where is the bank1 o2 sensor at and how do i change it please i need your help
it is the one before the cat converter
Bank one are before the Cat and bank 2 are after the Cat.
Bank one sensor one is above the converter.
Bank 1 is the oxygen sensor either screwed into ,or above the catalytic converter. Bank 2 is below the catalytic converter.
It would be the sensor after the catalytic converter.
That would be the sensor after the catalytic converter.
Your in luck...that should be the oxygen sensor in the exhaust manifold at the front of the engine compartment. Bank 2 is the bank of cylinders that does NOT contain the #1 cylinder. That bank is bank 1. Sensor 1 is the oxygen sensor upstream of the catalytic converter, and sensor 2 is the one after the cat.
Passenger side exhaust
it is the upper stream o2 sensor before the convertor
behind the catalytic converter
Bank 1 sensor 2 is the sensor after the catalytic converterBank 1 sensor 2 is the sensor after the catalytic converter
its is located downstream on the backside exhaust manifold
There are 2 oxygen sensors, one i on exhaust manifold tubing , can be seen from drivers side of engine and second one is behind catalytic converter .
The oxygen sensor bank 1 is located in the exhaust manifold. The oxygen sensor bank 2 on the 1996 BMW 328is is located in the head pipe.
Bank one sensor two refers to the oxygen sensor. The bank one sensor two oxygen sensor is on the front side of the engine, after the catalytic converter.
A code, PO170, fuel trim malfunction Bank 1 on a 2001 Hyundai Santa Fe means that an oxygen sensor is bad. This oxygen sensor is located on the driver's side of the transmission.
That is the oxygen sensor screwed into the downstream side of the catalytic converter.That is the oxygen sensor screwed into the downstream side of the catalytic converter.
Bank 2 is the drivers side of the engine in your Ford Explorer Sensor 2 is after the catalytic converter ( downstream )
It is the one on the passenger side behind the catalytic converter
A 2001 Caravan with the 3.3L does not have a bank 2. Bank 1 sensor 1 is the one screwed into the rear exhaust manifold. Bank 1 sensor 2 is the one screwed into the side of the catalytic converter.A 2001 Caravan with the 3.3L does not have a bank 2. Bank 1 sensor 1 is the one screwed into the rear exhaust manifold. Bank 1 sensor 2 is the one screwed into the side of the catalytic converter.
Bank 1 is the side of the engine near the firewall. Bank 2 near the radiator. Sensor 1 is before the catalyse converter sensor 2 after the catalyse converter. In your case it is the O2 sensor that behind the firewall and after the CC.
Bank 1 is the passenger side of the engine ( V6 and V8 ) in a 2001 Ford Explorer Sensor 1 would be close to the engine before the exhaust enters the catalytic converter
it should be the bank facing the front of the car in the manifold. you should be able to find it right in front when open the hood
A B1S1 O2 sensor would be threaded into the exhaust system between the catalytic converter and the engine.
