SOURCE: need to know where the

Location of 02 sensors - Bank 1 sensor 1 is on the up stream side of the Catalatic Converter. And Bank 1 sensor 2 is on the down stream side of the Catalatic Converter. Bank 2 sensor 1 is on the up stream side of the Catalatic Converter. And Bank 2 sensor 2 is on the down stream side of the Catalatic Converter.

Where are theOBD O2 sensor heater code po161 for a 1998 chevy. Silverado v 6


That is P0161 (letter "P" and four numbers)
P0161 Oxygen O2 Sensor Circuit Low ( engine cylinder bank 2 sensor #2)
What does that mean? This diagnostic trouble code (DTC) is a generic powertrain code, which means that is applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model.
It basically means the PCM detected either an excessive current draw, or an open or short in the circuit powering the oxygen sensor's heater circuit. This is in reference to the Heated Oxygen Sensor (2) located rear of catalytic converter (Bank 2).
A code P0161 may mean that one or more of the following has happened:
  • HO2S heater power circuit open
  • HO2S heater ground circuit open
  • HO2S signal tracking (due to oil or moisture in the connector)
  • HO2S is damaged or has failed PCM has failed

Hi, I am getting Faulty codes P0036, P0056, P0141, P0161 in reference Bank 1 and Bank 2 for sensors 2 on 2003 CTS.I was told the sensors where changed but codes still appear?


If the sensors were replaced an DTC'S come back has to be a wiring problem or PCM ,
The ECM detects that the HO2S heater low control circuit voltage is between 2.6-4.6 volts when the heater is commanded OFF, indicating an open HO2S heater circuit.
Is the fuse open?
All four codes refer to the heating element circuit ! there is a relay in the under hood fuse box that supplies B+ voltage to the O2 sensor heating elements . I would change that or test the relay , videos on you tube on testing relays .
MAIN Relay

Error code p0161 on ford windstar 2002


Hi there:

This fault code refer at Oxygen O2 Sensor Circuit Low Voltage (Bank 2, Sensor 2), and basically means the PCM detected either an excessive current draw, or an open or short in the circuit powering the oxygen sensor's heater circuit. This is in reference to the Heated Oxygen Sensor (2) located rear of catalytic converter (Bank 2).



A code P0161 may mean that one or more of the following has happened:

  • HO2S heater power circuit open
  • HO2S heater ground circuit open
  • HO2S signal tracking (due to oil or moisture in the connector)
  • HO2S is damaged or has failed PCM has failed


Possble soutions:
  • Replace HO2 Sensor
  • Repair open or short in power circuit
  • Repair open or short in ground circuit
  • Repair damaged connector due to tracking

What the sytoms of a clogged catalic converter?


Classic symptoms of a plugged catalytic converter. You may also have a check engine light, with these codes:

P0160 O2 Sensor Circuit No Activity Detected (Bank 2 Sensor 2)
P0161 O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 2)
P0162 O2 Sensor Circuit Malfunction (Bank 2 Sensor 3)
P0163 O2 Sensor Circuit Low Voltage (Bank 2 Sensor 3)
P0164 O2 Sensor Circuit High Voltage (Bank 2 Sensor 3)
P0165 O2 Sensor Circuit Slow Response (Bank 2 Sensor 3)
P0166 O2 Sensor Circuit No Activity Detected (Bank 2 Sensor 3)
P0167 O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 3)

or simply:

P1484 Catalytic Converter Overheat Detected A catalyst overheat condition has been detected by the catalyst temperature sensor

With the symptoms you are describing though, 99% sure that will be it.

Many times a "clogged" catalytic converter is actually a broken one. Inside the unit, there is a honeycomb-like structure that aids the converter in superheating the exhaust fumes, which cuts down significantly on emissions. Over time, this honeycomb structure can get brittle and crack or chunk off inside the unit, which will impede the flow of exhaust. For this reason, many times a clogged or broken catalytic converter will rattle or make vibrating noises when the engine is given gas.

Dakota 4.7 P0161 code? What does it mean


P0161 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 2)
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.
