2004 Sequoia. VSC TRAC, TRAC OFF, and Check Engine lights are on. I got the P0031 code which is the bank 1 sensor 1 heated O2 sensor. 1) If I change the sensor, will the lights go out? 2) How difficult is it to change this sensor?

Re: 2004 Sequoia. VSC TRAC, TRAC OFF, and Check
It is not hard to change the sensor, it just screws into a threaded hole. The light will not go out immeditaly, after the sensor is replaced. It needs to go thru a drive cycle. Your best bet is to replace the sensor and get the code cleard by whoever scanned it for the 0031 code.

Yes the O2 sensor preheater problem will turn on the VSC light, see the complaint often, why? don't know .P0031 TOYOTA - Oxygen Sensor Heater Control Circuit Low Bank 1 Sensor 1 In most cases the O2 being replaced cures the code but here is the full story. Possible causes- Air-Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 circuit open shorted to ground - Air-Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 circuit poor electrical connection - Faulty Air-Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 circuit - Air-Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 circuit fuse - Faulty Engine Control Module (ECM)
It's probably an O2 sensor. I've had the same issue with O2 sensors failing. Go to Autozone and have them read the code or buy a code reader for $40-60 and read the code yourself... it will tell you which one is bad.
I have a 2004 sequoia with the same problem. VSC TRAC, TRAC OFF & brake light comes on at the same time. Sometimes just the brake light and other times all three. Sometimes no lights. Does anyone have a fix?
Hello. Many times the check engine light and VSC and trac are all on due to one or more bad sensors as opposed to any serious trouble. Begin by having your car's computer scanned. AAMCO transmission shops now offer a free scan as do some auto parts stores. Begin with that. Joe
please rate my answer as very helpful thanks.
The computer turns your traction control off when it sets the check engine light. Thats why VSC lights come on at the same time. Have the local parts store see what code you are getting to find the problem.
You have to know what code is stored to fix the problem. Toyota's will generally display a Check Engine light, VSC and TRAC light all at the same time, even if it's a simple problem with an oxygen sensor (for example). You can disconnect the negative battery cable for a few minutes, even though you should a scan tool should be used, to clear out the code.
