08 F53 O2 sensor

[billyb]

anyone know what oxygen sensor is the heated sensor. my diagnostic tester says , bank 1, heater sensor. anyone know how many heated o2 sensors it has

I may not be up to date with the O2 sensors but it is my past understanding that the heated sensors had more wires. I do remember this. When the sensors first came out late 70's and for sure by 1980 they only had one wire. As they got hot they generated up to a volt of electricity based on the amount of oxygen generated and passing through the sensor. Later heated sensors had 2 wires on them.

I'd just check the wires going to the different sensors. If you have sensors with one and some with two bank on it that the two wired ones are heated.

What is the code? Most times it is not the sensor but something upsteam.

billyb,
More specific information about your engine will be required, but I assume your ford is a 2008 and a V8. In that case I would very surprised if it does not have a heated O2 sensor, as these are almost always used in these later vehicles and used to bring the internal exhaust components up to temperatures quicker, so the emission and fuel system goes into closed loop faster and consequently reduces exhaust emissions being emitted into the atmosphere.

For many years, the automotive industry has been using two O2 sensors for each catalytic converter, and there will be a converter for each bank of your V8 engine, one being called the upstream sensor (in front of the converter), and a downstream sensor (behind the converter).

As for position of location of the sensors, generally speaking the bank identity is related to the side the #1 cylinder is on, so in the case of your Ford, it should be the Passenger Side of the vehicle.

But, prior to doing much work, you should analyze your system with a OBDII scan device to find out what active and pending codes have been set in you PCM (powertrain control module) better known as the computer. Because there likely other things that can influence O2 code, and an O2 sensor may not be the actual cause of the check engine light coming on.

These O2 sensors are readily available from parts supply houses, ie O'Reillys, Auto Zone, NAPA, ETC., and with motorhomes, you may have to advise them that it is for a bare chassis, since it is not specifically a common F150, F250, etc.

Hope this helps in your efforts.

Happy RV'g

The failure in the heater circuit on o2 sensor is very common. We replace a few every month. It is almost always the sensor itself, every once in awhile we will find the wiring has melted on the exhaust and blown the fuse but besides that its pretty much a quick and easy fix.
