Question about 2004 Toyota Sequoia
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?
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.
