i have this code sortted only
P0036 HO2S Heater Control Circuit (Bank 1 Sensor 2)


please help me to fix this and what should i do

thanks

 

Well with a 106k on the clock I'd go with you need a new oxygen sensor.

If you read the codes then you have the ability to clear them. Did u try clearing and see if it comes back ?

yes i have cleared the code
and they come back again
but does it make car go into limp mode

 

A new O2 sensor will fix this, clearing the code should be done after fixing this, clearing the code will not fix the faulty O2 sensor. ECU will not necessarily go into Limp Mode every time a code is thrown.

If you had Googled "P0036 HO2S Heater Control Circuit (Bank 1 Sensor 2)" you would have found your problem here which tells you what's wrong with your car.

 

hi thanks for your replay
what should i replace which is located on top or bottom

thanks

 

sorry
i mean after cat or before cat ?

 

Its after the cat about half way down the car.

 

Thanks

 

i have replaced o2 sensor and check engine go away
and im still in limp Mode (Safe Mode)

please help what should i do the car runing very slow
everything is new spark plug and coils and all filters Fuel Air And Oil Filters

 

Clear the code.

 

i have cleared the code and still the same

 

Replace the other o2 sensor then. See what happens. Is it the same code that keeps popping up?

 

nothing is shown no faults at all

 

So you are getting a CEL with no codes and it won't reset? Are you tuned?

 

Disconnect the battery for an hour then reconnect, that should reset the ECU. Which O2 sensor did you replace, Bank 1 Sensor 1 or Bank 1 Sensor 2?

replaced bank 2
and i have disconnect battery and still the same

 

no its factory without any tune

 

It must be the wiring, time to have a continuity test between where you connect the O2 sensor and the ECU.

 

just bumping this thread. having the same problem curious if you figured it out.

 

Hi guys did you fix the problem?

 

i never did figure it out, couldn’t afford to keep throwing parts at the car, ended up selling it but still stuck on it afterwards thinking what it could’ve been I landed on most likely my issue being the diverter valve. Hope that helps!
