  1. Oil Pump Control Valve before Oil Pump Warranty?

    Take it to another dealership and try again, don't mention you visited another dealer prior. I got my Oil pump replaced under powertrain no questions asked. They saw the oil pressure was inconsistent and authorized replacement. ( I have a thread posted about my process and experience) Took me...
  2. Oil Pump Control Valve before Oil Pump Warranty?

    I have a 2021 and am having the issue with oil level not measuring, which everyone says is likely a failing fuel pump in the forums. Toyota says they’ll only replace fuel pump under warranty after trying to replace oil pressure control valve first, but that’s no longer under warranty. Anybody...
  3. Oil pump tsb?

    I guess that's hard to say but it isn't a totally comfortable situation. Apart from the extra power to drive the pump there could also be issues with the pumps drive longevity. Things aren't necessarily designed to work at maximum output permanently. I think if I had an affected car and not...
  4. Oil pump tsb?

    So how long can we technically "live with" the default high pressure scenario before it becomes detrimental to the engine? Until the CEL comes on? Not being able to measure the oil is annoying but not scary since I haven't burned or lost any oil in my 5 years of ownership and do religious oil...
  5. Oil Pump

    Yikes! Thanks for the codes. Dealer this morning won’t do anything because no codes. And my warranty expires in 2 months. FML. Thanks
  6. Oil pump tsb?

    Nice tack to take. I used that when I uploaded a failure video to the complaint site. Told them I paid $94 for diagnostics and the failure mode was not fixed. Let’s see. Thanks for the pro tip!
  7. Oil pump tsb?

    Then tell them to fix the issue of it not reading oil level. If he won’t jump to replacing oil pump. He can’t just ignore the oil level reading not functioning. Take it to another dealer lol. Shit tech right there. even tho the other Supra tech at the other dealers may be the same
  8. Oil pump tsb?

    The pump has a failure mode that defaults to high pressure, not no pressure so the odds are in your favor.
  9. Oil pump tsb?

    Interesting. I’ve tried mine from cold start after short drives. Doesn’t matter - at least for me. But I’ll try that. Thanks! yea, it’s going back tomorrow. We’ll see what they say
  10. Oil Pump

    for me it was an "1C0101 engine oil pressure regulation" code for a long time, then simply "1C2001 oil pump" when the CEL came on. 2021, 35K miles. failing to read is almost always an indicator that your pump is in the early stages of failure. Could go a year like mine did before actually...
  11. Oil Pump

    Any information on the code it throws? Mines not gone yet, just failing to complete read. 7/20 build also, only 25K miles
  12. Oil pump tsb?

    I wouldn't be relying on that assumption for the the continued viability of the engine. A check of the engine oil pressure scheduling would be a wise precaution. Phil
  13. Oil pump tsb?

    ...cold start and idle for 5-10 minutes and as SOON AS the "measure oil level" was selectable, I measured oil. It works for me, I dunno why, but if I drive anywhere longer than 10 minutes it doesn't allow me to measure oil. Weird, but I think potentially a software bug rather than a failing oil...
  14. /3.0 and 3.0 why?

    ...and 2.0 Liter. Possible mistype? The major differences are 2 port (earlier models, 2020) vs 6 port (2021+). There's a few other smaller differences like plastic oil pump internals on the earlier models vs metal on older. I'm sure someone has a more complete list, but those are the major ones.
  15. My New Final Edition

    So just mess with the settings for steering and put it back to sport/ normal mode ? Please explain . Thanks.
  16. My New Final Edition

    ...steering from sport back to normal. Issue solved. Maybe try that. If you do have a warranty issue, find a dealer who has a Toyota dealership and a BMW dealership. That's what I did when the oil pump failed on mine. The Toyota dealership had the BMW dealership swap the oil pump, all under...
  17. What did you do to your Supra today?

    how many miles?
  18. What did you do to your Supra today?

    Oil pump is finally replaced and we're back to normal.
  19. Can't measure oil - have updated oil pump (WAA03)

    ...of time it establishes that the oil pressure is within certain parameters and then measures the oil Qty? If this is the case then when the oil pump adjuster ring breaks/fails the oil pressure defaults to max oil pressure which is above the pressure parameter for oil level checking so you get...
  20. Can't measure oil - have updated oil pump (WAA03)

    That's about $2388 US dollars which is about right. My dealer said it would be about $2500, but luckily I got mine replaced under warranty. Zero cost to me, just didn't have the car for 2 weeks. Glad you're fixed up. Enjoy.
