SOURCE: Oil pressure sensor is moving up and down while driving and need to check the fuse but can't find it.

No fuse for the switch on the engine although the cluster has a fuse for the instrument gauges

Most likely it's the oil sending sensor, located beside the oil filter. You can change it, just be sure to have old newspaper or rags laying around the area where you will work, because a little oil will be lost. The part isn't expensive, for mine on a Ford Expedition was around $35 and took 5 minutes to change. Just un-plug the connector going to the sensor, and a larger wrench will be needed, large (7/8, 15/16) somewhere in that range of size.

SOURCE: In my 02' Trailblazer oil pressure gauge goes below 0

I have this same problem with my 2002 trailblazer; however, I goofed up and had a mechanic look at it, since I was perplexed as to what was going on with it. He told me the oil pump needed replacing and it ended up costing me around a $950. Needless to say, it still happens. A grand down the drain - it wasn't the oil pump. The oil level is always good. This generally occurs when I've run the vehicle for a while and then come to a stop. It occurs quite often during the spring/summer and doesn't happen all that much during colder months.

My oil gauge is going back and forth on my 1996 Ford F250, I have change the oil coolant sensor. When I drive a few miles the oil gauge goes crazy. Need help? I have change the oil sending unit also.


The oil temperature sensor could be in the oil level sender unit - it depends how many connecting wires there are. If it is in there it would not be as accurate as if it is placed in the main oil gallery, perhaps combined with the oil pressure sensor.

I advise you to re-read your vehicle handbook and ensure you know the exact functions of the instruments. Often the oil gauge is a level gauge only until the engine is started and then becomes an oil pressure gauge, therefore a fluctuating gauge might indicate a fluctuating oil pressure...

If that is so, worrying about it now could save worrying more expensively later.

Replace the oil pressure sensor located near the oil filter. When this part starts to fail you will see your oil pressure gauge bounce all around

I have an 02 wrangler and the oil preasure goes down when Idling is that an oil pump going bad?


First we would need to know when this occurs. Asuming the oil level is at the full mark!. If the pressure goes up during acceleration and down at idle when engine is fully warmed up, then this is normal. An engine requires 10 psi of oil pressure per 1,000 rpm ( ex. 20 psi at 2,000 rpm, 25 psi at 2,500 rpm, and so on ) . If the gauge is moving back and forth erratically at idle , i would say the gauge is bad. If it drops to 0 while accelerating I would say your oil pump is bad. If from time to time it seems to work and other times it seems not to work, I would say the oil pressure sending unit for the gauge is bad. If the pump failed you would start to here a Knocking noise from the engine in a short period of time. Use the above scenario's to narrow down what it may be.

The needle is going back and forth and car seems to wants to shut off.


Specifically what Needle is going back and forth? You need to be more specificfor anyone to understand what your difficulty is. Are you speaking of the Tachometer? Speedometer? Oil Pressure Gauge? Ammeter or Voltmeter? Temperature Gauge?

Oil gauge fluctuates back and forth. sometimes


You'll need to determine if the oil pressure is actually changing, or if the sending unit or gauge is lying to you. Be certain the oil level is up to normal, then check the actual oil pressure with a test gauge. If the pressure varies (drops) at engine idle, perhaps your pressure bypass is defective, or perhaps the oil pump is worn. Testing with a known good pressure gauge should lead you in the right direction.

Oil gauge flutuating


I think I'd be real tempted to check connection at oil sender, for clean and tight, and if that doesn't help, for the price, I'd change it, but not knowing exactly which engine you have, I couldn't give you a ballpark on oil sender switch. You can look it up or call autozone, or similar for price.
