On a Ford, Bank One is the cylinder head with cylinder #1, #2, #3 cylinders.Bank 2 is the other cylinder head with cylinders #4, #5, #6. O2 Sensor's 1 are between the exhaust manifold and the Cats. O2 sensor's 2 are after the Cats. An general rule of thumb to identify cylinder #1 or bank 1, look at the engine from the drive belt end. See what cylinder head is closer to the drive belt, That is bank 1. The cylinder closest to the drive belt in that head is cylinder #1.
I hope this helps.

Bank 2, sensor 2 is at the bottom of the engine as you look in from the bumper. It is installed in the exhaust pipe just below the catalytic converter. The bank 1, sensor 2 is at the same location on the back of the engine below the firewall.

I replaced o2 bank 1 sensor and still getting p1148 closed circut 02 bank 1 code


Im curious if you had code erased after replacing the sensor? Simply by replacing the sensor will not reset the computer. You must have someone (Autozone) to check it and reset the computer. This takes a matter of seconds to a minute to hook a handheld comp. called an OBD2 into the vehicle under the dash. It will read the code and display the code, Then have them erase the code to see if it reappears.

1997 plymouth voyager w/ codes: P0140 O2 sensor circuit no activity detected (bank 1(2) sensor 2


The Powertrain control module (PCM) will provide a .45 volt reference voltage to the Oxygen sensor. When the O2 sensor reaches operating temperature, it will generate a voltage that will vary depending on the oxygen content of the exhaust. Lean exhaust generates a low voltage (less than .45V) and rich exhaust generates a high voltage (greater than .45V). O2 sensors on a specific bank marked as "sensor 2" (as this one is) are used to monitor emissions. A Three-Way Catalyst (TWC) system (catalytic converter) is used to control tailpipe emissions. The PCM uses the signal received from Oxygen sensor 2 (#2 indicates aft of catalytic converter, #1 indicates pre-converter) to read efficiency of TWC. Normally this sensor will switch between high and low voltage at a noticeably slower rate than the front sensor. This is normal. If the signal received from rear (#2) O2 sensor indicates that the voltage has "stuck" between .425V to .474 V, the PCM determines this sensor is inactive and this code will set.
Potential Symptoms Your check engine light(CEL), or malfuction indicator lamp (MIL) will be illuminated. There will not likely be any noticeable drivability problems other than the MIL. The reason is this: The rear or post catalytic converter Oxygen sensor does not affect fuel deliver(this is an exception on Chryslers). It only MONITORS the efficiency of the catalytic converter. For this reason, you will likely not notice any engine trouble.
Causes The causes for a P0140 code are fairly few. They could be any of the following:
  • Shorted heater circuit in O2 sensor. (Usually requires replacement of heater circuit fuse in fuse block also)
  • Shorted signal circuit in O2 sensor
  • Melting of harness connector or wiring due to contact with exhaust system
  • Water intrusion in harness connector or PCM connector
  • Bad PCM
Possible Solutions This is a fairly specific problem and shouldn't be too difficult to diagnose.
First, start engine and warm up. Using a scan tool, watch the Bank 1, sensor 2, o2 sensor voltage. Normally the voltage should switch slowly above and below .45 volts. If it does, the problem is likely intermittent. You'll have to wait for the problem to surface before you can accurately diagnose.
However, if it doesn't switch, or is stuck then perform the following: 2. Shut off vehicle. Visually check the Bank1,2 harness connector for melting or chafing of the harness or the connector. Repair or replace as needed 3. Turn ignition on, but engine off. Disconnect the O2 sensor connector and check for 12Volts at the Heater Circuit supply and for proper ground on the heater circuit ground circuit. a. If 12V heater supply is missing, check the proper fuses for an open in the circuit. If heater circuit fuse is blown, then suspect a bad heater in the o2 sensor causing a blown heater circuit fuse. Replace sensor and fuse and recheck. b. If ground is missing, trace the circuit and clean or repair ground circuit. 4. Next, with connector still unplugged, check for 5 Volts on the reference circuit. If this is missing, check for 5 Volts at the PCM connector. If 5 Volts is present at the PCM connector but not at the o2 sensor harness connector, then there is an open or short in the reference wire supply between the PCM and the o2 sensor connector. However, if there is no 5 Volts present at the PCM connector, the PCM is likely at fault due to internal short. Replace PCM. ** (NOTE: on Chrysler models, a common problem is the 5Volt reference circuit can be shorted out by any sensor on the car that uses a 5 Volt reference. Simply unplug each sensor one at a time until the 5 Volts reappears. The last sensor you unplugged is the shorted sensor. Replacing it should fix the 5 Volt reference short.) 5. If all the voltages and grounds are present, then replace the Bank 1,2 O2 sensor and re-test.

I pulled codes with a OBDII code reader and it gave me three codes. (1) P1166- Primary HO2S (No.1) Heater System Electrical. (2) PO134- O2 Sensor circut no activity detected (bank 1 Sensor 1). (3) PO845-...


You have a burned Oxygen sencer, and the transmission pressure sencer is bad also. Your heater has a bad switchover circuit. Hope this helps.

This is Bank 1 (closer to the dash panel) Sensor 2 (located after the catalytic converter).

---
Note: A malfunctioning front oxygen sensor may cause fuel trim codes to set.
  1. Several Diagnostic Trouble Codes use specific terminology to refer to sensor location. The illustration and key below explain the following terms:
  2. Engine BANK Bank 1 is closer to the dash panel, (also referred to as RH or right hand). Bank 2 is closer to the radiator, (also referred to as LH or left hand).
  3. UP Refers to Sensor 1 or "front sensor". It is located closer to the exhaust manifold and before the catalytic converter.
  4. DOWN Refers to Sensor 2 or "rear sensor." It is located after the catalytic converter.
  5. The following examples show how to interpret oxygen sensor terminology:
  6. B1/S1 = Bank 1/Sensor 1 = Dash panel side, BEFORE the catalyst or "upstream"
  7. B2/S2 = Bank 2/Sensor 2 = Radiator side, AFTER the catalyst or "downstream"

Code po141 heater circut sensor/where do i find this sensor? where is bank 1


code is not for heater circuit,
code p0141=O2 Sensor Heater Circuit Bank 1 Sensor 2
that means its an oxygen sensor located in bank 1 which is the drivers side,sensor 2 means its the downstream sensor after the convertor

check the wiring to the bank 2 sensor, that is the one behind the catalytic converter on the opposite side from the bank where #1 cylinder is located, see firing order diagram below.
