Oxygen sensors are identified by bank and sensor position. Sensor 1 is always pre catalytic converter, sensor two is always post catalytic converter. If an engine is a 4 or 6 cylinder engine the whole engine is considered bank 1, if an engine is a V6, V8, V10....., the engine bank containing cylinder number 1 (first cylinder in the firing order) is considered Bank 1, the other bank is considered Bank 2. Interpretation Oxygen sensor designation B2S1 refers to Bank 2 Sensor 1, it will be the sensor on the engine side of the catalytic converter in bank two. Check this link to determine the cylinder that contains cylinder number 1. http://www.wellsve.com/custom_searches/ds_firing.php Wells Search Parts Catalog

Diagram of the location of a down stream o2 sensor on a 2005 chevy malibu.


Hi,
Downstream sensor is screwed into exhaust pipe after the catalytic converter on most models. Depending on your exhaust configuration, your code will say bank 1 or bank 2 or no bank designation. Some have converters coming off each cylinder bank (exhaust manifold off cylinder head) if only 1 converter in system (no bank) there will only be the one O2 sensor downstream.

How do I change o2 sensor on 2005 cobalt


Hi, place the Cobalt in "Park" on a level surface. Allow the Chevy to sit for 10 minutes. This will allow components to cool enough to touch but still be warm, which is ideal for replacing the oxygen sensor. Open the hood of the Cobalt and identify the oxygen sensor. Look for a white, rubber, plug-type sensor on the passenger side of the exhaust manifold; this is the oxygen sensor. Use a socket wrench paired with an oxygen sensor socket to loosen the sensor. Turn the wrench counter-clockwise until the oxygen sensor is loose. Remove the sensor from the manifold by pulling it off. The sensor will come off without much force. Insert the replacement oxygen sensor onto the manifold. Secure the sensor by pushing it into place until the sensor clicks. Close the hood of the Cobalt.
Take care

Where is a power steering pump located on a 4 cylinder chevy cobalt ls


Your Cobalt is not equiooed with a Power Steering Pump. It has electric power steering. See the description below.

Power Steering - System Description and Operation
The electric power steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the body control module (BCM), power steering control module (PSCM), torque sensor, discrete battery voltage supply circuit, EPS motor, serial data bus, and the instrument panel cluster (IPC) message center to perform the system functions. The PSCM, torque sensor, not the EPS motor are serviced separately from each other or from the steering column. Any EPS components diagnosed to be malfunctioning requires replacement of the steering column assembly, also known as the EPS assembly.

Why does reduce engine power light comes on chevy


That is a hard problem to pin point without knowing what codes the computer has stored. It can be any number or sensors or engine problems.

You can go to most auto parts stores and they will pull the codes for you for free.
