Oxygen Sensor...1991 E-250 5.0L...
All,
Not really sure where to post this but its performance related.
I need to know how many o2 sensors I have as I am getting people telling me I have 1 or 2.
Secondly where are they located....I see one on the passenger side exhaust down from the manifold .....but not finding any second one but I wonder why its only on one side (before Y in the exhaust).
Please note I have running boards on this van and this thing is a bear getting under....so its probably me missing the obvious...
Is the other sensor under the dog house....down the exhaust more?
Not seeing two in my electrical diagram either....
Thanks for the help,
chris

If I'm right, the "Speed Density Fuel Injection" has 1 oxygen sensor and the "Mass Airflow" has 2 Sensors.
The sensors are either one per header or in the Y-connection in front of the catalytic converter
