An auto xray scanner can determine if a O2 sensor is bad.
Just downstream after the exhaust manifold
if i have no cats on my 1990 ford f150 do i leave the o2 sensor unplugged or plug it back up
engine light comes on and off. when light is on it hesitates and transmission slips. what could cause that on a 93 F150
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.
Usually in the exhaust pipes coming off the manifolds
drivers side of engine , downstream from catalytic converter
Most oxygen sensors are in the exhaust pipe....between the exhaust manifold and the catalytic converter.
They are located on the passenger side. Sensor1 is right past the exhaust manifold, and sensor 2 is after the cat.
It stands for IAT sensor 1 Circuit High Input basically there is either a shortin the wiring or the sensor is bad. It is a sensor for intake air temperature and it will effect idle and misfire
How do you check cool temp sensor on a 5.8l f150?
