Codes 1998 5.4
 

K my tuck pulled 4 different codes any help is great.
1. P1152 (lack of H02S21, swithches sensor, indicates rich)
2. P0155 (02 heater curcuit, Bank 2 Sensor 1)
3. P0153 (curcuit slow response, Bank 2 sensor 1)
44. P1151 ( lack of Ho2S21,swithches sensor, Indicates Rich)

Pretty self explanitory. B2S1 ranging out. Getting old. Resitance in the o2 circuit is failing

k might be a stupid questioon but how do I go about fixing it ?

Replacing the bank 2 sensor 1. Pretty sure it the passenger bank upstream o2 sensor (before the cat) 22mm wrench or oxygen sensor socket will work

Nope, bank 2 is driver's side.

thanks glc ... wasnt 100% sure ... i am so used to all cars being different becasue i work on them all day long lol
