty oil pressure sensor. Your engine may in fact be running with low oil pressure once the oil heats up and thins out. 8-10 miles of running is enough to get the oil hot. It is significant that you only get the low oil pressure warning once the engine oil is warmed up.

If the oil pressure in the engine is low, engine lubrication will be impaired and the engine can be badly damaged so you need to run an engine oil pressure check.

1. How long has it been since you have changed the oil in the engine? If it has not been changed in the past 6 months then change it and change the oil filter at the same time. You must only use the oil specified by VW for that particular engine.

2. When new oil is heated it thins. If it is old and contaminated it will be even thinner when warm. You will get less oil pressure when the oil is thin and hot and more oil pressure when it is thick and cold. Fresh new oil is a little thicker as it has not been diluted with petrol and other contaminants.
Oil pressure also varies with engine speed (RPM). At idle or low engine RPM the oil pressure is lower.

3. OIL PRESSURE CHECK
After the oil is changed the car needs to be run to check if the oil pressure warning still appears. (I suspect that it probably will). If it does appear then an independent oil pressure gauge needs to be connected up to the lubrication system in the car to check the engine oil pressure. This is best done when the engine oil is hot because this is when you are getting the low pressure warning. Any competent mechanic will be able to do this. ( The useless ones will not). The oil pressure can then be properly checked on the gauge at various engine RPM. If there is a low oil pressure reading from the gauge then there could be a problem with the oil pump, the oil pick up or the oil pressure relief valve in the engine.

4. You mentioned that you see the oil pressure warning disappears once you accelerate. I suggest this is only occurring because with an increase in engine speed (higher RPM) the oil pump speed is increasing and the low oil pressure problem is being overcome temporarily. However as soon as the engine RPM drops the oil warning will appear again which means the engine is running with below minimum oil pressure at that RPM.

Even when you get no warning, the oil pressure in the engine could still be running significantly below the optimum level.


5. It is possible that the oil pressure is fine and that the problem is an electrical gremlin as these cars suffer from a variety of electrical faults. However from what you have described I think there is a problem with low oil pressure in the engine and until it is properly checked it is unwise to assume that you are just getting false oil pressure warnings.

I hope this helps.

How do I check and possibly replace the engine oil pressure sensor in a 2006 GMC Envoy Denali?


Oil Pressure Test Check for proper oil pressure at the sending unit passage with an externally mounted mechanical oil pressure gauge. A tachometer may also be needed, as some specifications may require running the engine at a specific RPM.
  1. While the engine is cold, locate and remove the oil pressure sending unit.
  2. Following the manufacturer's instructions, connect a mechanical oil pressure gauge and, if necessary, a tachometer to the engine.
  3. Start the engine and allow it to idle.
  4. Note and record the oil pressure reading when the engine is cold. The engine may need to run at a specified RPM, if so check the vehicle's specification.
  5. Run the engine until normal operating temperature is reached.
  6. Check the oil pressure reading again with the engine hot and record the value. Turn off the engine.
Compare the hot oil pressure reading to the specification. If the reading is low, check the cold pressure reading against the specification. If the cold pressure is well above the specification, and the hot reading was lower than the specification, the engine may have the wrong viscosity oil. Change the oil, making sure to use the proper grade and quantity, and then repeat the test.
Low oil pressure readings could be attributed to internal component wear, pump related problems, a low oil level, or oil viscosity that is too low. High oil pressure readings could be caused by an overfilled crankcase, too high of an oil viscosity or a faulty pressure relief valve.
