How to Change an Oxygen Sensor

#1 is the up-stream sensor (The O2 sensor located before the Catalytic Convertor). #2 is the down-stream O2 sensor. This sensor is located after the Catalytic Convertor. I hope this helps, let me know if you have other questions concerning this issue. Good luck.

The DTC (Data Trouble Code) P0135 is for the O2 sensor Heater Circuit Bank 1 Sensor 1. Bank 1 will always be the cylinder bank with the number one cylinder and spark plug, and the number one O2 sensor will be located before the catalytic converter and usually at the rear of the exhaust manifold or just after it. According to the firing order diagram bank one is the cylinder bank that is closest to the fire-wall and there should be an O2 sensor located there around the rear of the exhaust manifold or just after it. If the engine is a 4 cylinder then it will be the O2 sensor before or up-stream of the catalytic converter. Check for any damaged wiring or loose wire connector at the O2 sensor and if they are alright then replace the O2 sensor and then re-set the check engine light. (The auto part store should re-set the check engine light for you if you purchase the O2 sensor from them, and be certain that it is the correct and assembled O2 sensor for your vehicle and not a put together universal O2 sensor)

The 3.0 is an ODB2 car so it has 2 o2 sensors. One before the CAT and one after the CAT. Check your headers for the primary heated o2 sensor location, and check on top of the cat for the secondary o2 sensor.

On almost every car, there is an O2 sensor located in the front, on the exhaust pipe, or manifold, and there is an O2 sensor located after the Catalytic converter. The front O2 sensor is the most important because it monitors the air/fuel ratio. The rear O2 sensor checks your Cat converter for proper operation and filtering.
