2011 CHEVY VOLT CODES U0121,P0AC4,P1E00,P1EA9. DOES THIS FIX IT?

[@BigDog50001]

A bad ground wire can certainly wreak havoc on those modules. Great info Mike, hopefully it was just a loose bolt!

[@TheDisgruntledMechanic]

Yeah but I bet it won't be that easy!

[@SpeakerMan-24in]

@@TheDisgruntledMechanic I tightened these bolts, one wasn't really loose but I could turn it a 1/2 or 3/4 times. Since then I have not had the "engine not available" code Previously mine would have this issue in hard rain after going down a hill and then accelerating hard. The issue is now solved

[@MPDano]

Was there a follow up on this video? It's been a year now, did the codes return? Which side of the trans was this ground strap at? Did you remove a cover or was it already visable? Sorry for all the questions but it will help us out.

[@pontiacsrule8761]

I think you did the right procedure. Then if the codes come back, try plan B with the shorter bolt. Never worked on a volt. Those were some strange code numbers.

[@jimthecarguy]

That bolt looked very loose to me. I hope that takes care of the problem.

[@TheDisgruntledMechanic]

Me too Jim. Thanks

[@mikeguiggey2586]

good call, make sure the missus can get to the farmers market, like both of your videos..👍

[@TheDisgruntledMechanic]

TY!

[@arthurfricchione8119]

Hi Mike. Eventually you will be the go to guy on these volts. Nice to see that your still in the video business. Was thinking of your channel the other day. Mike don’t break that bolt off. Thanks for sharing and stay well and safe. Artie 😊🇺🇸 Mike what scanner are you using? Looks like the think pad diag like Ivan uses?

[@TheDisgruntledMechanic]

The reason I used the 1/4" drive, less chance of snapping off. I am using the thinkdiag app and dongle. I did a video on it awhile ago. Stay safe Artie!

[@stuzman52]

Hopefully, tightening the bolt will take care of the problem Mike!

[@TheDisgruntledMechanic]

Thanks Terry. Well if not I guess it is back to more diagnostics!

[@johnnywatches247]

Nice video and thanks. Going to give it a go on my Volt too. Heard this issue from multiple Volt owners so looking to see if it would fix it. Keep up the good Bro and Cheers😎👍

[@TheDisgruntledMechanic]

TY!

[@dudeitstech]

Did your P0AC4 come back? I have similar codes. Also looking into replacing teh 12V.

[@TheDisgruntledMechanic]

yes but my Volt has more issues than just a battery.

[@hueandsteve1989]

Helpful, thanks.

[@TheDisgruntledMechanic]

You're welcome!

[@txsviking]

It's never an easy fix like that for me. It always ends up being the most expensive thing that could possibly go wrong.

[@TheDisgruntledMechanic]

Oh believe me ain't celebrating yet because I have the same. Stay tuned!

[@scuba422123]

hi mike voltage drop check that bolt was loose... what a cluster of codes

[@arthurrodesiler3109]

Seems like ground wires can give you all kind of headaches. Hope that is all it is even if you have to take it off and clean it.

[@greggamer9032]

If I was going to use my 2013 Chevy Volt as a race only...car can I remove the cats form it or at least the rear one?

[@SteveRobReviews]

It was a bit loose but I'm thinking not loose enough to matter so onto removal of the bolt and a good cleanup next 🤷‍♂️

[@TheDisgruntledMechanic]

Yeah that's what I think too but had to give this a try 1st

[@AntonioClaudioMichael]

What up Mike good to see you brother oh no bunch of codes on the volt again

[@TheDisgruntledMechanic]

Yeah. This was possible next fix.

[@AntonioClaudioMichael]

@@TheDisgruntledMechanic if the system is off and you remove that ground strap to clean it if the modules are asleep shouldn't affect anything

[@TheDisgruntledMechanic]

Yeah I figured that but with my luck............

[@TheDisgruntledMechanic]

I know some newer vehicles all you have to do is unhook the negative cable at the battery and you have to reprogram the modules so until I would do it I just ain't sure!

[@AntonioClaudioMichael]

@@TheDisgruntledMechanic my information was based of your model and year bro but I get it your worried

[@nickcortoz8614]

What size socket is used for the bolt?

[@michaelchoo5354]

Hello Mike, Have you experienced any swerving issues? I have a chevy 2014 volt and lately when I let off the peddle, the car would swerve right and sometimes left. I thought it was the alignment and had the dealer center everything and still does the same. Hoping it is some type of sensor.

[@TheDisgruntledMechanic]

No I have not.

[@ERDALC]

I have P1E00 and P0AFA codes for my 2012 Chevy volt. What should I do? Currently it says not able to charge on main screen and power off on the secondary screen. Is there a way to clear the codes?

[@jser4822]

Hey Mike, I have a P0AC4, P0C4CF after replacing a stator bearing? Can you help any? Car will not start. Cannot clear.

[@TheDisgruntledMechanic]

the p0ac4 is emissions which shouldn't keep it from starting. and the other code I have no clue because I can not find that code because the appears too many numbers/letter in it

[@jser4822]

@@TheDisgruntledMechanic Sorry I meant P0C4F

[@TheDisgruntledMechanic]

well that 1 seems to be the code to go after because it has to do with a motor fault.

[@edwardsollis1204]

Hello Mike what is a P1E00 code?

[@TheDisgruntledMechanic]

Google is your friend here---- Control modules constantly monitor the vehicle for any condition which may adversely affect vehicle performance. If a condition is detected, the module sets a Diagnostic Trouble Code (DTC) and sends a serial data message to the Engine Control Module (ECM). The ECM sets a DTC to inform that the module has set a DTC. The serial data message sent by the module also contains a request for the ECM to illuminate the Malfunction Indicator Lamp (MIL). The DTC will be set when the ECM receives a serial data message from the Hybrid Powertrain Control Module indicating that DTC has been set in the module.

[@edwardsollis1204]

Thank you Mike , I tried erasing the code with a Innova carscan reader...but it did not...hope is not HVB. Is there any hope to get my car running again?

[@autoservice3480]

Hello I have a 2013 Chevrolet Volt and change transmission, now i cant programming it error, please can you ask me i need change transmission module or what i need doing?

[@jan-anderswesterlund2055]

I look forward to the next step. I have replaced the 12V battery and tightened the ground screw on my 2013 Volt but still have error codes from time to time.

[@TheDisgruntledMechanic]

can you tell me what codes exactly?

[@jan-anderswesterlund2055]

I have codes U184A, B, C and E. Sometimes the radio display reboots 1-4 times after startup, and works ok after that.

[@migueld4364]

Any updates?

[@TheDisgruntledMechanic]

There are codes back and I just need to see how many and what they are.

[@anthonyortega4073]

What kind of wrench was that?

[@anthonyortega4073]

What size

[@taraizal]

the codes have not returned ???

[@TheDisgruntledMechanic]

I have these codes plus many more. I have many issues with the Volt.

[@piotrkotecki4912]

Why go under the car when access to the plume is better from the top. Simply remove the engine cover and the bolt is at your fingertips.

[@TheDisgruntledMechanic]

live and learn I guess.

[@wtbm123]

Cool

[@piotrkotecki4912]

What number is of this technical biuletn ?

[@TheDisgruntledMechanic]

sorry it was not a tsb it was PI which I found in service information.

[@stevozz2]

Went to Chevy dealer here in Richmond VA and they charged me $420 to update software to fix codes, Codes came back and now they said they need to drop the battery for $1400 to see why codes came back... back against the wall... current codes are P1E00 P1EC4 P1EC6 UO140 all thoughts and idea's are welcomed! Thank you!

I assume 12 Volt battery is OK?
