Hello, how can I resolve an error code B0001 for a 2004 Isuzu Ascender with a 4.2L engine? Thank you!


There are no results for this error, scan and see if a different error pops up. You can go to any auto parts store to get it scanned as long as the check engine light is on. Advanced Auto etc, Auto zone. God Bless! Its free!

Were is O2 sensor in ascender 204 engine


ah crapp, its 2014 post , got sucked in....

same on all cars, you meant 2004 engine right, but no engine stated. ok 4.2L I-6, LL8 by GM. used on also.
Chevrolet TrailBlazer, GMC Envoy, and Oldsmobile Bravada

there are 2,
one before the cat, and one behind it. (most cars)
its the only thing on exh, header with wires...
that melt.
just knowing that the sensor measure, oxygen at the exhaust collector answers that))
Some engines, I-6 for calif laws, have split exhaust manifolds
and acts like V6, 2 senors front 1 rear of cat. for 3 total
i just look first for split headers... below is not, its regular kind
the 02 front is here.

here is the fed version
