P0031 -02 sensor heater heater circuit low bank1 sensor 2
P0030 -02 heater control circuit malfunction
P0132 Oxygen sensor circuit high voltage (bank 1 sensor 1)
P0132 is for bank 1 sensor 1 which is the engine management sensor when it a high voltage recheck the harness for proper connection and also the wiring harness a definition of circuit high mean it is not connected, Recheck the connection and make sure the 02 is properly torque or tighten a loose installation can also set these codes.

1/1 is upstream sensor on the number 1 cylinder side, 1/2 is the downstream of the number 1 cylinder side, 2/1 is the upstream of the number 2 cylinder side, 2/2 is the downstream of the number 2 cylinder side. Hope this helps.

SOURCE: 420 code catalyst system efficiency below

You could have an enefficient converter. Question is what caused it to go bad? I have attended seminars on code 420, Possible causes are lack of spark or clogged fuel injectors. there have been times where the spark plug wire lays on the engine and over time it wears a weak spot in the side of the wire, its not enough to throw a miss fire code but it keeps the full amount of spark from getting to the plug and not burning the all the fuel in the cyl. A leaky injector would also cause to much fuel to be deliverd into the cyl and not get burned.

Hope this helps.

2003 honda civic o2 how to replace And how do i fin out which once is it


Hi Jesus, Im AL the owner of Big As Auto Repair.

If you have a 4 cylinder engine then you will only have two 02 sensors 1/1 is upstream and 1/2 is downstream. Upstream is the one closet to the engine and downstream is the one farther away from the engine.

If you have a six OR eight cylinder engine you will have four 02 Sensors. 1/1 means Bank One Sensor One. 1/1 and Bank one means right bank and right bank means the side with the number 1 spark plug. SO, 1/1 means, "Right Bank" Upstream 02 sensor. 1/2 means, "Right Bank" Downstream 02 sensor.

2/1 means, "Left Bank" Upstream 02 sensor and 2/2 means, "Left Bank" Downstream 02 sensor. Hope this helps and please visit my auto-repair-website at: http://www.bigasautorepair.com/

Can an O2 oxygen sensor effect another sensor and give a false reading?


Check which side of your engine has cylinder #1. That side is bank 1. Bank 2 is the side opposite of bank 1. So bank 2 is not always passenger side. And since you seem to have extra O2 sensors, I would replace the other upstream and see what happens. Also the mass air sensor can give a trouble code issue to the upstream 02 sensors. Good luck. I've struggled thru this myself.

Check engine code O2 sensor p0132


New PCM plugs and wires? hun?
new harness ,why? in a fire or wreck? running off road?
or did you mean, new PCM, new spark wires, and all new 02s sensors' It wont be a bad PCM , sorry, 99% are good.
P0132
the PCM never lies. it measure this and does a test and if it fails there is a circuit fault.
the why to understand, DTCs (have a FSM factory serv. manual)
and read how the test works. or do the tests it tells you do to
to discover true cause)
i have this car v6 3.8L: and 6speed and the FSM, book.
verbatim.
O2 SENSOR 1/1 CIRCUIT HIGH
1/1 means bank 1 , front sensor (upsteam)
bank one means right bank, cylinder 1 side.
what does HIGH mean?

what is not clear is which side is failing, heater or CELL
this test is the CELL pin (oxy out)
pin 4.
the test (called a monitor) finds that pin 4 is stuck at 5v.
the o2 must be 0 to 1volt at all times.
if stuck at 5vdc then the ground is open to CELL pin 3 (wire cut)
or the 02 sensors is bad. (open)
do you know how to back probe? a skill that is must for all modern cars. use needles with your meter. (DMM) (leather needles work in a pinch sold at walfart for 1buck) needle probes are 10x better
key on and back probe pin 4, if at 5vdc or more(or near) it's wrong.
btw page 2891 shows what to do in the FSM. yah 7000 pages.
I think this pin floats to 5v if the wire is cut.

fail 2 is that pin 4 is shorted to voltage ,well , the heater runs off
of 12v and all cars (bad service) the 2 wires melt and short.

here ill list all 4 pins (key on)
1- 12v heater.
2- ground
3 - ecu quite ground to 02 (cell minus)
4- CELL + out (this is the oxy signal)

pin 4 must not be at 5v or 12v, but 0 to 1 volts.
at key on or running.


one more FSM quote
Measure the voltage in reference to ground, not the (K902) O2 Return Upstream circuit.

that means pin 3 to 4, is measured for best accuracy
but 5vdc or 12vdc is gross wrong .

if the o2 is new (is)
then this quote covers most fails on most cars
Look for any chafed, pierced, pinched, or partially broken wires.
Look for broken, bent, pushed out or corroded terminals. Verify that there is good pin to terminal contact
in the Oxygen Sensor and Powertrain Control Module connectors.

here is the wiring.
if you need more photos full size or more tests.
or have questions, ask, i'm a retired ET, (controls systems , PLCs +)

How many oxygen sensor on a 02 chevy blazer


Hi, there are 4 sensors on your truck--two upstream and 2 downstream. The upstream sensors are mounted in the exhaust manifolds and the downstream sensors are mounted just behind the catalytic converters. The upstream and downstream sensors are different. Bank 1 is on the driver's side and bank 2 is on the passenger's side. Please let me know if you have more questions, and thanks for using FixYa.

Whats the difference between up and downstream sensor on a chevy s10 1997, what exact sensors do i need for bank 1 and bank 2 sensor1


Well upstream from the Catalatic Converter means towards the engine and that would be the location for Sensor #1 on both sides of the engine. And Downstream would be away from the engine past the Catalatic Converter For Sensor #2 on both sides of the engine. Bank 1 or Bank 2 would indicate which side of the engine the trouble is on. ( Bank #1 is the side of the engine that contains #1 Cylinder. Please remember if you are going to change one 02 Sensor then you should change all of them and be sure to clear all codes after all repairs are finished. that will turn the check engine light off. Good Luck and have a good XMASS.
