Cant find base1 sensor2 on a 96 ford explorer 6 cylinder 4 wheel drive


It's called bank, not base. On a v6 or v8, each side of the engine is called a bank. Bank 1 is always the side where the number 1 cylinder is located. On Fords, number 1 is on the right bank or side, the right as if you were sitting in the vehicle, so well, the passenger side.
Sensor 2 is the oxygen sensor in the exhaust stream after the catalytic converter (somebody recently called it the cadillac converter!). You have two oxygen sensors on the right bank, one before the cat and sensor 2 is after the cat. The only purpose of sensor 2 is so the computer can monitor the efficiency of the catalytic converter. It compares the readings from sensor 1 and sensor 2. Sensor 1 information is how the computer adjusts fuel trim.

How many oxygen sensors are there on a 1996 ford explorer 8 cyl., 4.0 eng.


The answer depends on the type of exhaust system you have. You will have either 3 or 4 total O2 sensors on your V8. If you have single exhaust with a single catalytic converter then you will have 3 O2 sensors (2 upstream sensors & one downstream sensor - "up or down stream" meaning before of after the catalytic converter). If you have either dual exhaust and/or two catalytic converters then you have 4 O2 sensors (2 upstream & 2 downstream). If you have an MIL light (malfunction indicator light, or "check engine light") the code will indicate "front bank / bank one", which is one of the 2 upstream O2's before the catalytic converter(s), or "rear bank / bank two", which is one of the O2's after the catalytic converter(s).

Which is bank 2 for the o2 sensor for post cat?


HiI!!
6 cyl. and 8 cyl. engines are divided into 2 Banks, standing in front of the Engine, the Bank 1 is the side where the #1 spark plug is (on V6 Ford Engines is on the PASSENGER SIDE). Bank 2 is on the DRIVERS SIDE.
Check the following diagram for HO2 sensor locations (This diagram applies to Ranger, Explorer and Mountaineer models) :

2 would be Bank 1 and 2A would be Bank 2.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

I need to replace the bank 1 sensor 1 on a 97 ford explorer. I have found the bank 2 sensor 2, but I can't find the bank 1, sensor 1. Is there anywhere to find a diagram or can it's location be described...


Thanks for trying fixya,

There are 4 sensors, though not all of them are technically called "oxygen sensors. There are two that are upstream of the catalytic converters, one on each bank. Then, there are two more, one after each catalytic converter, that are oxygen sensors, but officially they are called catalyst monitors, because that is the job they are assigned to do.

Bank One would be the left catalytic - trace to left manifold and bank the other.

Location of the bank 1 sensor 2 O2 sensor on a 2001 ford escape


B1 means the sensor is located on the same bank of the engine that has the #1 cylinder. B2 is located on the opposite bank.
S1 means the sensor is located BEFORE the catalytic converter
S2 means the sensor is located AFTER the catalytic converter

You didn't say which engine you have, so I've included the diagrams of both 4 cyl and 6 cyl so you can see the banks

Check engine light 97 ford explorer. obd-II po141 bank 1 sensor 2. need to locate sensor


Looked up your OBD II code for your Explorer and got the following: Bank 1 Sensor 1
The possible causes are listed below per Chilton: *same result for all engines available on your vehicle

Trouble Code: P0141 (4.0L V6 VIN E Auto)
HO2S-11 Heater Circuit (Bank 1, Sensor 1) Print this code dataprint_icon_codes.gif
Number of Trips to Set Code: 2
OBD II Monitor Type: CCM Details
Indicators: MIL Details
Trouble Code Conditions:
During testing the heated oxygen sensor (HO2S) heaters are checked for open and short circuits and excessive current draw. The test fails when the current draw exceeds a calibrated limit or an open or short circuit is detected.
Possible Causes:
  • Vacuum hose disconnected on exhaust gas recirculation (EGR) system module (ESM) applications* Short to VPWR in the harness or HO2S
  • Water in the harness connector
  • Open VPWR circuit
  • Open GND circuit
  • Low battery voltage
  • Corrosion or incorrec
The sensors themselves appear in the illustration linked to below. The illustration is for the Ford Ranger but indications are that other models have similar locations. Hope this helps with your problem. Best of luck!
