Just downstream after the exhaust manifold
An auto xray scanner can determine if a O2 sensor is bad.
Disconnect the battery. On the side of the throttle body, disconnect the wiring from the position sensor. Remove the bolts from the sensor, and lift the sensor off, reverse the procedure to install the new one.
what eng. do you have? if it is a 5.4 or a 4.6 it is under the intake manifold on the passenger side.
Just ground the wire with a screw straight on to the frame!
engine light comes on and off. when light is on it hesitates and transmission slips. what could cause that on a 93 F150
Usually in the exhaust pipes coming off the manifolds
drivers side of engine , downstream from catalytic converter
Near the starter on the exhaust header. If it is 1990 it will be fun to break the rusty sensor out of the truck. good luck
How do you check cool temp sensor on a 5.8l f150?
1986 f150 emisson light on is their restn set
Most oxygen sensors are in the exhaust pipe....between the exhaust manifold and the catalytic converter.
