Hey everyone,
Well are D2 decided to throw codes for all 4 O2 sensors and it seems strange they would all fail at once. Has anybody come across this before and these sensors were just put this morning to replace what we thought were bad O2's.
All o2's failed at once !

Running leaded gas would cause that but I don't think you could find any if you tried, perhaps some other additive you might have added to the gas?

Re: All o2's failed at once !
The common denominator seems to be the fuel / exhaust mixture ...
Maybe the fuels not burning well? How are your spark plugs? Possibly some other emission control component that is a joint factor.
Hopefully its not water or oil in the exhaust from Head gasket or cracked block :shock:
Do the codes take a while to pop up right at start up or take a few kms to show up? What are the codes you are seeing?

Hey Andy,
The problem has been solved.
It turns out that the power supply wire to the O2 sensors that controls the heater part of the O2 shorted. Its fixed now and that truck is performing perfect.
Thanks for the help and reply.
