What else can I help you with?
How do you tell if an oxygen sensor is upstream or downstream on a 2002 Chevy silverado 1500?
Upstream would be before the catalytic converter. Downstream would be after the catalytic converter.
Is the upstream oxygen sensor the same as the downstream oxygen sensor?
no. the upstream sensor is the one before the catalytic converter and the downstream is the one after
Do you need upstream or downstream oxygen sensor?
Depends on what the problem is or what code was set.
Where is the oxygen sensor located on Plymouths?
There is an upstream and downstream o2 sensor. The upstream is loctaed in the exhaust manifold before the catalytic converter. The downstream is located behind the catlytic converter.
Where is the upstream and downstream oxygen sensors located on a 99 dodge stratus?
before and after catalytic converter.
How many o2 sensors are on a 2004 Hyundai tiburon?
The 2004 Hyundai Tiburon is equipped with two oxygen sensors: one upstream (pre-catalytic converter) and one downstream (post-catalytic converter). The upstream sensor monitors the air-fuel mixture before it enters the catalytic converter, while the downstream sensor checks the efficiency of the catalytic converter.
How many oxygen sensors are on a 1998 Ford Windstar Van?
There are four. Two on the upstream (before the catalytic) and two after catalytic converter (downstream).
How many 0 2 sensors are in a 1997 Ford Expedition Eddie baur?
I believe there are ( 4 ) Bank 1 is the passenger side of the engine , sensor 1 is before the catalytic converter ( upstream ) and sensor 2 is after the catalytic converter ( downstream ) Bank 2 is the driver side of the engine , sensor 1 is before the catalytic converter ( upstream ) and sensor 2 is after the catalytic converter ( downstream ) The 2 sensors before the catalytic converter are used for air / fuel ratio for the engine The 2 sensors after the catalytic converter are called catalyst monitors
Where is the 02 sensor on a 02 Kia Sportage?
On a 2002 Kia Sportage, the oxygen (O2) sensor is typically located in the exhaust system. There are usually two sensors: one is positioned before the catalytic converter (upstream) and the other is after the catalytic converter (downstream). You can find the upstream O2 sensor on the exhaust manifold or just before the exhaust pipe connects to the catalytic converter. The downstream sensor is located on the exhaust pipe after the catalytic converter.
Where are the o2 sensors on a 2006 chrysler pacifica?
On a 2006 Chrysler Pacifica, the oxygen sensors are located in two main areas: upstream (pre-catalytic converter) and downstream (post-catalytic converter). The upstream sensor is typically found on the exhaust manifold or just before the catalytic converter, while the downstream sensor is located after the catalytic converter. There are usually two upstream and two downstream sensors, one for each bank of the engine. You may need to access the undercarriage or remove some components for easier access.
Where is O2 sensor on a 2004 Ford Taurus?
The O2 sensor on a 2004 Ford Taurus 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 located on the exhaust manifold or just before the catalytic converter, while the downstream sensor is found after the catalytic converter. You may need to lift the vehicle for better access, especially to the downstream sensor.
Is the bank 2 sensor 1 on an 2000 Infiniti I30 upstream or downstream?
Sensor 1 would be UPSTREAM before the exhaust enters the catalytic converter
