Dash lights?

[ToyNutt]

Yesterday I was coming home from work and stopped for some gas. When I restarted the motor the engine, abs, and traction control lights came on. I don't notice anything different but they continue to stay on as long as it's running. Any thoughts?

The gas cap isn't on fully.

 

[ToyNutt]

That was the first thing I checked, it was on tight.

 

[GottaBeTRD]

sorry to question your definition of "tight" but did the gas cap click tight?

 

[ToyNutt]

Yes I always tighten it untill it clicks

Year?
Engine?
Mileage?

Time to find out which P code is stored in your ECU.

Whats the cheapest/easiest way to do that?

Take it to Oriellys, Napa, or any of the chain auto parts stores, they will tell you the code for free.

With your mileage, I am guessing front A/F sensor in the exhaust. But you'll have to get the code.

just got it checked, code P1135, A/F sensor. Maybe a short circuit or bad connection. Any help as to how to fix? Where is that sensor located?

Read attached for bank 1 sensor 1 location.

Google "p1135 4Runner" for a ton of reading material.

The code is for the heater circuit in the A/F sensor. It could be the wiring but they seem to go between 100k-150k miles.

Do you know when it was last replaced? Likely it just needs replacing. If so, look on Amazon for Denso brand.

 

[ToyNutt]

Thanks for the help guys. I think it's the original so I'll probably just replace it. Any thoughts on how much they run?

 

[notrayray]

Yes, I forgot to say to get the correct Denso sensor.
