Need more info, is this the 4 cylinder or 6 cylinder engine and which sensor on bank 1.
In the back end of the transmission.
That should be the sensor located after the catalytic converter.
Bank 1 sensor 3 would be the O2 sensor after the catalytic converter.
That would be the O2 sensor after the catalytic converter.
on the distributor @ 2 oclock
4.3L? Inside the distributor.
That should be the O2 sensor just before the catalytic converter.
Bank 1, on a 4.3 L engine would be on the drivers side.
A 4WD on a 2001 Chevy S10 Blazer does not work properly after changing its actuator and speed sensor probably due to shorted wires. Also check for loose wiring.Ê
Passenger side exhaust pipe directly after the exhaust manifold.
Assuming this is a V-6, bank 1 sensor 1 would be the first O2 sensor in the exhaust on the drivers side of the engine.
Bank 1 fuel too lean Probable causes: Vacuum leak at engine, bad intake gasket, exhaust leak before an o2 sensor, map sensor
