Low Oil light

Thank you everyone. The Mechanic just towed it to the shop. I hope it’s just a sensor.

 

The CPS signal wouldn't directly effect the low oil light, but for whatever reason the trucks with bad CPS were getting low oil light warnings and trans over temp warnings and other non related warnings. The one thing that was universal though was...never any code showing a bad CPS. Early victims had their trucks down for days/weeks because the techs couldn't find the problem and several reported that they informed the dealer/tech of the CPS issue only to be blown off.

Critter chewed wires is entirely possible. Yeah Soy based insulation is beyond stupid, but blame the wire manufacturers, no auto mfg wants it. Clogged oil pickup not likely on low mileage engine running synthetic 0w-20

 

My old 5.0 explorer would warn you of low oil level or pressure. I saw it for the first time at 200K miles. The display would say low oil level and crawling under the car you could see the sensor in the pan. Think it's pretty common.

Most newer German cars don't even have dispsticks for the oil. The computer tells you the oil level and you add/remove it based on what it says.

newer BMW, MERCEDES, have an electronic level monitor, but the engine has to be to operating temp, some AUDI's have a dipstick tube, but no dipstick my old shop we used one from an older VW PAssat I think. love oil changes in a MERCEDES.. have to suck the oil through the dipstick tube, land rovers were funny, the oil fill cap has a tube that runs down into the oil pan to suck up the oil using a vacuum machine.

 

@SteveS197 Keep up posted on what you find out. Thanks

 

My 1999 Porsche Boxster had an Oil LEVEL indicator. Just like a gas gauge. When you turned the ignition to accessory it would give you a bar chart. 1 bar from the top was about 1/3 a liter

 

What he said, @SteveS197!

 

My wife's BMW doesn't even have a dipstick, only way to check the oil level is through the computer. Gives you a little bar display but the bad part is the engine needs to be fully warmed and it takes about 60 seconds while running. Some good that will do you if you are a couple quarts low...

 

The mechanic said it’s the oil filter housing. He’s picking up the part from Toyota in the morning. I’ll speak to him tomorrow morning on my way home from work, but Isn’t that covered under the warranty?

 

No Crap Eh!!!! At least Porsche it had a stick and the car needed to be off for a couple minutes.

 

Be sure to get a full explanation on how the filter housing set off a low pressure light. And how he was able to diagnosis that.

 

Who did the last oil change and when was it done

 

My guess is leaking oil and the level dropped to low enough to drop the pressure. Hopefully I’m wrong

 

Checked right after he shut it off?

or let sit to get an accurate reading

 

If you don't have a Toyota service doing the work, you're on your own.

 

I guess Toyota will work on my truck for now on. Sucks that my Toyota dealer is a bit far from me. Thank you guys for all your help.

 

New Supra doesn't have a dip stick either. It does have a BMW engine, so that's what ya get.

 

I was just thinking. After this fix, should I bring it to Toyota for them to check his work, making sure it was done properly. I drive my Truck cross country regularly. Or maybe have them do a service on it and see if they say anything about it.
