Just bought a 91 DA for my friend and the oil light keeps on flashing. The last owner told me that the oil was low but after we did a oil change, it still flashes. reset the ECU and disconnect the battery but nothing seems to work. The car runs fine but I don't want to miss anything up. Are the oil pressure sensor bad? Any info will be helpful.

 

Forgot to mention but there is no check engine light or cel code from the ECU.

 

either the pump is going bad.. or the sensor..

when do u get the light, when you're turning, hitting the brakes?

It actually starts flashing as soon as the engine turn on.

 

Anyone else?

 

wow another person with this problem...i have the same issue...mine wasnt the sensor or the pump...what i did was installed a new gsr oil pump,and took the sensor out and just installed a oil gauge 16 bucks..i hate gauges but i bit my lip and bought one...just as a test hook one up and if u got good oil pressure ur fine.if not then change the pump...

 

I had this problem several years ago, oil light flashing when car was on. At the same time, the battery light would come ON when I turned the car OFF.

I did extensive study of the wiring diagrams in both my Helms and Haynes manuals (it's a good idea to have both), and found that the only thing in common between the oil pressure sensor and the charging system was a connection to the alternator.

I ended up replacing the alternator, and both problems were fixed.

Weird I tell you, weird stuff can happen when there's a problem with the charging system.

Cool, thanks for the useful info. I'll tell my friend and try it out.

Yeah I was a little confuse when I 1st saw the light flash even the oil level was at the right point.

Once again, thanks for the info guys
