2006 Pontiac Vibe, short in o2 sensor circuit (p0138)

Showing 4 out of 10 Posts | Show 6 Hidden Posts
Question From nugentc on 2006 Pontiac Vibe, short in o2 sensor circuit (p0138)

Hi. I have a 2006 Pontiac Vibe with 132,000 miles (engine 1.8 L Inline 4-cylinder). I recently got CEL codes p0136 and p0138 so I changed the rear oxygen sensor. CEL was still on afterward and I didn't know I needed to manually clear the codes, so I went to have them read--still p0136, 0138, but then p2195 in addition. Then I learned I had to clear the codes myself.

After I did this, within a day, CEL came back on and p0138 is the only current code. I have checked the 3 fuses for EFI under the hood but don't know what else to check. Apparently this code error is related to a short to battery voltage in the 02 sensor circuit.

Any ideas about how to find and fix my problem?
Thank you!

Response From Hammer Time

No, that's not what that code means at all. It means the sensor is reporting higher voltage than it should. That can mean there is a problem in the circuit, an air leak in the exhaust or it could also mean the fuel mixture is too rich. It needs to be diagnosed properly.

Response From nugentc

Here is where I found information for that code to diagnose the problem:

link deleted

It says one of the following is a problem:

Faulty O2 sensor Short to battery voltage in O2 sensor signal circuit High fuel pressure (not as likely)

links deleted .......... not allowed

Response From Discretesignals Top Rated Answer

Something worth checking out:

TSB #10-06-04-010: Intermittent MIL/Check Engine Light
On, DTCs P0607 and/or P0138, Vehicle Stability Control
Lamp On, Driveability Concerns in High Ambient
Temperatures with A/C On (Clean HO2S Connector and
Inspect...) - (Jul 22, 2010)
Condition
Some customers may comment on an intermittent MIL/check engine light and/or an illuminated
vehicle stability control light. They may also comment about driveability concerns in high ambient
temperatures with the A/C on.
Upon further diagnosis, a technician may find DTC P0607 and/or P0138.
Cause
This condition may be caused by water leaking from the evaporator onto the electrical connector in
the center IP area. The evaporator drain may be restricted, causing water to drip from the
evaporator case onto the post HO2S connector. This creates a path for current to flow from the
heater circuit to the HO2S signal circuit. There may not be carpet wet from this leak, only the
connector.
Correction
Note: The drainage from the HVAC case may not be extensive enough to cause wet carpet or
other damage.
1. Remove the side IP panel then move the carpet back to gain access to the HO2S
connector.
https://docs.google.com/open?id=0B2PjrDSTKD_Mb1dDOFNodGlMOHM
2. Locate the HO2S connector. Clean the connector with compressed air and apply a
small amount of silicone grease to the connector.
https://docs.google.com/open?id=0B2PjrDSTKD_MeUVZVGhMaS0yY0U
3. Locate the HVAC core box. Inspect for moisture in that area. If moisture is present, it's
possible that a plugged evaporator drain tube may be the issue.
https://docs.google.com/open?id=0B2PjrDSTKD_McmVhdW5VNHZORTA
4. Install the carpet back and reattach the IP side panel.
5. Inspect for a plugged evaporator drain tube. Force compressed air up the drain hose to
remove excess water. Drain until a steady flow is achieved and the blockage is cleared.
6. Test drive the vehicle then inspect the evaporator drain tube to verify if it is operating
correctly.

Response From nugentc

Thanks, Discretesignals. When I installed the new sensor there didn't appear to be any moisture on the connector or around the area. We're at a point now that it's not hot out and we're not using AC. I can still check the evaporator drain tube, though.

Response From Discretesignals

Do you have a scan tool that can read data stream information or a digital volt meter?

Response From nugentc

My multimeter (although it's not digital) is back in storage in another state. I don't have a scan tool, but the guy at Autozone supposedly read the voltage from the code reader itself for me.
Here were the readings I copied down:

O2S12: .055
O2S11: ranged from 3.2 to 3.5 and perhaps a little higher at times

Response From nugentc

I just found this document (although the link may get deleted after I post? Not sure the rules on that). Since I did have both p0138 and p2195 at one time, maybe it applies?
So even though p0138 is for Sensor 2, it says to replace Sensor 1. What do you think?



It basically says:
Bulletin Starting Point for Both DTC P0138 and P2195 Set Together

If both DTC P0138 and P2195 are set, replace the HO2S Sensor 1.

Response From Hammer Time

I'm letting that link stay because it's just a TSB but here are the FORUM RULES of what is allowed.

That TSB also states the the computer needs to be reprogrammed in addition to replacing the sensor.

Response From nugentc

I just wanted to post an update and some follow-up for anyone else struggling with the same issue. I checked the evaporator drain tube as suggested above and it's actually not located anywhere near the O2 sensor connector in my Vibe. I might have read somewhere else that the TSB related to that is for AWD. I also checked for exhaust leaks and vacuum hose leaks. I went to have the codes read again and was getting the p2195 in addition to p0138.

There were many online forums and several other sources including the TSB I posted indicating that this combination of codes is due to a faulty O2 sensor 1.

So I changed that out on Saturday, have driven it a lot since then, and the light has not returned.

I hope this is helpful to someone else!

1998 Pontiac Sunfire, codes 0172 and 0404

Question From chrisser on 1998 Pontiac Sunfire, codes 0172 and 0404

1998 Pontiac Sunfire, codes 0172 and 0404. I have replaced the egr valve and the o2 sensor. The same codes keep returning. What else should be looked at?

Response From Discretesignals

Which engine are you dealing with? 2.2 or 2.4?

Response From chrisser

2.4

Response From Discretesignals

P0172 is fuel trim rich code. Means the PCM is seeing a rich condition and is trying to compensate by leaning out the engine.

You really need an enhanced scan tool to monitor fuel trim readings at different rpms, coolant temp, injector pulse width, MAP sensor voltage, O2 voltage, loop status, etc. to diagnose this kind of problem

Some things that could cause that are:

Restricted air filter
High fuel pressure
Leaking injector
Leaking fuel pressure regulator on vacuum side
MAP sensor vacuum hose disconnected or rotted off
Stuck rich O2 sensor

Vacuum leak, unless the leak is huge, will make the engine run rich on those because it is a speed density based injection system.


The P0401 EGR Flow insufficient could be caused from:

Restricted or carboned up EGR feed or outlet passages.
Wiring problem for EGR ground, power or position circuits.
Faulty PCM not sending power when EGR is commanded.

It's possible the MAP sensor could be a problem, if it has no vacuum input, because part of the EGR diagnostics uses the MAP voltage to determine if the EGR is flowing or not.

Once again a scan tool with bidirectional capabilities to activate the EGR valve and monitor isn't position would make diagnosing this problem a whole lot easier.

Response From Hammer Time


The P0401 EGR Flow insufficient could be caused from:

Put the glasses on DS. It's not a 401

Response From Discretesignals

Oops..once again I try to make the perfect post and screw that up...LOL.

P0404 means the PCM is seeing a difference between the desired and actual position of the pintle in the EGR valve.

You'll still need a scan tool to see what the PCM is seeing as a pintle position and to command the EGR to check the position sensor's voltage changes.

Check the wiring really good at the EGR valve. Looked for broken wiring in the insulation at the EGR electrical connector. If you have a meter check for 5 volts on the grey wire with the ignition turned on with the connector unplugged from the valve. You should see close to 0 ohms on the black wire. You should see 0 volts from the PCM on the brown wire.

Response From chrisser

Here's what I got:
Reference negative battery terminal, ignition on
red - 12v
Grey - 5v
brown - 0v
Black - 0v
Black/ white stripe - 0v

Black - 0ohms

Now what?

Thanks

Response From Discretesignals Top Rated Answer

You have gone as about far as you can. You need a scan tool that can command the EGR valve to check pintle positioning.

Question From Guest on 2000 pontiac montana misfiring power loss?


I have a 2000 Pontiac Montana that is losing power going uphill,hard to start, misfiring and backfiring but only occasionally. twice the o2 sensor code came up but they also suspect the cat converter they have said that we can't just do the o2 sensors because if it turns out to be the cat convereter they will have to replace EVERYTHING(Including o2) all over again, IS there any way to tell if it is the converter without cutting it out???!!! is it true I cannot just do the o2's??? I cannot afford to get $1,000 worth of work done if it is only the o2's, and NOT the cat, help anyone??? this is my only transportation!!

Response From flgmtech1

Federal Emissions warranty your Catalytic Converter for 8 years or 80,000 miles as well as your PCM or ECM.
If your 2000 has less than 80K or in service is under 8 years you are stille eligible for coverage at no cost to you.
Also, in todays market GM is offering Goodwill warranty on allot of repairs. If you maintained the vehicle and are not far out of the federal coverage of 8/80K the Dealer it is a viable option for the service manager to approve good will coverage.
I recommend persuing this option if you so desire.

Response From gazskiman

How many miles is on it? Are you losing any coolant?

Response From dave284 Top Rated Answer

Have you checked the timing? And maybe a emission's test on the exhaust could give an idea of the converter's condition
