I have a 2001 chrystler sebring coupe lxi 3.0 where is my oxygen sensor its reading bank1 sensor2 pl let me know where to locate this sensor location thnks

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 is possible it is in the passenger side exhaust manifold.

There should be a diagram somewhere under hood. If not, check shop manual (might be able to just look at one a parts store if you feel it is too expensive to buy).

P0136 = Oxygen Sensor Circuit Malfunction (Bank1, Sensor2)
P0141 = Oxygen Sensor Heater Circuit Malfunction (Bank1, Sensor2)

CHECK WIRING BEFORE REPLACING SENSORS

If 4 cylinder engine, there are only two O2 Sensors - Sensor 1 is on top, Sensor 2 is at the bottom

If 6 cylinder, there are four (4) O2 sensors (Bank1, Sensor2 is on the firewall side of this engine and is referred to as the 'DOWNSTREAM' sensor (the one AFTER the Catalytic Converter)

P0138 - Oxygen Sensor Circuit High Voltage (Bank1, Sensor2)

P0139 - Oxygen Sensor Circuit Slow Response (Bank1, Sensor2)

The Heated Oxygen Sensor (1 or 2) located rear of catalytic converter produces an output signal relative to oxygen storage capacity of catalytic converter. Ho2S 2 signal is less active than signal produced by front oxygen sensor. This code sets when HO2 Sensor voltage is greater than 999 mV for more than 2 minutes (time depends on model. Could be as high as 4 minutes)

Symptoms: There may be no noticeable symptoms except for MIL illumination. Possible high fuel pressure can over rich the system.

Causes: A code P0138 may mean that one or more of the following has happened:
* Faulty O2 sensor
* Short to battery voltage in O2 sensor signal circuit
* High fuel pressure (not as likely)

Here are some potential solutions:
* Replace O2 sensor
* Repair short to battery voltage in o2 sensor signal circuit

Hope helps (remember to rate this answer).

Bank1 refers to the driver's side of the engine, so follow the manifold from the engine back towards the catalytic converter, sensor1 will be before the cat and sensor2 will be after the catalytic converter.

Bank one sensor is going to be in the front of your catalytic converter and bank two will be to the rear of it. This way your ECM knows how well the cat is working. It will read the oxygen content before the cat and then after.

There are 4 oxy. sensors listed for your truck. they're located as follows
Left exaust before catalytic converter. bank1 sensor1-after cat conv.
bank1 sensor2. right exaust before cat.conv. bank2 sensor1-after cat.
conv. bank2 sensor2. Hope this helps.

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

in the exhaust , behind the catalytic converter.
