P0135 O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)


Just double checking if thats the one on the headers?


would this do it?

The Bad:
I think its going to be stuck and I dont want to break it during removal
(its 130k and im doubtful if it was ever replaced)

Hey, I'll take a stab at it, B1S1 or bank 1 sensor 1 is before the cat, the first on in the exhaust.   The sensor you're looking at on Ebay is the universal kind, you'll have to wire it into your plug. As far as it bein stuck, they usually come out without too much trouble.  Just get a socket or box end wrench on it and pull like hell. The threads are sealed a little bit from the outside, so they usually will crack loose, but the threads on the inside are sometimes crudded up and can screw up the threads up comin out, so go slow.  If it won't crack loose you can use heat, but that will sometimes screw up the threads too.

Hope this helps!  Matt

I had major problems breaking the O2 sensor loose on a sidekick once.  Tried everything from an impact wrench to liquid wrench to heating it with a torch and nothing "standard" worked.  What I eventually decided to do was to create a temp difference between the O2 sensor and the manifold.  I put my O2 sensor socket in the freezer overnight, then the next day before taking the socket out of the freezer I drove the car and got the exhaust manifold good and hot.  Took the socket out of the freezer set it on the O2 sensor for a few seconds and then put the breaker bar on the socket and it popped loose on the second or third pull.  Guess it took it that long for the cold to penetrate down to the threads.

so thats the one on the header right?

im wary about breaking that sucker

Alldata says it's in the exhaust pipe below the manifold. What year?  I looked it up for a '96 16V.

If I'm not mistaken sensor #1 is on the manifold itself - sensor #1 is pre-cat (before the catalytic converter), sensor #2 is post-cat (after) - what I have not yet been able to determine is which is bank #1.

what I have not yet been able to determine is which is bank #1.

There's only 1 bank on an inline 4.  V-type engines have a bank 1 and 2.

Ummm - I don't see anywhere he says he's got an I4 - and if you're going by the pictures, Suzuki did put the H20A in that body style in the mid '90s

I broke mine trying to get it off, even after buying an o2 sensor socket.  The socket slipped and broke the sensor in half.  After a few whacks with a mallet, it broke loose.

for those that were wondering about which side bank one an bank two is on   whichever side cylinder number 1 is on  is bank 1  cylinder number 2 is bank two    obviously  this is only on v motors

the government is  the cause of the heated o2 sensors  on a one wire o2 sensors it had to reach 600 degrees before it would start swinging high an low for the ecm to reconize it government that was to long  to many nox an hydrocarbons on a cold start up so all the heater does is make it heat up quicker so the ecm wouldnt be guessing how much fuel was needed to run a cold engine   it goes on an on lol

can anyone clean this up?     (Im not able to understand)

= O2 sensor heater circuit pre heats the sensor on cold starts, so it can give the ecm accurate readings.

*scratches head*

and this answers my first post how?

It doesn't answer the question, but did I clarify?

can anyone clean this up?   Huh  (Im not able to understand)
