P0031 and P0051 Codes - Check Engine Light, VSC TRAC, VSC OFF Light - The Track Ahead
Hey
Though its an old thread, am having the exact same issue on my 2005 4.7L v8, changed the bank1 sensor1 O2 sensor(denso) still having the same code & VSC lights ON. Wonder how you got rid of it.?
Hey folks
Had a P0031 code, bank1 sensor 1, it was one heck of a job to reach it with a wrench, as i didnt want to buy the special socket ($15 or so),cut the wire harness at the sensor for the socket, cut a 22mm long socket to desired size & removed the sensor. Put a New denso sensor &connected...
Its a Great product that i lean to use time to time, Have used on Yamaha bikes, Camry, CRV, Tacoma, 4R and all kinds...You could literally see the rpm guage move swift if it was sluggish to start with.
Its a Great write up !! Obviously more so for the later 4th gen where there is no dip stick. But IMO an electric pump connected to Vehicle 12v and to the tranny cooler lines would do the job faster & never have to go under the truck so many times...check the link blw for the pump sold in amazon...
