I went out and started up my 96 accord (with JDM H22) and right away my oil light started blinking. It wasn't random blinking, it was almost like it was timed, on, off, on, off, on, off etc. I've got a oil pressure gauge and at the time was reading 50 psi (engine temp was about 140.) Obvousily this isn't a oil pressure issue. I shut the car off, checked the level, ok, and re-started it and the light never come on again. This is the first time this has happened and the car has worked great sence this, however this light worries me. Is there somthing else Im missing here that would make it flash like that? Is there a code system or somthing?

any help is great.

oil pressure sending unit above the oil filter; when they start to leak they can break the electrical connection because oil does not conduct electricity.

chadnixon

no thats not it. It was blinking almost like a code, on off on off on off, etc. I even unpluged the sending unit above the filter and installed a manual gauge to make sure my electronic one was reading correctly, and it is. However, when I unpluged that sender and took it for a drive it was starting to flicker, and then blinked again on off on off on off etc when I came to a stop.

There must be somthing else wired to that light, because I had the stock sensor out and it wasnt touching a ground or anything to make a connection yet the light was still flickering.

mine tends to do that, scares the hell outta too..and it didn't start happening until after i put a new oil pan in too, it's a headscratcher for me so idunno what to tell you bro

Here's a link to the schematic;

The oil pressure switch acts as a ground to energize the integrated control, but the Voltage Regulator is also a possible fault of the circuit.

Its hard to make sence of that diagram. Based one what I've seen in the past the oil pressure switch is open when theres pressure, and closed without, which causes the power to go to ground completing the circuit thus turning the light on. By looking at that diagram it doesn't make any sence.

If thats the case, then I suppose you dont know how to read wiring schematics.

chadnixon

How so? Are you seeing somthing im not?

double check to see if your oil level is low. I had went through two H22A's in my car and my oil pressure light would always blink when my oil was low (I guess I'm slowly burning oil).

chadnixon

my oil level is fine. Ive found some info that says some car makers use one light to warn you of multiple functions rather then having too many lights on the dash. It says its common a blinking oil light means a charging system issue, and after doing some reasearch I see that my oil light is wired through a flasher and then to the regulator on the side of the alternator. Im thinking that's my issue and my alternator is slowly on it's way out. Ive got to wait until the next time the light flashes and check the charging rate to make sure that it's ok.

im certian this isnt oil related.

The Battery light flashes if the alternator is gunked, not the oil light.

It is something wrong with your oil/oil delivery/sensors.

chadnixon

no..no...it isn't.

Like I said, I had the oil pressure sensor setting on the bench beside me. I've changed the oil, made sure the level was dead on. Have had three gauges, one elecrtonic, two manual..all reading the same.

And the battery light shouldn't flash if the alt is out, it should simpily be on. Honda uses a system that holds about .5V at the ground side of the light, as long as that .5v is present, the light cant ground therefor will not be on. When your alt stops charging this .5V no longer exists, thus alowing the light to ground turning it on. In the case of overcharging, it works the same way.

Yep you're on to me, I draw up schematics to confuse people.

But then again I'm not the one with a blinking oil light, and too stubborn to diagnose the electrical problem.


There must be somthing else wired to that light, because I had the stock sensor out and it wasnt touching a ground or anything to make a connection yet the light was still flickering.

In your very own post you said the light was blinking; yet you seem to think I drew the integrated control unit into the schematic?

chadnixon

Thats not what I was saying. I was comparing it to my diagrams from my manual, and it was a bit different, which was confusing me. In my manual it was showing the oil light and the battery light both wired to the blu/wht wire that is coming off my alternator which is feeding that ICU. And going by what my local dealer told me my car isnt fitted with a ICU because of the model. He told me that only certian models have this ICU and mine doesn't. Aparently he was wrong because I looked under my dash and low and behold...a ICU.

Sorry if it appeared to you that I wasn't finding your information helpfull. Im just going by many peoples opinions most of which have no idea what they are talking about.

With that being said, heres a update. When my engine detects a moment in which there is no oil pressure it flicks on the light, as does every car. When the switch closes and makes ground for that bulb it powers up the circuit which also powers up the ICU flasher giving it a signal to start flashing. This is alerting the driver that for a brief moment there was a no oil pressure condition but it has returned to normal specs. The power wire from the alt feeds the ICU with a memory wire and it will continue to blink until the car is shut down and re-started. At this point the memory wire looses it's power and stops the ICU flasher from blinking. With that being said I did some digging around in my wire harness and managed to find a bad spot in the wire coming into my sending unit which was hitting ground for a split second and signaling the flasher to start flashing. With a quick repair it's good as new. I tested it to make sure everything was working by jumping the + on the sender to ground which flicked on my oil light. Once I removed the sender the bulb would continue to flash as normal until shut down. Works A-1.

Again hondadude, my appoligies if you were under the impression that your schematics wasn't helpful. I was just confused with the differences from yours to mine thats all.

I guess you cant see the ICU highlighed in blue. Maybe its time to upgrade to a colour monitor. And, I wouldent come off soo cockey if I was asking strangers for help. We have no obligation to assist you. If your a wiring genious, and you know how the charging system works, then you should be abel to figure out what that diagram is saying.

chadnixon

Again, I was commenting on the differences from this diagram to mine. As for being cocky, if that came across that way then again I appoligize.
