2008 Aspen 02 sensor code

[cathyzirkle]

I have a 2008 Aspen and the check engine light has been coming on intermittently for a year. I replaced 1 of the 02 sensors that looked bad. the others looked ok. Now it has been very hesitant when i first drive it. feels like its going to stall out. I had it scanned for codes and it came up with 8 codes: p0161, p0135, p1128,p0058, p0300, p0032, p0038, p0052. Please help

p0161 -- O2 SENSOR 2/2 HEATER PERFORMANCE
p0135 -- O2 SENSOR 1/1 HEATER PERFORMANCE
p1128 -- CLOSED LOOP FUELING NOT ACHIEVED - BANK 1
p0058 -- O2 SENSOR 2/2 HEATER CIRCUIT HIGH
p0300 -- MULTIPLE CYLINDER MISFIRE
p0032 -- O2 SENSOR 1/1 HEATER CIRCUIT HIGH
p0038 -- O2 SENSOR 1/2 HEATER CIRCUIT HIGH
p0052 -- O2 SENSOR 2/1 HEATER CIRCUIT HIGH

Lots of potential causes for all of these, from O2 sensors (obviously), to fuel delivery, to electrical, to PCM, to heater ground circuit, to...

Which codes did it start with a year ago when you first got the light?

all 4 o2 sensors share the same G100 ground for the heater circuit ground

Originally it came up with p0032 so we checked them and the front left was bad so we replaced it. The engine light stayed off for a little while then came back on.
