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

P0161
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). Symptoms There will likely be no obvious symptoms other than MIL illumination. Causes 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 Possible Solutions Replace HO2 Sensor Repair open or short in power circuit Repair open or short in ground circuit Repair damaged connector due to tracking

As for the 0303 or the 0300 these are probably just side effects of the 0161 fault But the 0303 code means the Cylinder #3 misfired and the 0300 means that you have a bunch of random misfires going on.Make sure you go back over the engine and check all the wiring, you may have disconnected or busted a wire while changing plugs.
