Trouble code P2238 means: O2 sensor positive current control circuit low bank 1 sensor 1
Bank # 1 is the passenger side of the engine Bank # 1 , SENSOR # 1 , is close to the engine in the exhaust Bank # 1 , SENSOR # 2 , is in the exhaust after the catalytic converter ( downstream )
O2 Sensor malfunction, Bank 1, Sensor 1
On a Lincoln Navigator : Bank 2 is the drivers side of the engine * sensor 1 would be close to the engine BEFORE the exhaust enters the catalytic converter
Bank one is simply the side of the engine with the number one cylinder. In this case it is the right side of the engine up against the fire wall. If you go under the vehicle you will see the exhaust coming down from behind the engine. There will be one sensor in front of the cat and one after. The sensor before is called bank 1 sensor 1, the sensor after the cat which you are looking for is called bank 1 sensor 2.
Bank # 1 is the passenger side of the engine in a Ford Expedition Sensor # 1 would be before the catalytic converter ( upstream sensor ) Sensor # 2 would be after the catalytic converter ( downstream sensor )
There is no sensor three on this car. Sensor one is pre catalyst, sensor two is post catalyst.
On a 2004 Lincoln LS ( 3.0 liter V6 and 3.9 liter V8 engines ) Bank 1 is the passenger side of the engine Sensor 1 would be close to the engine before the exhaust enters the catalytic converter
Bank 2 is the drivers side of the engine in your Mercury Mountaineer ( V6 + V8 ) Sensor 1 is in the exhaust close to the engine before the exhaust enters the catalytic converter
Bank 2 is the drivers side of the engine on your 2004 Ford F-150 Sensor 1 would be in the exhaust before the catalytic converter ( upstream ) Sensor 2 would be in the exhaust after the catalytic converter ( downstream )
Trouble code P0340 means: Camshaft Position Sensor A Circuit (Bank 1 or single sensor)
