Hi,

I have 1994 Honda Civic HB DX (D15B)

Engine was baught fall of 2007 to replace oem. A year after (Jan2009), transmission broke as well. Car has sat for couple of months while searching for a good working transmission (MT). As of Early May 2009. Found a MT trans and installed it and put everything back together. I have started the car up and it ran nicely. test drove it down the street, back and forth. My Oil light has come on when i did the first start up and has been on since. it would flicker randomly and stay on. 3rd week of May i really did a test drive to see what i can come up with.

Ive check oil level and they are good b.c. i have not done anything to the engine since the trans had broke. but i did drain engine oil and filled back with proper level but same symtoms.

What do you guys know and what can i do on my own before i figure out it may be the oil pump or something.

Let me know. thanks

 

change the oil pump n sensor...do both...

 

Could be gunky if it's been sitting.

Maybe there's a blockage, or the pump/filter is bad.

 

Replace the sender, it's easy and cheap. Also check the wiring that connects to the sensor, because that might have got damaged in the course of the transmission swap.

I'm assuming that you didn't have a sudden oil pump failure upon first startup after the car was just sitting there waiting for a new transmission, so the only other thing I would check is a clogged up screen on the oil pump pickup.

Really though, after you've checked the condition of the wiring, and you've replaced the sending unit, and the problem isn't fixed, take it to the nearest shop (tow it?) and get the oil pressure tested (or get someone to come to you). If you truly do have a mechanical problem such as a worn/broken pump or a bad bearing, you are risking a major engine failure by driving the car.

 

Where is the Sensor for that and what does it look like on the car?

 

What does the Sender unit look like and where is it located? where would that wiring sensor be located at? Before the car sat for couple months waiting on new tranny, no problem with oil. Ive been trying car with light on for almost 100+ plus miles now. Im guessing that is a really bad idea.

 

The oil pressure sensor (sender) is normally next to the oil filter... or above the filter. It is has a single wire over it. It is the same fitting that most turbo guys take off or T off for an oil feed. Google the picture.... I'm sure there are pics of it..... Also, check that wire.... it may be loose or disconnected....

 

Thermal, Thanks. i will have to look at it in a few days. too busy.

 

Bumpping for the night. if anyone else has any answers to help out, it is always welcome. thanks

 

any other answers would help, anyone?
