BH5 front O2 sensor


lunacy

Recommended Posts

Hey guys.

Got a CEL today and after plugging in the OBD2 reader seems my front O2 sensor is stuffed.

As mine is a rev d I'm a bit lost as to which sensor I need, as some say this is a wideband one and others that it's not? Anyone have any idea? Oh and a gd place to buy these from?

Thank

So randomly as I went to check the part number on the sensor, I find that it is almost unscrewed from the exhaust. Was only held in with a couple of threads! So tightened it up, reset the ecu and no codes yet! Fingers crossed...

Right so I've replaced the sensor after the OBDII code 1130 was showing and stil havnt got rid of the CEL. I've reset the ecu but light comes on again after 30 sec of driving. Car feels very sluggish when cold now too. Grrr any ideas?

So went to put old sensor back in as car actually seems worse with new sensor in. Just for **** and giggles I left the sensor unplugged and let the car warm up to normal temp. Did nothing unusual at all. I blipped the throttle a couple of times and it revved ok. Would have thought it would have run terribly without the o2 sensor

Old thread but mine does the same, the heater core in the rear sensor or something doesn't work in my 02 sensor, so when the engine is up to the right temp, I turn car off and on again (I work in IT, never fails) and the CEL doesn't come back because the sensor is already at the right temperature.

Our RevD's have 2 sensors. Or something like that.

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
