SOURCE: O2 sensor problem

I have a 97 gmc sierra .This truck is the same as the chevy ok.Its a 350 5.7 liter 4x4 Z71.I took it to auto zone which was my first mistake.They put it the scanner and said bad O2 sensor.Ok so which one is it i said.They dont know.Well there four (4) O2 sensors in this truck i hope you know that.I had to replace all four of them before i had to take it to a real shop.It seems the fuel pump i replaced a week earlier with an auto zone fuel pump was bad.Ive changed my feul pump 4 times now and have 235000 miles on still running.You need to get your fuel pressure checked.It should be 65 psi to start it and 55 psi to run it.If the pressures are good it could be a different O2 sensor or maybe the mass air flow senor.My last option would be the fuel pressure regulator because it seems to be a waste of time and money.I would get that fuel pressue checked first.Good luck.

SOURCE: 2002 chevy silverado hd2500 6.0 ecm code po332 low

If all connections are good "dry, tight, no corrosion" then yes. It should be a defective sensor. These sensors are piezo sensors and create a voltage when sensing a knock. A bank refers to a side on a V style engine, 2 refers to the rear sensor on your bank 2. Bank 1 should be the side with cylinder #1 which should be the cylinder closest to you on one of the sides. So your looking for the rear sensor on the opposite side.

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

My2000 mercury cougar has code 156&161 what could be the problem


error codes p0156 (02 sensor circuit malfunction) ( bank 2 sensor 2) &
p0161 (02 sensor heater circuit) (bank 2 sensor 2 ) are related. The faulty heater in the sensor will cause the PO156 to set as well. Bank 2 sensor 2
will be located on the drivers side after the converter.

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.

I have error codes p0156 p0161


  Check the wire harness near the top of the engine in the rear. They were good for rubbing through on the trans fill tube bracket. Judging by the code you have 4 sensors. you would be interested in the drivers side rear sensor.
