2003 Sequoia SR5 207K miles and this morning after driving about 60 miles in town the 3 Dash lights came on and stayed.

This is the only dash lites to come on in 6,000 miles.

This is my first Toyota and it has been dealer serviced records online since we bought it back in December 2019. Dealer serviced for 120K miles exclusively.

Any help would be requested soon,

Thanks

You need to check the code. If you don't know anyone with an OBD2 scanner than you can go to an autoparts store and they'll typically scan it for you. Generally, when the check engine light trips it also illuminates the VSC and trac lights.

This is a pretty well-documented issue with lots of different solutions (some quite easy to not so much). Mine has been doing this for years and I have finally bitten the bullet to get addressed, although mine was traction and brake lights. My mechanic diagnosed the problem and has suggested I replace the master cylinder. It's in the shop getting replaced now. Will report back on its success.

Mine really never caused major issues. However, the other day the lights flashed when I was driving down a hill and the wheels locked up. With young kids, I just couldn't have that happen. The car otherwise is in great shape with relatively low mileage for an '04 (180k). Mechanic quoted me ~1300 for the repair and figured I'd replace it and drive it for another 4-5 years rather than buy a new car.

Did you get any specific check engine codes for this brake problem? The lights pretty much stay on in my truck but it's for an evap emissions leak. My municipality does not require an emissions inspection so I've just let it be. I keep a blutooth OBD2 reader in the truck and check it from time to time.

Check the codes. If no codes. Check the gas cap. Code readers are 15 bucks and can save you tons.

I just had the CEL, VSC, TRAC lights come on. The 2 codes reported were both EVAP related (P1440 and P1456), and I suspected the gas cap, which didn't seem to tighten down very well. I replaced the gas cap, and after clearing the codes with my scan tool, the issue has not yet returned. Hopefully the codes reported for your Sequoia are as easy to resolve as a simple gas cap replacement.

OEM Toyota gas cap was the first thing I tried. That was probably a year or more ago. My research says that there is a solenoid in the evap system near the gas tank that goes bad. Apparently, it is replaceable but I've got more pressing issues on other vehicles that take up my DIY time.

I heard and read a thousand reasons why these light all come on at once, my solution after running a OBD scan and getting a code P0051 "(Bank 2 sensor 1) heater current is low OR (bank 2) heater current is low" an oxygen sensor replacement. That took care of it at once. Have autozone, a friend or something run a scan for you, get the code and fix the problem

@farlo001 any update on how this worked out for you? Doing this tomorrow. Thanks

Same lights came on again today, got code P2442 on scan. Likely fix is replace air injection pump to the tube of thousands is $$! Starting to regret buying truck. It’s turning into a money pit!

Went to see my preferred auto tech re this issue. He said this problem code is THE most referenced code! Evidently Toyota knew there was a problem with this because they extended the warranty by 10 years to cover this issue, but that expired in 2018-which puts my Tundra past the warranty period!

It would cost thousands if you replaced with oem but you can spend a quarter of that purchasing a bypass kit from these guys. Cant remember his first name, but this guy is on here fairly regularly so either shoot him a pm on the thread below or just call their 1 800 number listed. Pretty sure a bypass is around $400. Not cheap but way less than what you were thinking.

Bummer... I luckily haven't had any lights or codes stored for a while other then the ones that are seen on the Toyota scan tool only. Still hoping this will fix my issue with the trac

If I’m reading the literature correctly this bypass kit is for off-road & competition ONLY. My Tundra is a daily driver, on-road only. Not sure yet what I’m going to do!

 

[NeedsMoreTorque]

When you check the codes, you want to get the ABS error codes too. If you use one of those inexpensive ODB2 readers with Torque or a similar app, you can get codes but NOT the ABS codes. I ended up buying a special cable and getting Toyota techstream running on a laptop to read the ABS codes. Just an FYI as it is confusing.

The cable I got is a "Toyota MINI VCI J2534" and you can find them on Amazon/AliExpress (long shipping)/eBay/etc.

I think you misunderstood. It has nothing to do with off roading or competitions. These things simply bypass the AIP's which is whats failing on your truck. Your code is P2442 which is switching valve stuck open bank 2 and is one of the codes a kit can eliminate. Again, up to you but you can either spend thousands on new oem parts or give them a call, at no cost to you, and see what they can do to help.

If the check engine light comes on, the Trac Off and VSC Off lights always come on too. At least they do on my Sequoia. When I check the codes, it's been different things, from the gas cap being lose to a cracked vacuum hose (paid $3 for a new hose length at AutoZone and fixed it in 5 minutes).
