turn off oil pressure light

[maplemaf]

does it possible to turn off or down the oil pressure before the light turn on

I think what you are asking is, is it possible to lower the pressure that trips the oil pressure warning light on your dash? If this is correct why would you even want to do that? It is set at or even slightly below the minimum safe oil pressure at idle from the factory. If my oil light was flickering at me I would first want to find out why I have reduced oil pressure and fix it, not necessarily set the light to turn on lower. Maybe more details are necessary or maybe I am not understanding your post? Please provide further details so we can help answer your question.

interesting thought. I think the switch is just a hobb switch however and is non-adjustable.

I know how to turn it off... add more oil or remove your oil restriction

What R/TErnie said. It's just like a 1g or 2g DSM; there's a pressure switch (in our case, on the side of the block, rather than on the oil filter housing) that just feeds the idiot light in the dash, nothing special, and definitely not wired to the ECU. To quote the manual on what your oil pressure should be:

At 3,500 r/min: 294 − 686 kPa (43 − 100 psi)

Page 12-4 and 12-5 of the FSM. If you're outside that range, the idiot light will be turning on; and, if you're outside that range, you likely have a serious problem that you shouldn't be hacking around by disabling the idiot light. I see from your other posts that you're trying to disable the knock sensor as well, you're REALLY taking the wrong approach to this. Unless you're trying to sell the car, and make it look like it's all good?

(Sidebar: Interesting that Mitsu thinks 4.2 psi is enough for idle, though. I'd never actually looked it up before; that seems incredibly low to me.)

Is the car functioning correctly? What weight oil are you running ? There is a reason it's on...

i just want to sell the car and at idle the light flash a little bit
i will put 20 50 oil if i cant change in the ecu
and i dont want to buy an oil pressure switch
the car goes fine

Wow, I was making a joke with the "unless you're trying to sell the car" remark, but that's actually what you're doing? Your previous posts about disabling the knock sensor look even worse in this context: you're going to sell this car to someone with a quick hack around a problem like low oil pressure (and likely a disabled knock sensor) without disclosing it to the buyer?

That makes you a connard, and you'll get no further help from me. But, good luck starting that car in three or four months in Quebec with 20W50 in it.

the car goes fine but i spend enough money in that car
i will sell the car with a lower price
dont panic
i will take the pressure tomorrow for you

Thats nuts...

Buy a new sensor at the auto parts store, the sensor is the same as those in the base lancers. They are only 5 or 6 USD.

[maplemaf]

i change the sensor and its ok
thanks

These aren't $500 beater cars. Some people bust their asses to make enough to afford one and I'm sure nobody really wants to buy an engine for a car they just dropped a load of cash on. If the car isn't functioning correctly, be honest and sell it as is. Don't rip someone off for large sums of money by lying about the condition. Thats a pretty lousy thing to even think about doing.

^+1 This. If you sell it with just hiding the oil pressure problem than you sir are a scam artist. I consider you no better than those who scam people out of money here on the forums... Spend the money to fix the CAUSE of the problem and sell the car legitimately.

The sensor is set to illuminate at 4.6psi and below.
