Engine light coming on with the code of p0420,0132,0152 if someone could chime in and let me know what i need to replace. hopefully whatever it is it's not doing any long term damage.it's a 05

sounds like you have a cat/oxygen sensors needing to be replaced

 

p0132 02 sensor ciruit high voltage (bank 1 sensor 1)

p0152 02 sensor ciruit high voltage (bank2 sensor 1)

p0420 catalyst system efficiency below threshold (bank1)

So i guess i have to replace bank 1 and bank 2 and i have no idea p0420 means. i guess i should go to the dealer and tell them bank 1 and bank 2 02 sensor?

 

is truck running bad? with both primary o2 sensors bad the truck should run like crap. Are you running aftermarket headers? may want to try resetting codes and see if they come back to confirm..

 

No, truck runs fine, wouldn't even know if the engine light wasn't on. no aftermarket headers either.i reset the codes but comes and go's but now it stays on.just not sure if i'm doing harm until i can have it fixed.

 

the front 02's control the heart of the air/fuel mixture/timing/spark and what not so normally if they go bad, the vehicle runs like crap, mileage suffers...

 

I have to agree, it looks like both front O2s to me also but did this come up out of the blue or did you have CELs for some time and just scanned and seen both being bad?
