2004 V35, Oil light on under braking

Hey guys,

 

I just noticed this today, but under somewhat hard braking, my oil light came on. Now I checked the oil before and it seems full, and it was full about a week ago (will check again on cold engine tomorrow morning).

 

The oil light only very briefly comes on, and goes away when stationary, it never comes on under accelerating, holding speed or normal braking, only hard braking, and if i hit the clutch when I do. 

 

The car is very low km (53000), and had all fluids changed at 52000kms, so I don't think it could be low.

 

Any ideas?

 

Thanks

 

p.s. car is 04 V35 non rev up VQ35DE

If it's not happening when accelerating dare say that you're building enough oil pressure which goes when braking.

I'd say oil pump and or oil sender unit.

Would that happen on such a low km engine, and it only happens for a second after I put my foot on the clutch while braking.

It can happen on a brand new engine. Unfortunately mass production can have some parts fail however haven't heard of these failing often.

If you're 100% sure your oil level is correct I would look at the sender (including wiring) and pump as a start.  

On a separate note when you imported it, were the Kms verified/checked thoroughly to condition etc?

Yep, full dereg and genuine kms, not worn out like a high km car, I'm going to drive it down to my mechanic tomorrow to see if he can mechanically check the pressure, its only a short drive and the car isn't making noises nor is it low on oil so should be ok i think. I'm leaning toward thinking its the sensor. 

The engine idle is dropping too low to activate the oil pressure sensor circuit and keep the light off. What is causing this low idle at deceleration/no load? Any solid or intermittent checklight Secondary O2 sensor bad? Tps/thottle body good/needs cleaning? Vqs are throttle by wire right? Coilpack failing/misfiring? What does the idle drop to? Seeing that you went through the trouble of changing all the fluids do you mind getting a new crank sensor and using the original as a spare? Oil light=car on engine not running/oil light wire short/engine idle too low(see above questions)/clogged oil strainer/very old oil/faulty or ailing oil pump(ailing and dead are the same it wont gush oil on the cams due to not enough oil pressure). If either O2 sensor is bad/very very dirty the ecu will compensate fueling and timing on deceleration wrong it would run rich and pull timing. If the throttle body or idle valve is "sick" it wont give correct air compensation on deceration. Coilpacks love to give trouble off load and idle. If ur crank sensor is on its way out on deceleration it would pick up wrong and bog. When you depress the brake and clutch pedal, individual signals go to the ecu to help with transient compensation, load to off load, off load to load etc. Hope this makes sense and helps to understand how various problems occur.

I Would agree with the others, possibly rpm dropping too low, or it could be a sender issue, if you can confirm the RPM isn't dropping below 650rpm when you press the clutch, then perhaps have the mechanic fit a pressure gauge and take it for a drive to check oil pressure figures.

    • Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4
    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
