The oxygen sensor is usually located on the exhaust system. You should find it just after the exhaust manifold and just ahead of the ctalytic converter...Don the Juan.

the O2 Sensor Should be on top of your exhaust manifold

The upstream O2 sensor is mounted in the ehxaust manifold The downstream O2 sensor is mounted in the exhaust pipe after the catalytic converter

Downstream O2 sensor is an O2 sensor after the catalytic converter. Upstream O2 sensor is an O2 sensor before the catalytic converter.

It's the sparkplug looking thing sticking out of the exaust somewhere around the catalic converter

the o2 sensor is in the exaust manifold or down pipe it looks like a sparkplug with wires

P0133 means "Oxygen Sensor Circuit Slow Response (Bank 1, Sensor 1)." Your car may be running rich and using excess fuel. Check the O2 sensors, especially the first O2 sensor before the cat, and check to be sure you don't have any exhaust leaks. I had this code appear once on my 2002 VW Jetta 1.8t, and replacing the front O2 sensor fixed the problem.

Bank 2 sensor 1 is the O2 sensor in the exhaust manifold closest to the firewall.Cut and paste the link below for a detailed fix with pics of the O2 sensor repair."http://polifrogblog.blogspot.com/2009/11/sienna-o2-sensor-change.html"

It screwed in to the exhaust manifold. To change it you unplug the sensor and unscrew it with an O2 sensor socket.

An auto xray scanner can determine if a O2 sensor is bad.

User Avatar

check on the exhaust manifold and the catalytic converter. there are possibly 2 O2 sensors. unplug them and unscrew them with a wrench or buy a socket for an O2 sensor.

User Avatar

Bank 1 sensor 3 would be the O2 sensor after the catalytic converter.

User Avatar

You need to purchase the tool for removing the O2 sensor. It's a socket that has a slit down the side for the O2 sensor cable. This will cost you about 20-30$. The 02 sensor will un-screw with a socket wrench. Best done when car is cold. Otherwise you will burn your hands. Good luck.

the bank 2 o2 sensor is the second o2 sensor back on the exhaust. -------------------------------------------------------------------------------------- Bank 2 is the drivers side of the engine Sensor 1 would be before the exhaust gas reaches the catalytic converter Sensor 2 is after the exhaust gas has passed through the catalytic converter

User Avatar

These codes are for the O2 Sensor - One is for the heater core inside the O2 Sensor, the other is the sensor. It's gone bad! - No Activity, is what it will read. It's the (Bank 1 Sensor 2) Not sure where it's located, ibelieve it's right in front of the Cat. good luck.

Not sure which sensor u are talking about but 1999 Aurora's have 4 O2 sensors, one on each header and one before and 1 after the catalytic converter.

The epc light in your VW Jetta could be on for many reasons. Your VW Jetta may need a new brake light or it could need an O2 sensor. The best thing to do is take it to a mechanic so they can properly diagnose the problem.

9 time out of 10, the heater circuit internal to the sensor has failed. Replace the sensor.
