Hello all!


First off, I am new to the forums. I joined because I have an issue I can't seem to solve with my 2006 civic hybrid.


It runs and drives perfect, then after about 20 minutes it throws four codes. P060a, P16d6, P16d5, and U0100. Freeze frame data shows battery voltage at 13.8v. IMA voltage is 180v. The only issue I can find in freeze frame data is vehicle speed shows up at 158mph.


The car still runs when the codes pop up, but the brake light, engine light, ima light, as well as a steering wheel light all come on, and the car won't shift out of gear unless you hit the manual release. CVT trans is also stuck in high gear so it wont' accelerate. It does this after about 20 minutes whether the car is running, or even if the ignition is on without the car running. You have to reset the battery and let it sit for a couple of hours before you can drive it for another 20 minutes. If you reset the battery and try to drive it right away the codes will come up within a minute or two.


I put a brand new 12v battery in it, and the IMA battery was rebuilt about 800 miles ago and all cells I put in had 6AH capacity or more and showed little drain over a week. (I am saying this because I know it seems like this is an IMA issue, but as I said the IMA voltage doesn't drop below 180v when the code comes on.)


I am totally stumped and would love anyone's input and expertise. I also pulled every fuse and relay one at a time to try and force all four codes (to isolate what circuit was malfunctioning), but I nothing gives me the same codes I seem to be getting. Thanks all for your time.


BTW I live in upstate new York so the car does have some light corrosion and stuff. I did clean what grounds I could find. I am pretty good with a V-OHM meter and have a simple OBDII scanner.

Can anyone answer the above post please? same codes and exact problems as described.. Honda civic hybrid 2005. It runs perfectly for first 25 mins and if you exceed that all the lights come on.. no accleration, check engine on, Power steering and VSA. i have to stop and put the car in parking mode.. but it gets locked into there.. have to wait 1 hour for it to cool down to start the car and drive for another 5 to 10 mins before it starts again.. the longer the car cools down the longer u drive to a maximum of 20 mins.. or i have to remove battery so that it resets the system.. wait for 1 min or 2min then start the car.. went to scan it and got the codes P060A, P16D6, P16D5, U100. It describes a PCM failure.

But im having a doubt if the PCM failed it would start at all, it happens when the car has pick up heats.. though its normal temperature for the car.

Oxygen sensor or anything else??

Before anyone points to the IMA pack.. please note that the IMA batery is a new pack.

12v battery also have been changed.

So please if anyone can answer or have been able to solve this type of problem.. respond its urgent!!

Hello. I am the original poster. I diagnosed it as a bad ecm eventually. I took it to the dealer and they confirmed. I bought a used one for a hybrid on eBay for 80 bucks and towed the car to the dealer to get it reprogrammed. 10k miles later and still running great. Good luck!

Carls47807

You can determine if it's Ecm by letting car sit not running but with ignition on. Mine would light up after 15 minutes or so.

Sunnyl Isram

Yeah if it stays idle also it would light up..

Thanks pal for replying
Just a last confirmation
The 2nd hand ecm u got off ebay.. was it the same serial number or a different one.. i just saw one on ebay coming from a 2012 hybrid.. would it fit?? I know i need to reprogrammed it

Sarang,

i had the same problem that was mention at the top.

car runs ok until the engine heats up... then the dashboard lights just goes crazy.

i have put in a new Bumble Bee battery and changed out engine compartment battery (12V) too.

then i bought a OBDII code reader and pulled these codes

P16D6
P060A
P16D5

so i too a leap of faith and saw this thread and bought a Used ECU (the one that is in the engine compartment by the battery.
bought the ECU from EBAY for about 99 dollars shipped.

i drove the car when it was cold to the dealership and gave them the ECU to install into the car, also they need to program your keys into the New/Used Ebay ECU so the car can start.

anyways, after the ECU replacement, my Honda Civic Hybrid 2006 runs great ! i have 171,000 miles now.. my failure happened around 140,000 miles..
good luck !

Hi my name is Bobby and I just purchased a 2007 Honda Civic Hybrid that's experiencing the same problem and throwing off the same codes
P16D6
P060A
P16D5
After driving the car for a while it gets stuck in park and I'm not able to put it in gear. What's the name of the part do I need to order? And what's the ballpark price do you think the Honda dealership would charge me for for installation and to reprogram key??? Thank you for all your help you are the best
