Tire Pressure Warning Light - Dead Sensor..

Thanks for that information! I really appreciate it.

As my journey continues.. I just went back to the dealer this afternoon and they did indeed replace the TPMS Receiver (ECU). I'll let you know if any other trouble arises.

 

Hey there everyone, it has been brought to my attention that I have no updated this thread in quite some time. Sorry about that! However - ever since I got the TPMS ECU replaced, I have had ZERO problems. Everything is working absolutely perfect. I figured that was the issue all along, and sure enough, it was. If you have this issue - I suggest they switch the ECU first - as they replaced sensors on my tires and that didn't work.

 

I didn't ask. The dealership is always really busy and all. Oh well. They only replaced the right rear sensor anyway.

 

Bumping for another update - On Saturday night, Aug 21, the light blinked for a minute, and stayed on for a few minutes. I was doing slow city driving, at night, and the temperature was around 75. The light went away after about 5 minutes of driving. Think this is something to tell Toyota about once again? Or should I live with it? Your opinion is appreciated.

 

They called me about a week after I got the ECU replaced, and I told them everything was fine. However now this occurred. Looks like I may have to start from point 0. I kinda wish they would offer me some type of compensation for having to deal with this repetitive issue.hwell: I'll call them up and ask for a case manager.

 

I sure have, all pressures are as they should be. Also - if it WAS a pressure problem - the light would just come on and stay on. As stated in the manual: when the light blinks, then is staying on it's a malfunction in the TPMS warning system.

 

Sure seems like I have one, doesn't it? I updated my case on this whole issue by calling my case manager at a 1-800 number. She had the dealer contact me, which they did (yesterday). They told me to bring the car in anytime, and my service rep would be there everyday except for Wednesday. I said alright, and that I would bring it in sometime soon. So, I got up early on my day off (Saturday) and my service rep is NOT working. So I told another rep what was going on, and he said it's not going to be worth waiting on today - because there isn't much they can do. He said they only have 2 diagnostic technicians on staff and that I should call to schedule an appointment after they have done more "research". I then drove 20 miles back home, with nothing done to the vehicle.

I'm going to call the service rep and tell him that if I'm going to bother driving my car out there the 5th time - and it comes back still not functioning properly, they can say goodbye to my business. Wish me luck. This is pissing me off.

 

Light came on again yesterday night - sorry to bump - I'm keeping a log for myself.

 

Nope Paul, hate to say it but I don't have a resolution. It rarely happens though. I think the last time it happened was about a month ago. Seems like every month or so it happens. It doesn't always occur at night either - I tried one last time to meet up with my service adviser who has been with me through this and he told me he would be at the dealership everyday except Wednesday. So, I went Saturday and sure enough he wasn't there. I explained my long journey of problems with this TPMS system to another adviser and he basically told me that Saturdays are not a good day to diagnose my car because they have near no techs back there on Saturdays. So, I walked out and left. Next time when I go in for an oil/tire rotation I'm not going to leave till the problem is solved. I love the car, but this problem really pisses me off.

 

Exactly! The very first time I went in they told it was my tired pressure - adjusted them and sent me on my way. Sure enough, I knew pressure was not the problem and ACTUALLY read my car's manual unlike the service people there do. I am going to do that and get back to you all. Hopefully we can get this sorted, because it wasn't even the TPMS ECU - because it's still happening. What else COULD it be? Seems like they were just replacing parts in hopes the problem would be gone. I'll reply to the thread once I get in contact with Toyota and get my error codes received. but, wait - they'll probably say that there isn't any! Do you know how long the error codes are stored in the TPMS ECU? Because, these two occurrences of the light happened 1 and 2 months ago. Think they will still be logged?

I'll probably just drive to the dealer and see what they can do for me. Who knows how that is going to turn out though..


Thanks for the advice and support to you both! Thanks again guys!
