Oxygen sensor location

If you know what side Number 1 is then that is bank 1 sensor 2 is behind converter. Here is a guide to help walk you through the steps of changing it with diagrams below to show you the location.

Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Incorrect air/fuel ratio, contaminates in fuel (water for example).

Any coolant will destroy O2 sensors.

And they do wear out.

Some newer cars use wideband O2 sensors, these give feedback to PCM much more quickly that standard sensors, they are, however, more exprensive.

Realize that just because you have a sensor error, does not mean the sensor is the cause, a contaminated MAF sensor, incorrect fuel pressure, cylinder misfires can also trigger O2 errors.

Hello,

Thank you for the donation it is much appreciated.

The code def is.

P0153 Oxygen Sensor Circuit Slow Response (Bank 2 Sensor 1)

Here is how the Banks and Sensors go.

Bank 1 is on the Passenger Side (on Transverse Engines it the side against the firewall)

Bank 2 is the Drivers Side (on Transverse Engines it's at the front of vehicle)

Bank 1 Sensor 1 = Is in the Exhaust Manifold.

Bank 1 Sensor 2 = The next one back in same pipe

Bank 2 Sensor 1 = Is in the Exhaust Manifold

Bank 2 Sensor 2 = The Next one back in same pipe
