I ran around 5000mile with rrm header and it damaged my o2 sensor OEM sensor cost around $300, man they are expensive
is anybody else's o2 sensor damaged because of aftermarket header???

 

I've ran turbo'd and NA on the same sensor with both the stock and RRM header. With over 50k miles like that the stocker is still going strong. Maybe it was damaged in removal/re-install or it may just have been a bunk sensor. Throw the stock header back on and have the dealer waranty the sensor... as long as they never find out about the RRM header your golden.

 

hmmm this is what the obd2 reads
"po132 bank 1 sensor, 1 of 2 o2 sensor, sensor circuit high volt"
oh yeah after i putted stock header back on it still pop up with same code..
so my sensor is bad right??
man i miss my header,,

 

by the way i am not blaming rrm header for my o2 damage... rrm header is great. i love the pull from it! hit us with more goodies!!!

 

probably fouled. dunno how it would generate high voltage otherwise. if you didn't put the header on right(inside nuts first then work your way to the outside ones) you could have caused a lean leak and the ecu could have just been dumping all kinds of fuel.

 

That's a good point... check for the exhaust leaks around the flange and pull out the O2 sensor. Give it a good cleaning with some break clean and a toothbrush. Get all the carbon off it you can. For 10-15 bucks mitsu has the header gasket. If you want just replace it new and torque from the center out. Lastly reset the ecu and let us know how it works out.

Doesn't sound like the sensors bad it sounds like there is a condition happening it doesn't like.

 

ditto boe
i have 49k miles and went throught RRM
turbo then a custom setup still good o2
sensor for me just cleaned it up...

 

for putting on header i did outside toward inside. i guess i did it backward. i will try it again. thank you

 

that probably is it... if your leaking prior to the sensor it will read super lean and give you the higher voltage readings.

 

i redone everything and still the same error, and i have a/f gauge!! it reads stoich, which mean i am not running on lean!!! i guess i have bad o2 sensor!!

 

a new o2 sensor cost me 30 bucks on ebay. OE too

 

Here is the cheapest one I found so far... http://pa.partsandaccessories.com/pa...=Oxygen+Sensor

Hope it will help out

 

I just noticed the previous one says mitsu landcrusier?... even though the previous option said lancer. oh well, heres another... http://www.bosch4less.com/index.cfm?...rs=2&xfuel=GAS
