my oil light has came on n i was wondern if there is sumthing wrong
charles, first check your oil level and make sure that you do have enough oil in there. If your oil is at the proper level (check your dipstick markings) it is possible that you either have a bad oil pressure switch, a ground fault in the wire or bad compression on your engine, or a bad oil pump. You can do an Oil Pressure Switch Test
- Disconnect the Yel/Red Wire from the oil pressure switch.
- There should be continuity between the positive terminal and the engine(ground) with the engine stopped. There should be no continuity when the engine runs.

When the oil light is on, it is notifying you that there is not enough oil pressure in the engine to protect it. DO NOT RUN THE ENGINE IN THIS CONDITION. Doing so can cause permanent engine damage very quickly. Verify that your engine is not low on oil, that is the most common cause of no oil pressure. You can test the circuit from the oil pressure switch to the light in the dash without running the engine. With the ignition key to the “on” position (but the engine not running), the oil light should be on. If you disconnect the wire from the oil pressure switch, the light should go off. If it does not, the wire is grounded somewhere between the switch and the light in the dash. If it works as described, the switch is telling you that there is no oil pressure. You can remove the switch and connect a pressure gauge to verify whether or not there is oil pressure, or simply replace the switch if you think it is faulty (should be around $10 for a new one). If there is no oil pressure, you may have a clogged oil pickup in the oil pan or something wrong with the oil pump itself. The oil pump is replaceable without pulling the engine, but it may not be something you want to try yourself. You will need to remove the timing belt and the oil pan to get to the pump and the oil pickup, if you have to go that far you probably should replace the timing belt and the water pump while you have it apart.
The oil light comes on, if the oil pressure switch senses a loss in oil pressure. The first step is to check for oil level on the dipstick. If the oil level is ok, then check the oil pressure sending unit, if the oil level is low add oil to proper level. Sometimes, the oil pressure switch or sensor goes bad activating the oil light on the dashboard. When you remove the oil pressure switch if you see it soaked with oil, replace the switch. The oil light should come off. It it doesnt then you need to test the oil pressure with a pressure gage, which should be 10 psi at idle and 60 at 3000 rpm, by hooking up the tester where the oil sensor lives. If the test does not meet the above, there might be an obstruction in the pick up tube, or the engine main bearings are worn out. Simply your engine is worn. Oil pressure is not generated by the oil pump, but by the clearinances between the moving parts of the engine, particulary the main bearings, cap bearings. The oil pump only moves volume. If this is your problem, the im sorry because your engine needs to come apart. I suggest a remanufactured engine instead of overhauling because the costs are high. One from a salvage yard already tested or in good decent condition.
Additional information. It’s fairly common for this to be a simple oil pressure sensor / sending unit issue on Honda’s. If engine oil pressure is an issue the engine will typically run very rough, but caution should be used to prevent an engine failure. Then sensor is typically located on mount where the oil filter is screwed on. This can be a bit tricky to access, but can be done with patience and typically wrenches vs using sockets. Remove the airfilter and airbox if they are obstructing the access to the sensor. There will be a rubber boot protecting the single wire. It will likely distengrate during removal, but pry carefully to try to salvage it. Remove the old sensor and connect a pressure test kit. Run the engine and let it warm up. Typically on older models the cooling fan should come on a couple of times. At idle you should have at least 14psi At 3000 RPM it should be 54- 60 psi. Check it a few times to confirm.
