How many oxygen sensors does a 2001 Chrysler Sebring have with the 2.7 liter engine

Their are 2 oxygen sensors on your 2.7 engine,here's a link showing you them. https://www.autozone.com/repairinfo/repairguide/repairGuideContent.jsp?fromSearchPage=true&pageId=0996b43f802d6afa&partName=Heated+Oxygen+Sensor&partId=0996b43f802d6afa&repGuide=VehicleRepairGuides-Avenger,+Sebring+Coupe,+Stratus+Coupe,+1999-2006-null

It should be alright for a bit. It will not cause damage. Your gas mileage may drop a bit. The oxygen sensor is there for the computer to adjust fuel requirements for the engine, called "fuel trim"-more precise measurement of the gas required to run at optimum.

bank 1: exhaust manifold by firewall
bank 2: after catalytic converter

Hi,

Location of oxygen sensor: Under hood, center, rear engine area, mounted in exhaust manifold

Hello, Eventually your Chrysler Sebring's oxygen sensor will go bad and need to be replaced. The oxygen sensor regulates the oxygen-to-fuel ratio in your vehicle. It also controls your gas mileage. It senses when more or less oxygen needs to be pumped into the fuel lines. If it fails, your Sebring will run poorly and won't get very good gas mileage. Knowing how to change it yourself can save your money. Here are the instruction to change o2 sensors.
Locate your Sebring's oxygen sensor on the pre-catalytic converter. This is located near the front right wheel well of your vehicle. Apply some anti-seize paste to the threads of the new oxygen sensor. Be careful not to get any of the paste on the sensor itself, or it will be ruined. This makes for easy removal of the sensor next time.Remove the old oxygen sensor, using the 7/8-inch wrench. Find the stock sensor wire near the engine-loop lift. This will be by the firewall of your Chrysler Sebring. Splice the stock sensor wire and connect it to the new oxygen sensor's wire, using crimp connectors.Remove the large air-intake pipe that runs from the air box to the rear turbo. Then remove the two smaller air pipes that run from the air box to the blowoff valves. This will give you access to the oxygen sensor. Soak the old oxygen sensor in WD-40 to loosen it. Screw in the sensor by hand. Use the wrench to fully tighten the oxygen sensor so it cannot be removed by hand. Replace the air pipes to the correct valves again.

Rate me if you like my answer..

Thanks

the only sensor that would be on your manifold would be the o2 sensor ihave an intrepid i have four, two converters. 1 before each converter and 1 after each converter. fronts are 1s and backs are 2s all are 4 prong maybe your backs are threes you will need to investigate a little more after all we are dealing with pretty much the same car same year

Bank 1 is the exhaust manifold at the firewall, sensor 2 is the O2 sensor after the catalytic converter.

(Fuel filter will not effect anything, it only prevents build up in engine)
Could be one of these-
Oxygen sensor
fuel sensor
Dirty injectors
Bad injector/injectors

~~~~Go to car zone/ or a frendly auto part store, and ask them for a FREE electronic computer check ( where they check the computer, and the computer tell them whats wrong)

I hope help you with this (rated this help). Good luck.
