How far apart should O2 sensors be?
Ideally, the O2 sensor should be placed at least 24 inches downstream from the cylinder head exhaust ports. This ensures that the O2 sensor takes its measurements after the exhaust gas from each primary merges into a common collector.
Where are Bank 1 and 2 O2 sensors located?
Bank 1 Sensor 2 is the second sensor on the engine’s exhaust pipe, usually behind the catalytic converter. Located on Bank 1 means it is located at the engine side with cylinders 1, 3, 5, 7, etc. Bank 2 Sensor 1 is the first sensor closest to the engine.
Where are Bank 1 and Bank 2 located?
Bank 2 Sensor 1 is the first sensor closest to the engine. Located on Bank 2 means it is located at the engine side with cylinders 2, 4, 6, 8, etc. Bank 2 Sensor 2 is the second sensor on the engine’s exhaust pipe, usually behind the catalytic converter.
Where is Bank 2 on a car engine?
Bank 2 is the side with cylinders 2, 4, 6, 8. The easiest way to discover the right cylinder bank is to check your car’s repair manual. You can also try to find any stamps on the cylinder block or head for any cylinder numbers. The front of the engine is the part where the crankshaft pulley is.
Where is the O2 sensor on a catalytic converter?
Bank 1 Sensor 1 = O2 sensor located before the catalytic converter, on the side with Cylinder #1. Bank 1 Sensor 2 = O2 sensor located after catalytic converter, on the side with Cylinder #1. Bank 2 Sensor 1 = O2 sensor located before the catalytic converter, on the side with Cylinder #2.
Where is Bank 2 sensor 1 located?
Bank 1 Sensor 2 (downstream) is located just past the drivers side catalytic converter. Bank 2 Sensor 1 (upstream) is located just below the exhaust manifold, in the pipe, at the front of the van – access is from the top.
Where is the bank 1 O2 sensor located?
Bank one is the engine cylinder bank near the engine firewall (see diagram). The bank one sensor one is the Oxygen sensor (O2) located in the exhaust pipe just of the engine cylinder bank at rear and before the Catalytic Converters .
Where is the oxygen sensor Bank 1?
Bank 1 sensor 1 means the first oxygen sensor closest to the motor. The location is probably in the exhaust manifold, if not then follow the pipe from there and it’s the first one you find.
