    This morning the check engine light came on. The codes on Torque Pro are PO101 and PO172. Is it okay to drive it the 60 miles to the dealer? It's already scheduled for a service appointment for normal maintenance Saturday morning.

    Yeah you're good. It's an air flow sensor code and a fuel rich code (O2 sensor)

    S62 Pro ?

    Thank you.

    Not an S62 Pro phone. I put Torque Pro on a Motorola One. All posting is done on my desktop computer (an Acer all-in-one).

    Looks good. You should make a thread/sticky so that everyone else can attempt that fix as well.
    Too bad I'm not down there visiting on the other side of the river, would be a good excuse to explore Laughlin a bit more, as this could be a fun fix, and way more entertaining than getting pulled over in Searchlight for speeding.

    Here is the workup for DTC P0101 : https://share.qclt.com/%E4%B8%B0%E7%94%B0%E6%99%AE%E7%91%9E%E6%96%AF%E5%8E%9F%E5%8E%82%E8%8B%B1%E6%96%87%E6%89%8B%E5%86%8Cpdf%E6%A0%BC%E5%BC%8F/Repair%20Manual/04pruisr/05/2054m/cip0101.pdf

    For P0101 : you might try cleaning up the MAF sensor with some MAF cleaner, could be an easy fix.

    Here is the workup for DTC P0172 (and P0171) : https://share.qclt.com/%E4%B8%B0%E7%94%B0%E6%99%AE%E7%91%9E%E6%96%AF%E5%8E%9F%E5%8E%82%E8%8B%B1%E6%96%87%E6%89%8B%E5%86%8Cpdf%E6%A0%BC%E5%BC%8F/Repair%20Manual/04pruisr/05/2054m/cip0171.pdf

    Do you have techstream, or could you post the long/short fuel trim readings?

    How many miles on the vehicle?

    Miles in my signature: 183,000.

    Thank you for that but I'm not really a DIY guy when it comes to cars. I change the air filters myself and do a few other things but not much.

    I only loaded Torque Pro again yesterday morning when the light came on. I had it on a previous phone but hadn't loaded it on my current one. No Techstream so I don't think I can provide long/short term readings unless the car stores that information and you can tell me how to get it.

    The 180,000 service was due in November but the cash wasn't there. I had them do the oil change and I changed the air filters but had to wait until now to get the rest of the service done. I already had the appointment scheduled at Anderson Toyota tomorrow for that. Just a coincidence that the check engine light came on at this time. My thought is to have the dealer take care of that while they're doing the rest of the service.

    I know the dealer is more expensive but for a major service I know Anderson will do it to Toyota specs. They always try to oversell so I'm cautious there but they do stand by their work.
