How do i fix a code p0134 for my 1999 infintiy i30


code p 0134 refers to heated oxygen sensor(HO2S) 1 bank 1--no activity detected ===causes wiring open circuit ---heating inoperative ---HO2S Sensor
also refers to oxygen sensor (O2S) --no activity detected ===causes --- wiring---O2S
the HO2S is in the exhaust manifold before the cat converter
the O2S is after the cat converter
check the wires and connections , then replace either or both sensors

Is all the O2 sensors the same on a 2002 Mitsubishi Diamante ?


all O2 sensors are the same and all HO2S sensors are the same
But a HO2S sensor is different to an O2 sensor
HO2S sensors are in the exhaust manifold before the cat converter and O2 sensors are in the exhaust pipe after the cat converter
so what sensor exactly are you refering to

P1884 code 2005suzuki forenza P0420 P0134 P0138


code p 420 refers to cat converter system , bank 1--efficiency below threshold ===causes ---cat converter faulty---wiring --heated oxygen sensor (HO2S), 2 faulty
code p 0134 refers to HO2S 1 bank 1-no activity detected ===causes --wiring open circuit -- heating inoperative --- HO2S
also refers to oxygen sensor ( O2S) 1 bank 1--no activity detected == causes wiring ---O2S
code p 0138 refers to HO2S 2 bank 1--high voltage === causes ---wiring short to positive ---HO2S--- ECM
also refers to O2S 2 bank 1 high voltage === wiring short to positive O2S -- ECM
I do not have a listing for code p 1338 but I suspect that it will refer to the other codes in some way
first fix is to check the cat converter is operational ( not cracked and blocking the exhaust system)
next replace the HO2S sensor ( one before the cat converter ) and then the O2 sensor (the one after the cat converter)
all the codes will relate to problems in that area

Po136-o137 says change 02 sensor on bank 1 sensor2 I did but engine light is still on 2004 chevy tahoe


code p 0136 refers to heated oxygen sensor (HO2S) 2 bank 1 ---circuit malfunction===causes ---heating inoperative ---wiring---HO2S--- ECM
also refers to oxygen sensor (O2S0 2 bank 1---circuit malfunction===causes --- wiring---O2S ---ecm
it also refers to heated oxygen sensor (HO2S) 2 bank 1 ---no signal===causes ---wiring --- HO2S---
code p 0137 refers to HO2S 2 bank 1 ---low voltage -===causes --exhaust leak---wiring short to ground ---HO2S--- ECM
it also refers to O2S 2 bank 1---low voltage ===causes exhaust leak---wiring short to ground ---O2S ---ECM
to set you up here-- there are 4 oxygen sensors in the system
2 are heated oxygen sensors (HO2S) on in each exhaust manifold or exhaust pipe before the cat converter and
2 oxygen sensors (O2S) -- one in each exhaust pipe after the cat converters
heated oxygen sensors have 4 wires and O2S sensors normally only 2 wires
it is more that possible that you changed the wrong sensors and in the process damaged the delicate wires with the incorrect spanner being used

Hi Michael, After fixing errors you need to reset your computer by disconnecting the battery for a minute or two, Also you'll need your radio code to reset your radio, I hope this helped...........CHEERS..

I aready changed the ho2 sensor 1.why also start the engine after second check engine lights also come.i scandal the code also same.HO2S(S1)failure.how to fix for honda accord 2.0CC model SDA


there is a difference in the operation of a HO2S and a O2 sensor and replacing the wrong will not fix the problem
one(HO2S) reads the gas mixture before the cat converter and the other (O2)after the cat converter

If I'm receiving the code stating Heater Control Sensor 2 Bank 1, but I've verified the wires are correct on the 02sensor. What is another possible problem?


o2 sensor id fai;led and needs replacing
the heater control is for the HO2S sensor which is different to the O2 sensor
the heater control sensor (HO2S) is before the cat converter and the O2 sensor is after the cat converter
because you have bank 1 then there are 2 HO2S sensors and 2 O2 sensors

How many o2 sensore are on the 99 bravado? I replaced the o2 sensor before the cat converter, now code says bank one( before cat.) needs replacing. are there 4?


the sensor before the cat is NOT an O2 sensor but a HO2S sensor ( two different sensors with different operations). If this is a V6 engine there are 4 sensors -- 2 --HO2S sensors before the cats --one for each bank cat and 2 O2 sensors after the cats.
The fault code would have spelt out the correct sensor for replacing

How many O2 censors in a 98 Maxima


In cars with EFI control there is a heated oxygen sensor(HO2S) before the cat converter and a ordinary oxygen sensor (O2S) after the cat convertor. so that means 1 of each on a 4 cylinder engine and 2 of each on a "V" engine . They are not interchangeable so a O2 sensor will not replace a HO2S sensor

Diagnostic-codepo159


code p0159 refers to heated oxygen sensor(HO2S) 2 bank 2 --slow response Same for the oxygen sensor (O2S) ==causes --heating inoperative -wiring--HO2S sensor for the HO2S sensor and for the O2S sensor --wiring and sensor fault.

the HO2s sensors are before the cat convertor and the O2 sensors are after the cat converter.
