The oil pressure switch is also known as the oil pressure sensor. This isn't a hard task and it can be done easily when you're performing a routine oil change. The placement of the oil pressure switch will vary with car make. Since it can be difficult to obtain good access to the oil pressure switch when the oil filter is on, changing the oil pressure switch as part of a service is suggested. To do this, place a large basin under the oil pan and open the drain plug with a wrench.

Then, using an oil filter wrench, loosen the oil filter before removing it by hand. There will be a rubber boot covering and protecting the switch to keep dirt away. Then, fit your wrench over the oil pressure switch and add the extender handle.

Loosen the switch before you finish unscrewing and removing it by hand. If any oil spills when you remove the oil pressure switch, wipe it up with a rag before you screw the new switch in with your hand. Tighten it all the way down with your socket wrench. Then, snap the connector on to the new switch and roll down the boot so the oil pressure switch is fully protected. Clip the cable back onto the switch.

Dip your finger in the old oil in your basin and run over the rubber gasket on the new filter before you screw it onto the engine. Use the oil filter wrench to secure it firmly. Then, close the drain plug on the oil pan and refill the engine with the correct amount of new oil; your service manual will tell you how much to put in. Finish by putting the oil cap back on.

Check your work before you clean up by switching on the engine and checking that the oil pressure switch is working correctly. It should not come on at all if the work carried out is satisfactory. Finally, dispose of the old oil and filter responsibly. We welcome your comments and suggestions. All information is provided "AS IS.

Hi, up in the mountains today pootling along minding my own business and noticed the oil pressure gauge was reading nothing.Having problems with your car's oil pressure sensor? Have you noticed something different or weird going on lately?

Do you think you have a faulty oil pressure sensor and it's not reading correctly? Find the answers to your questions and learn to troubleshoot a faulty oil pressure sensor with this helpful guide below.

1HD-T Oil pressure sender

An oil pressure sensor is a device that monitors the oil pressure in your car's engine. It's a fairly small piece of your system, but is one of the most important sensors in your vehicle. It will alert you if the oil pressure in your engine is running lowwhich will mean it is running out of oil. Running an engine with low oil pressure can cause significant damage and may total your engine and cost thousands of dollars in auto repair. But how will you know when an oil pressure sensor is just faulty and not reading accurately?

Take a look at the symptoms of a faulty oil pressure sensor. Or, if the light is coming on and off while you are driving, it's most likely a faulty sensor. But just to make sure, always check your oil whenever the light comes on again.

It will only cost a few dollars to replace a sensor instead of an engine. When an engine is idle, it is normal that the oil pressure will be low too, so your sensor will have a low reading.

This means that your oil pressure sensor light should not be coming on at this time, and if it does, there is definitely something wrong with it.

But again, as mentioned above, it's best to make sure. Park your car some place safely out of the way and check your oil level immediately. Make sure it's within the minimum and maximum levels of your dip stick; anything below or over the limit is bad for your engine. If your oil pressure sensor light comes on and is accompanied by a strange ticking noise coming from the engine, it would be best to stop your car as soon as possible.

This case is usually not indicative of a bad sensor; rather, your sensor might be telling you that you really are running low on oil. You may have just filled up your oil before leaving the house, but there might be a leak in your oil line causing the levels to drop. First, check under the car and the road your car just passed. If your car is still parked, look beneath it and see if there are any oil marks. Also, pop your hood and check the oil and see if the oil level has significantly decreased since you last filled it.

If any of this is the case, it means your oil pressure sensor is working just right and instead, you have an oil leak that needs repair.There's a detailed 3 minute video called Lubrication: Oil Pressure Switch in the video course. The oil pressure gauge is one of the most important instruments in a car.

It acts as an indicator of the engine 's overall well-being and as an early-warning system, giving advance notice of any problems so you can investigate the cause before an expensive breakdown occurs. The gauge monitors the oil pressure in one of the main oilways near to the pump and filter. To do this it has a tapping in the engine blockinto which is screwed a sensor for electric gauges or an oil pipe take-off for mechanical gauges.

The sensor for the oil warning light is screwed into the union or T-piece at this point, whether or not the car is fitted with an oil pressure gauge. Mechanical gauges work by literally forcing the needle around the dial under pressure from the engine.

Electric gauges, on the other hand, work by using the sensor screwed into the engine block to produce a variable resistance that affects the amount of current passing through the circuit containing the gauge and sensor. Oil is sent to the gauge from the tapping in the engine's oilway by a small-bore 3mm pipe, usually copper or plastic.

The pipe is routed away from anything that could damage it, because if the pipe is punctured the engine's oil would leak out. The pipe enters the passenger compartment via a grommetted hole in the bulkhead, and joins the stub on the back of the gauge via a knurled connector.

The gauge contains a flexible coiled tube called a bulb, the open end of which is rigidly mounted to the gauge's outer casing. The other end of the bulb is closed and connected by a lightweight linkage to the bottom end of the needle, which is itself mounted on a pivot. Oil is fed into the bulb from the supply pipe at very nearly the same pressure as it left the engine.

The bulb tries to straighten under the pressure and in doing so moves the needle around the calibrated gauge scale.

The greater the pressure, the more the needle moves. Electric current is supplied to the gauge from a fused power supply in practice the current is taken from one of the many wires or printed tracks behind the dashboard. The current passes through a wire-wound coil mounted around or within the needle's pivot and produces a magnetic field that moves the needle across the calibrated scale of the gauge.

How far across the scale the needle goes - what reading it gives - depends on how much current flows through the gauge. This in turn depends on the resistance of the gauge's return wire which is earthed to the engine block through the sensor. The resistance of the sensor depends on the oil pressure. Oil enters the end of the sensor which is screwed into the engine block and pushes against a diaphragm.

The diaphragm moves a wiper inside the sensor which runs up or down a blade of known resistance this blade is connected to the return wire from the gauge. The more the diaphragm moves under pressure, the further down the resistance blade the wiper moves. So the resistance of the sensor varies with oil pressure and moves the needle of the gauge accordingly.

All gauges are illuminated so that they can be read at night. Integral gauges are lit from one of the panel lights which also illuminate the rest of the instruments, while separate gauges have a small 0. Electric gauges are easier to integrate into the modern one-piece printed circuit instrument panels used in most modern cars, they are less bulky and it's easier to route and connect a wire than a pipe. Mechanical gauges are not as common as electric ones, although they are still available in accessory shops.The oil pressure sensor on a Chevrolet 4.

This sensor measures the pressure of the engine oil and relays this data to the PCM. When the PCM detects low oil pressure it illuminates the oil pressure light. As time passes, the oil pressure sensor may develop an oil leak or begin providing the PCM with inaccurate pressure information, necessitating its replacement. New oil pressure sensors can be purchased from automotive parts stores and Chevrolet dealerships. Locate the oil pressure sensor. It is on the right side of the engine, just below the intake manifold.

It is approximately 3-inches long and is made from black plastic. A two-wire electrical connector is attached to the end of the sensor. Clean any residual oil off of the sensor and start the engine.

Watch the sensor to see if any oil leaks out. If oil seeps out of the sensor at any point, then the sensor is faulty. Turn off the engine and disconnect the oil pressure sensor's electrical connector and remove the sensor from the engine using a 1-inch box-end wrench.

Troubleshooting a Faulty Oil Pressure Sensor

Start the engine and watch the gauge. It should read at least 6 psi at rpm. If the oil pressure meets or exceeds this specification but the oil pressure light is on, then the sensor is faulty and must be replaced.

Carrying on from Lorin's Oil Pressure Woes thread and the ensuing discussion over oil pressure, I took delivery of a comprehensive oil pressure testing kit and gauge today from RDGTools.

Having replaced the pressure sender and having performed the FSM checks, I could not find any reason why the gauge didn't work. Slightly worried that in fact I had NO oil pressure at all, I thought it best to check it out. I have had the sender off a couple of times and it's a right little bugger to get at, so I thought I'd post the wisdom for anyone else going this way.

Why Toyota Land Cruiser Loud Engine Knock Pt. 4: Lower Oil Pan Comes Off. What's Chewing?

The sender is a small round canister just to the right and below of the oil filter. It has two wires; one spade terminal and one sort of clip on swivel that goes onto the central little 'tit' on the canister. Best thing to do is remove the oil filter. It gives you so much more room. The undo the two 12mm headed bolts that secure the dipstick tube and twizzle it anti clockwise out of the way. Next undo a connector that goes to a sensor in the block right above the sender unit.

This allows you to wield a spanner. Disconnect the two leads on the sender. You can use a tie wrap or string to try and pull some of the loom out of the way if you are struggling. I have been in there so many times I'm pretty practised at it.

Using a 14mm open ended spanner you can now just get onto the nut which is part of the back of the unit. You'll probably have to undo it one facet at a time reversing the spanner to get onto the nut. There is sufficient room to get quite a good arc. And as they say is it.
