O2 Sensor Circuit High Voltage Bank 1 Sensor 2 Location

B2 is located on the opposite bank.

O2 sensor circuit high voltage bank 1 sensor 2 location. How to repair p0138 code o2 sensor circuit high voltage bank 1 sensor 2. Today s engines come with oxygen sensors with heating elements ho2s. Diagnostic trouble code dtc p0138 stands for o2 sensor circuit high voltage bank 1 sensor 2. S1 means the sensor is located before the catalytic converter.

The o2 sensor could be functioning improperly or there could be a lack of continuity in the wiring to the ecu or it is possible that power is not supplying sufficient enough voltage to the sensor. P0138 description the heated oxygen sensor 2 ho2s rear o2 sensor after three way catalyst manifold monitors the oxygen level in the exhaust gas on each bank for optimum catalyst operation the air fuel mixture air fuel ratio must be maintained near the ideal stoichiometric ratio. The o2 oxygen sensor circuit high voltage bank 1 sensor 2 is normally located in the catalytic converter before the muffler in the. There are two types of engines inline engines and transverse engines engines that are mounted in other directions.

Bank 1 sensor 2 is located at the back of bank 1. If you know which cylinder is 1 it wouldn t matter anymore whether your engine is transverse or inline as bank 1 will always be on the cylinder marked 1 3 5 7 9 11 and bank 2 will always be on the side of the cylinder marked 2 4 6 8 10 12. The heated oxygen sensor 2 ho2s rear o2 sensor after three way catalyst manifold monitors the oxygen level in the exhaust gas on each bank. Bank 1 vs bank 2.
