On a 1999 Porsche 911, the upstream oxygen sensor is located in the exhaust system, specifically before the catalytic converter. It is typically mounted directly in the exhaust manifold or in the exhaust pipe just downstream of the manifold. This sensor plays a crucial role in monitoring the air-fuel mixture for the engine's performance and emissions control.
The upstream heated oxygen sensor is located ahead of the catalytic converter The downstream heated oxygen sensor is located behind the converter
The upstream O2 sensor is mounted in the ehxaust manifold The downstream O2 sensor is mounted in the exhaust pipe after the catalytic converter
The upstream oxygen sensor is located in the exhaust pipe between the exhaust manifold and the catalytic converter The downstream oxygen sensor is located at the catalytic converter outlet
There are 2 sensors The upstream O2 sensor is mounted in the ehxaust manifold The downstream O2 sensor is mounted in the exhaust pipe after the catalytic converter
I'm not a mechanic / technician but I assume that would be : Bank 2 , sensor 1 Bank 2 is the drivers side of the engine in a 1999 Ford Explorer Sensor 1 would be the oxygen sensor somewhere in the exhaust before the exhaust enters the catalytic converter ( upstream sensor )
Code P0135 indicates a malfunction in the oxygen sensor circuit for the upstream (bank 1) sensor on a 1999 Toyota Camry Solara. To repair this issue, start by inspecting the wiring and connectors for any damage or corrosion. If the wiring appears intact, you may need to replace the upstream oxygen sensor itself. After replacement, clear the error code and test drive the vehicle to ensure the issue is resolved.
On a 1999 Toyota Corolla, the oxygen sensor is typically located in the exhaust system. There are usually two sensors: one upstream (pre-catalytic converter) and one downstream (post-catalytic converter). The upstream sensor is found on the exhaust manifold or near the front of the catalytic converter, while the downstream sensor is located further along the exhaust pipe after the catalytic converter. You may need to lift the vehicle or access it from underneath for better visibility.
In the 1999 Mitsubishi 3000GT, Bank 1 Sensor 1 oxygen sensor is located on the driver's side of the engine, upstream of the catalytic converter. It's positioned in the exhaust manifold or just after it, before the exhaust gases enter the catalytic converter. This sensor monitors the oxygen levels in the exhaust gases to help regulate the air-fuel mixture for optimal engine performance.
upstream sensor will be located before the cat downstream sensor will be located on the cat itself
How many oxygen sensor on your 1999 3.5 rl?
Four
1)Upstream sensor is located in the "y" pipe ahead of the catalytic converter. 2)Downstream sensor is located between the catalytic converter and the expansion chamber.
