Hey all,

Got the dreaded wife call. CEL light on in the landy. o'reilly's pulled the codes for me. Here are three pics. There are three codes:

1) P0036
2) P0054
3) P0136

Any thoughts on this. Assume it's an o2 sensor?

We have an extended service plan on this, but want to make sure it's covered b4 I run it 45 miles into Tacoma LR dealer.

Thanks

I believe these are just O2 sensor codes and there is a tsb about them. Should be covered under your service plan.

I get one that pops up every 6wks or so for bank 2 sensor 3; no drivability issues and not sure what triggers is, but I clear it and it stays gone for another month or two.

Just called the dealer. Said they are scheduled out to July. ***. July. Might as well be July of 2023 for that matter.
I just can't believe this crap. Of course you have to freak out for them to try to do anything. Feel sorry for the poor advisors who have to manage through this.

I doubt o’reilly’s cleared them, I know others don’t for ‘liability’ reasons, but I would do that and see if it comes back. May just be a flukey trigger. Any chance it was raining, puddle, or car wash recently? I think the tsb mentioned or I read somewhere where cold water on hot sensors will cause a trigger

No, they did not clear them. No rain and no puddle or car wash according to the boss. It is time for it's LOF and the dealer has agreed to take it in and work it into the schedule somehow. WE are off on spring break so I hope it's done by the time we get back.

Our new Mach-e is being built on May 2nd, so maybe our landy thinks she's being replaced and is just acting up?

I believe this is your mid-catalyst sensor. Pretty easy to get to. If you don’t want to wait for the dealer, you should be able to go to an indy with the extended service plan (I don’t think they require the dealer to do it). Replacing the o2 sensor is pretty straightforward, so any mechanic can handle it - no need for dealer expertise. You could even diy if you were inclined, but I understand the desire to make use of your service contract.

The TSB suggests that water can contact the heating element and cause thermal shock. Since the heating element is inside the pipe, they must be talking about interior condensation (before catalyst is hot enough to evaporate). I don’t see any other way water would get to the hot sensor surface - puddle/car wash would not do it.

thanks, you are probably correct. Good news is the dealership is going to shoehorn me in. I am going to drop it without an appt and they are going to "find time" to make it happen during the week. Huge props for the dealership in Tacoma.

Talked to my regular guy today and he told me they were struggling to find techs. He said no one wants to turn wrenches anymore. Isn't it high time we start pushing technical trades in high school vs. college as an option? What I see is kids going to college who should be going to trade school and end up either dropping out or passing with lower grades and end up in a $30k a year dead end job. When, they could have went to trade school, became a tech and be making six figures. We definitely have to do more to promote these jobs. My nephew with a high school diploma went the tech route. He makes over $100k a year. For a 30 year old with a wife and 1 kid living in the middle of nowhere, he's killing it. Okay, sorry for soapbox rant.

Absolutely agree. Just going through the college thing now with one of my kids. It’s nuts. The prices, the demand, the overcrowding at some schools. Meanwhile skilled trade rates seem to be skyrocketing with no end in demand to be seen.

Skilled trade rates are skyrocketing because the cost of the materials used by the trades have doubled, or even tripled in many cases over the past 1.5 years. Oh, and all those guys that work for the skilled tradesman still want to be able to afford a loaf of bread and gallon of milk, so you need to pay your labor force more, as well.

I have been in the electrical trade for about a quarter century, and I have never seen anything remotely approaching the situation we are in now. Only thing keeping me working is I have one more daughter to put through college. If not for that, I would have already said "**** it" and retired. I need 6 more years to be done, but I might be living in the back of my LR4 by the time I get there.
