Oxygen sensing related issues

I have been trying to diagnose the the cause of my check engine light and I have not have much luck in a solution. With these codes I had initially replaced all 4 oxygen sensors since I was past 80,000 miles anyways. Codes returned and persisted during smog. The wiring and fusing was tested and confirmed to be correct leaving to the PCM to be the potential issue. I contacted SIA electronics for a refurbish and they mentioned needing to rebuild the O2 circuit along with a software update. Unfortunately, the codes have returned only a week after the repair and I am unsure what else I can do at this point. If I flash the codes they all return during the next cold start. Looking at some of the codes such as having P0051 and P0052 don't make sense. How can a sensor read both high and low? Any ideas?


Vehicle: 2006 Jeep Wrangler 6 cylinder with 6 speed manual


ODBII Codes:


P0032
P0031
P0038
P0032
P0051
P0052
P0057
P0058

What year is your rig? Did you install OEM sensors or an aftermarket brand like Bosch?

looking at the list of codes, the same o2 HEATER elements are reading HIGH and LOW,
IDK -
You will need a SCANNER to look at this, lookiing at freeze frame etc, And a wiring diagram.


P0031-O2 SENSOR 1/1 HEATER CIRCUIT LOW
P0032-O2 SENSOR 1/1 HEATER CIRCUIT HIGH
P0038-O2 SENSOR 1/2 HEATER CIRCUIT HIGH



P0051-O2 SENSOR 2/1 HEATER CIRCUIT LOW
P0052-O2 SENSOR 2/1 HEATER CIRCUIT HIGH
P0057-O2 SENSOR 2/2 HEATER CIRCUIT LOW
P0058-O2 SENSOR 2/2 HEATER CIRCUIT HIGH


You clear the codes, have you erased the RAM that is nothing more than removing NEG battery cable. TRY that and advise what codes reappear.

When I see the price of OEM I think aftermarket.

I did clear RAM via battery disconnect. These where the codes that returned. As for more detail with a scanner, that sounds like an investment. I will look for someone that can confirm the codes.

This issue is confusing as the codes suggest a low and high condition on the same sensor. It has me thinking an intermittent problem.
Do you have a remote starter, added alarm, do you keep anything plugged into DLC? Anything modified ie exhaust, programmer, chips, proms ?

Also are there ANY other codes?

Those codes are not for the O2 sensor itself, but the O2 sensor heaters.

NGK (NTK) was the OEM manufacturer of the O2 sensors for Jeep.

Check all the O2 sensor wiring.

If I remember correctly, the heaters are driven by the PCM. So, hopefully you find a wiring issue.

Jeep is stock and these are all of the codes listed.

lets take a look at G105, a common ground for all sensrs AND jeep grounds are a known issue.

Ground had good contact. The only modification I had was related to replacing the oxygen sensors and the PCM rebuild.

OK next thiughts
Lets see if the splice for the o2 sensors is OK.
Do you still have the original PCM?

Only because it s so simple test the ALT diodes. And I will think of simple easy tests to work thru this.

You know, I'd probably just throw a digital multimeter on the heater wires to check to see if you have current.
