SOURCE: Oil Pressure going up and down during acceleration and decel.

Hi, this is a faulty oil pump and , it should be replaced asap. make sure the mechanic replaces the oil screen as well.

You can test the pressure gauge and True oil pressure by using the guide below.



Testing the Oil Pressure Gauge

* Test the gauge by grounding the wire that leads to the sending unit on the block.
* When the wire is grounded with the key switch on, the gauge should show maximum oil pressure, or the light should go on.
* If either happens, the gauge and wiring are good and the sending unit is at fault.

Testing Oil Pressure

Pressure can be tested by temporarily installing an oil pressure gauge in place of the sending unit. Before testing, look up the oil pressure specifications for your vehicle in the appropriate service manual.

* Bring the engine up to operating temperature.
* Now shut the engine off.
* Locate the oil pressure sending unit; usually it is on the lower side of the engine block.
* disconnect the wire from the sending unit and use an Open Ended Wrench to remove the sender. using pliers can damage the unit.

* Tighten the oil pressure test gauge into the hole in the block where the sender was removed.

* Check the engine's oil level and fill, if required.

WARNING
Be extremely careful when working near a running engine. Always wear safety goggles or glasses with side shields when working around moving machinery and be sure that your clothing is not loose.

* Now turn the engine on and check the oil pressure on the gauge.
o Watch as the engine warms to note any excessive drops due to temperature.
o Make sure the engine speed is set to specifications for testing pressure.
o if necessary, us a Tachometer and adjust the engine idle speed.
* Record the measured oil pressure, then turn off the engine.
* Compare the test results with the manufacturer's specifications.
o If the oil pressure is within specifications, this shows that the oil pressure sending unit may not be working correctly.
o In many cases, replacing the oil sending unit will correct the problem.
* After the test is complete, reinstall the oil pressure sending unit, start the engine, and confirm there are no leaks.

SOURCE: 2005 toyota corolla motor oil capacity?

if you have a 1ZZ engine

4.2 quarts, 4.4 quarts with oil filter change

if you have the 2ZZ engine (XRS model) it is

4.4 quarts, 4.6 quarts with oil filter change

NOTE these are updated capacities that reflect changes identified in TSB: TSB-0134-08 issued July 15, 2008.
Your owners manual will reflect a lesser quantity that Toyota has since revised.

SOURCE: Replacement of 06 toyota corolla

I own a 2006 Corolla and can give the following advice. Begin by purchasing a quality replacement belt. I highly recommend the Goodyear Gatorback serpentine belt due to it's quality and unique ribbing designed to eliminate the high pitched chirps and squeals which commonly occur with the original equipment belt on these cars. You will need a 3/8 breaker bar with a 19mm socket and a piece of pipe at least 18" long to slip over the end of the breaker bar to provide additional leverage. This will be used to remove the tension on the belt for removal and installation. You'll also need a metric socket set to aid in removal of the plastic cover that sits on top of the engine. Start the process by removing the plastic cover using a ratchet and 10mm socket on the two acorn head nuts near the front of the cover. Then remove the two plastic push-in fasteners at the rear of the cover by gently prying in an upward direction. Removal of this cover gives more room to help you work the new belt around the pulleys. Make a diagram of the pulleys and belt routing as a reference to help you when installing the new belt. Find the belt tensioner (it looks like an arm with a small piston-like device attached to one end and a smooth faced pulley on the other end.) You will see what looks like two hex shaped bolt heads cast into the metal of the tensioner arm. Place the breaker bar with 19mm socket onto the upper hex casting so that the breaker bar handle points straight up. Slip the pipe over the handle of the breaker bar and pull toward the front of the car. This will relieve the tension and allow you to remove the belt from the alternator pulley. Once the belt is free set the breaker bar aside and work the belt off all the pulleys. Installing the new belt can be a little challenging and will be extremely difficult if you start in the wrong place. Although the new belt goes over the alternator pulley last, it is in fact where you should begin the installation. You'll notice that the top path of the belt goes from a large pulley at the rear of the engine straight to the alternator pulley at the front of the engine. What you want to do is put the belt on the alternator pulley and then begin routing the lower path of the belt around all the pulleys and the pulley on the tensioner arm until it is around everything except the large pulley at the rear of the engine. Then take a piece of stiff wire and bend it into a hook on both ends so that you can gently remove the belt from the alternator pulley and use the wire hook to hold it in line with the other pulleys while allowing enough slack to work it over the last large pulley in the back. I hook mine to a convenient hose located in line with the pulleys just below the alternator. I found that the extension pipe was handy to help nudge the belt onto the lower ribbed pulleys because I couldn't get my hand into the narrow space. Once you have the belt routed and properly positioned on all the pulleys use the breaker bar and extension pipe to again relieve the tension allowing you to slip the last loop of the belt over the alternator pulley. Take a flashlight and carefully examine the belt routing to make sure it is properly positioned on all the pulleys, especially the ribbed ones. Improper installation will cause the belt to jump off and/or damage itself. Once you are satisfied with the belt installation you can replace the plastic cover on the engine. Start the engine as a final check that everything is working properly and enjoy your new quiet belt. This looks like a complicated procedure but will take less than one hour and those that are mechanically inclined should be able to get it done in 30 minutes or less. Hope this helps you.

2003 Toyota Corolla oil pressure light flickers then goes to solid after a short period of time. Last time this happened, changed oil and filters and light went away. Now after maybe 1000 miles of driving,...


see if you have any oil level or pressure sensors. sometimes these can get gunked up. You may need a new oil pump. I suggest you start using a senthetic oil (valvoline,mobil 1 is reccomended) after u get the problem fixed.

04 corolla. Oil light comes on. Full of oil.


the oil pump on any car is rarely the cause of low oil pressure. if you remove the oil pressure sending unit and install an oil pressure gauge,even the type you can buy as an add on,and the reading you get is low.the problem is genrally worn out main crankshaft bearings.to avoid unneseary replacement of these,you should buy some plasti-gauge from an auto part store remove the bearing caps one at a time and measure the clearance this way.there is a risk here because the smallest grain off dirt that getts into the bearing, crankshft will ruin the bearing when you restart it.if these are worn out you probabably shoul consider replacing the engine because the other bearings are probably also worn out by this time.
