Where is the O2 sensor in bank 2 located in your 1996 Isuzu trooper?
Bank 1 is the side that cylinder 1 is on, sensor 1 is downstream and sensor 2 is upstream
Where is the bank 1 O2 sensor on a 2003 Jeep Liberty 3.7 engine?
Bank one is the driver side on a 3.7L. There will be an upstream ( sensor 1 ) and a downstream ( sensor 2 ).
Where is the Bank 1 O2 sensor on 2003 Hyundai Accent?
All O2 sensors are threaded into the exhaust system. Bank 1 is the bank of cylinders that contains the number 1 cylinder. Sensor 1 is upstream (before the catalytic converter) and sensor 2 is downstream (after the catalytic converter). Your Accent has a 1.7 4 cylinder engine and has only one bank of cylinders. But it has 2 O2 sensors, one before (upstream) the cat and one after (downstream) the cat. The upstream sensor may also be called the Air/Fuel sensor.
Where is o2 sensor bank 2 on a 97 gmc sierra 1500?
Bank 1 = Cylinder 1/Drivers Side Bank 1 Sensor 1 = Upstream (before cat) Drivers Side Bank 1 Sensor 2 = Downstream (after cat) Drivers Side Bank 2 Sensor 1 = Upstream (before cat) Pass Side Bank 2 Sensor 2 = Downstream (after cat) Pass Side
What is bank 1 sensor 2 code P0140?
No activity from B1 S2 O2 sensor circuit. Check O2 harness and connecter for damage. If harness and connecter look good replace faulty B1 S2 O2 sensor. This is the sensor after the B1 catalytic converter (AKA downstream O2 sensor). B1 (Bank 1) is the bank of cylinders that contains the number one cylinder.
Are the 2002 downstream sensors O2 sensors labeled left and right from the hood or the drivers seat?
On a Ford Expedition : Bank 1 , Sensor 2 ( downstream ) is the sensor for the passenger side of the engine Bank 2 , Sensor 2 ( downstream ) is the sensor for the drivers side of the engine So in short the answer is from the ( drivers seat )
2001 Ranger 4x4 4L Where is o2 sensor bank 1 sensor 2?
Bank 1 is the passenger side of your engine Sensor 2 is after the exhaust gas has passed through the catalytic converter (downstream)
What does code134 mean on Kia Sportage?
O2 circuit, bank 1 sensor 1, now in english you have an O2 sensor gone bad.You have 2 of them, an upstream and a downstream one. I would suspect the upstream one.
I have an 05 ford f150 4.6 liter V8 Where is sensor is O2 Sensor Bank 1 Sensor 2 located?
Bank 1 is the passenger side of the engine Sensor 2 is after the exhaust has passed through the catalytic converter ( downstream )
Where is bank 1 on the O2 sensor of a 98 Ford Ranger 4 cylinder engine?
"bank one" is misleading on a four cylinder engine, since there is only one bank to begin with. Bank 1, sensor 1 is the upstream O2 sensor screwed into the exaust system before the catalytic converter. Bank 1 sensor 2 is screwd into the exaust system downstream of the catalytic converter.
How many O2 sensors in a 98 Mazda Protege?
There are 2 sensors 1 upstream and 1 downstream to tell which one is bad use a scan tool if the code says bank 1 sensor 1 it's the upstream if it's bank 1 sensor 2 it's the downstream
Where is the bank 1 o2 sensor on a 2007 gt mustang?
Bank 1 is the passenger side of the engine in your Ford Mustang Sensor 1 is in the exhaust BEFORE the catalytic converter ( upstream ) Sensor 2 is in the exhaust AFTER the catalytic converter ( downstream )
