Ya I tried letting it cool, 5 minutes, 15 minutes, 30 minutes, didn't help. The start measurement was still available after 30 minutes and it still failed. I tried every suggestion in the manual, in forums, even tried AI. No good. Thanks for the info though.
I was having same problem, 2020. Did some research and turns out the oil can be too hot to measure as well as too cold. I had to turn my car off let it cool for a bit, then turn it back on and it worked just fine. I thought I needed a new pump or sensor but nope, all fine.
The new pumps part number supersedes the old one so dealers can only order the updated one. I didn’t mention anything about online stuff even though I knew the oilpump would fix it I just let them do there thing.
Tell the dealer its a well known issue with the oilpump and it's failure mode anyway but they won't believe you. They'll want to replace the oil qty sender unit first and when that doesn't fix the issue then they'll go with the pump. Just the way it seems to work with dealers, ignore the...
...just tell them that the oil level check fails and then they'll just figure it out or should I mention I read online it could need the upgraded oilpump or new sensors?
If that's it and they replace the oilpump, would they replace it with the same plastic one or is only the metal one...
The earlier models used an oilpump with plastic internals. Updated one has metal internals. Early signs of failure are being unable to measure engine oil and eventually oil pressure issues and then worst case total oilpump failure. There’s a lot of similar posts on here with the same issues...
...had the plastic adjusting ring, but it is not broken. From what I seem to gather this is more of a cold-weather problem? This is the first oilpump sold (through the Toyota network) in my entire region here in Texas.
Here is the part # for the new pump, which did have the steel adjusting...
If you want no risk, then that'd probably be a safe choice. I like to roll the dice on stuff and just kept driving the car and taking it easy though and nothing happened for me other than the code on pulls and occasional high oil pressure in light throttle. razorlab has a chart that can provide...
If you account for ambient pressure, those pressures that @MacAllan30 posted are within spec except for WOT which is about 10psi higher but nothing to really worry about.
He is in DFW so approx 600ft = 14.4 psi
35 at idle - 14.4 = 20.6
50-70 part throttle - 14.4 = 35.6-55.6
90 at WOT - 14.4 = 75.6
I'm very hesitant to drive the car until the pump is replaced. Someone also recommended to replace the oil sensor as well in the pan. This B58 oilpump video came out a few days ago and explained that the springs are different on the updated oilpump in addition to the plastic being replaced.
If the car is has a tune on it, the tuner could have changed the target oil pressure as I've been told.
Although, if you have no tune or the tune still targets stock oil pressure, those values are higher than normal. When my pump had issues and I couldn't measure oil level, on hard pulls I was...
In BimmerLink oil psi was 32-35 at idle, 50-70 part throttle, and 90+ on a hard pull. I’ve gotten the message that engine oil is unknown each time I start the car. Testing for oil level fails each and every time. Picked up a new oilpump from FCP Euro for $550.
A dealer principle selling an oil burner, perish the thought. If it was an oil burner he'd keep it forever until he died before he'd flog it off to some poor suspecting sap. They are after all men of immaculate principles and of the highest integrity you can trust with your life are dealer...
I was a little nervous but. ….as you run the risk of a poor run in though. I figured as mine was previously owned by the dealer principle, he wasn’t going to on sell an oil burner. Made good power on dyno. Makes better power now! I’ve now spent the same money as brand new and I have close to...
Ironically, the day you posted this comment was the day I was finally able to bleed my clutch after removing the CDV. I also had issues trying to use a Motive power bleeder. Initially, mine was leaking out of the box from multiple places. I tightened all the joints and all seemed well. I was...
