On a 2005 Ford F-150 :
( for the 4.2 liter V6 , 4.6 and 5.4 liter V8 engines )
Bank 1 is the passenger side of the engine
Sensor 2 is in the exhaust AFTER the catalytic converter
drivers side of engine , downstream from catalytic converter
They are located on the passenger side. Sensor1 is right past the exhaust manifold, and sensor 2 is after the cat.
Bank 2 is the drivers side of your engine on your Ford Sensor 1 is in the exhaust before the exhaust enters the catalytic converter
where is the crankshaft position sensor a bank 1 circuit malfunction on a 2003 f150 at
it is located on the passanger sideand its the one befor the cat converter ----------------------------------------------------------------------------------- actually , bank 2 is the drivers side of the engine
On your Ford F-150 : Bank 1 is the passenger side of the engine Sensor 1 is somewhere in the exhaust close to the engine before the exhaust enters the catalytic converter ( upstream )
Removing the transmission dip stick will give you more room to work, but it's still a hard place to get to.
An auto xray scanner can determine if a O2 sensor is bad.
Just downstream after the exhaust manifold
bank 2 is the drivers side of the engine sensor 2 is after the exhaust has passed through the catalytic converter ( downstream )
system to lean bank one 02 sensor ?
Bank 1 is the passenger side of the engine Sensor 2 is after the exhaust has passed through the catalytic converter ( downstream )
