it is good, the trims work, but the CEL goes off 24/7. ill report back if it happens with denso one.

 

Also check for the following:
Wiring or connector to the sensor frayed / broken
Blown heater circuit fuse
Holes in the exhaust system as mentioned earlier
PCM failure (very rare but possible and would only be the last resort)

Is there any evidence that your o2 sensor was dropped? it could become damaged and throw that code also, even on a brand new o2 sensor.

My 03 was bogging like no ones buisness without the primary wow.

 

Is the new Denso sensor good?

 

It's possible it might have been...three years ago when the original post was made...lol.

 

Ya denso sensors good. running the same one from 2010 also still lol! I prefer Denso over bosch for this narrowband o2 replacement.
