My 00 f150 is spitting out this code i changed the o2 censor in jan. and it is spitting it out again. i assume censor 1 is the first one in line on the driver side but not positive i have 4 two each side whats the order? What could be other possible causes?

 

You probably didnt connect the plug all the way and it came lose. Get under ther and check the connection. Happened to me before.

 

Nope, it's the passenger side forward. You should post the scanner numbers.

Heater circuit Malfunction is usually a connector or wiring problem. Can be the O2 itself. Wires are very sensitive.

Passenger side harness takes a beating when the heater core hoses start to leak.

 

I believe bank 1 is the passenger side. Sensor 1 would be the upstream (closest to engine) sensor.

 

Damn jbrew beat me by 3 mins. Must of been when I grabbed that beer.

 

I'll edit that if you get me one too

 

cool thanks guys i think i will go buy another o2 today change out the driver side one i put in take it back get a warenty replacment come home and change the passenger side then i will have changed them both at once clear the codes see what happens. glad somone told me i was changing the wrong side the jerk offs at autozone told me it was driverside for sure i will change them out check the wirers and update u guys later today

 

No no, just install the old drivers side into the passenger side. Life just got easier. Well, until you try to remove the passenger side lol. You'll find out why soon.

I'll even make that easier 4 yuh. Start off by removing passenger side wheel/ then inner fender liner/ then O2.

 

Yeah and good luck getting the o2 connector apart.

 

weel guys gave up on my original plan just bought a new sensor came home took off the old installed the new. A lesson i lerned last time (there is no subsitute for a 22mm wrench) just reached up next to the heat sheild from under the truck got the wrench at just the right angle (open end) broke losse with one grunting push. Stuck a small flat head up into the conector under the latching top piece pushing down the latch itself thats on the bottom piece grabed the wirers about an inch away from the conector and pulled bottaboom bottabing in and out done in ten minutes. Never did take it back and try to claim warranty on the one i bought a few months ago would have fet good to take it to the man

 

Your good, I can barley see mine from the bottom, let alone get a wrench on it. You can't have a 5four.

 

yup 2000 5.4 106000 on her
should be able to barley get a wrench on from under i guess it depends what year truck as to positioning
