Oxygen Sensor Heater Codes - Many!


Recommended Posts

Posted

2006 Sierra 1500HD 6.0L

 

P0036 - Heated Oxygen Sensor (HO2S) Heater Control Circuit Bank 1 Sensor 2

P0056 - O2 Bank 2 sensor 2 Heater control circuit

P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)

P0161 - Oxygen O2 Sensor Circuit Low Voltage (Bank 2, Sensor 2)

P0054 - P0054 HO2S Heater Resistance (Bank 1, Sensor 2)

 

The passenger side (bank 2 I believe?) sensor was replaced about 6 months ago with a Walker unit. It was throwing a P0056 code at the time. Now that is back, with many others. Is there a ground that the heater circuits ground though that could cause this? Any other suggestions?
