DTC P0161
DTC P0134
DTC P0135

i took off my cats and removed the rear 02's, thats the 161 code(i searched). whats up with the 134 and 135. bad front o2's?

 

DTC P0161 H02S Heater Performance Bank 2 Sensor 2

DTC P0134 H02S Circuit Insufficient Activity Bank 1 Sensor 1

DTC P0135 H02S Heater Performance Bank 1 Sensor 1

 

so 135 means the 02 doesn't work. what the hell does Circuit Insufficient Activity Bank 1 Sensor 1 mean? wires messed up?

 

when i had that code come up it was a bad ground. but i replaced my o2 and they all went away

 

i still got the two from the rear. ill switch them out and go from there. thanks man

 

have you done any exhaust work recently?

 

yeah when i put the new engine in i put mid-lengths and took off the cats with a custom y-pipe. then i installed the front 2 02's and unplugged the rears. i know i got to get the rears turned off (witch is the 161 code i think)

 

if you broke one of the wires in the 02 then it will throw those codes

 

Yea, sounds like you either have a bad front bank1 O2 sensor, or the wiring to the sensor is damaged...check and make sure that none of the pins are backed out of the connectors and that none of the wires are broken. If that's OK, then more than likely the O2 sensor is poop.

 

ok sweet, i will be checking it tomorrow. work sucked today so im just relaxing tonight
