#1 is the drivers front. The O2 your looking for is on the drivers side after the catalytic converter. You can certainly try to repair the wire. If you use a **** style connector make sure it is one with a heat shrink wrap to protect the wiring from corrosion. The best repair would be to solder the connection and then shrink wrap the joint. If the repair doesn't work you're only out a couple of bucks.

  • O2 Sensor Heater Circuit Malfunction - Bank 1 - Sensor 1
  • Basically the ECM Electronic Control Unit has determined your O2 sensor is taking to long to begin reacting properly.
  • The causes could be
  1. O2 heater element resistance could be to high.
  2. An internal short or opening in the heater element.
  3. O2 heater circuit wiring with high resistance.
  4. Open or short to ground in the wiring harness.

  • The fixes are
  1. Check the harness and connector to the O2 sensor for shorts or ground.
  2. Replace that O2 sensor.

  • Bank 1 sensor 1 location for this vehicle is located on the exhaust manifold back by the firewall on top of the manifold..

I have research around and found that the Bank 1 sensor 3 O2 sensor is post Cat. But when I got under there I dont see anything that could resemble a sensor. Where is it. Please help. Marc


try this
ALLDATA Editor's Note: Always verify #1 cylinder location prior to diagnosis and repair.

- Cylinder bank number one is the bank that contains number one cylinder.


See: Firing Order

Cylinder #1 on right side.

- The first oxygen sensor in cylinder bank # 1 is numbered O2 Sensor 1/1.
- The second oxygen sensor in cylinder bank # 1 is numbered O2 Sensor 1/2.
- A third oxygen sensor in cylinder bank # 1 would be numbered O2 Sensor 1/3.
- The first oxygen sensor in cylinder bank # 2 is numbered O2 Sensor 2/1.
- The second oxygen sensor in cylinder bank # 2 is numbered O2 Sensor 1/1.



- If a V-6 or V-8 vehicle only uses one downstream Heated Oxygen Sensor (HO2S) it is numbered O2 Sensor 1/2, even if it uses two upstream HO2S.

The code that comes up is p0141. the book says that it is a O2 sensor heater malfunction. But the book does not show me where the O2 sensor heater is located. I'm confused. I have located the 02 sensors. 4...


P0141 is O2 Heater Circuit (Bank 1, Sensor 2) It will be the sensor AFTER the cat on the side that has #1 cylinder. On your car it's the PASSENGER side.

CODE PO155 BANK2 SENSOR 1 WHERE IS THIS SENSOR LOCATED?


A code P0155 may mean that one or more of the following has happened:
* O2 Heater element resistance is high
* Internal short or open in the heater element
* O2 heater circuit wiring high resistance
* open or short to ground in the wiring harness

Possible Solutions:
* Repair short or open or high resistance in wiring harness or harness connectors
* Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)


Oxygen sensors are always numbered like this:
Bank 1 sensor 1
Bank 2 sensor 1
Bank 1 sensor 2
Bank 2 sensor 2

Some manufacturers use a kind of shorthand that reads different, but means the same thing:
Sensor 1/1 or O2s 1/1
Sensor 2/1 or O2s 2/1
Sensor 1/2 or O2s 1/2
Sensor 2/2 or O2s 2/2

Bank 1 is always the side of the engine where cylinder number 1 is located and, of coarse, Bank 2 is the opposite side.
On a 4 cylinder engine, there is only 1 bank and it is always referred to as Bank 1.

Sensor 1 is always the upstream sensor (The one located BEFORE the catalytic converter)
Sensor 2 is always the downstream sensor (the one that is located AFTER the catalytic converter.

Hope helps (remember to rate this).

Error code p0032 on 2004 dodge caravan. what is the code?


Hi.

P0032 means HO2S Heater Control Circuit High (Bank 1 Sensor 1).

It means high impedance from O2 sensor, check wiring to sensor and replace the sensor.
Check O2 sensor located in bank 1 (cylinder 1 side- see here), and after the catalitic converter (there is also an O2 sensor before cat converter).
