Dear All
My 2013 Cr-z Recently not functioning with drive modes. it simply not changing with mode buttons. but car drive fine as usual like i am in Normal mode

FYI - i have a damaged Oxygen sensor (2nd sensor) cable is it related to this symptom?

Thanks

Do you have a check engine light? If so the car is trying to protect itself. It is called Limp Home mode. I think I mentioned this in another thread. Are you going to repair it?

if it were me I would drive gently. Since it is only a wiring issue to an o2 sensor the car may be running lean or rich and can do damage to spark plugs etc. To be honest I am not sure what the consequences would be.

Yesterday i soldered the damaged wire, re-insulated the joint and cleared the code , luckily CHK ENGINE massage went away!!!

Now modes working as usual

Now i'm very happy :smile2:

Thanks for all

Might need to replace the O2 sensor or the wiring repair may have too high a resistance. is there a partial harness you can replace easily? Others will know what sub harnesses you would need.:frown2:

Might have to back-up, and let us know some more information..., such as other factors that caused the o2 sensor wire to fail, or what led you to the o2 sensor/wiring as the cause.

There is an under-dash fuse that you might check/replace (B12 [IG IMA] 10 A fuse,) but here's a list of DTC's and related troubleshooting pages to look up in the service manual:

P0137 pg. 11-114
P0138 pg. 11-116
P0139 pg. 11-118
P0141 pg. 11-117

If you don't have the service manual, I'll post a link here, if I can find it....or just click on my build thread link below, and there's a link on the first page, near the end of my mod listings.

Dear Litz

Thank you for the info my sensor failed because of physical damage , car hit a bump near the o2 sensor area and wires are broken,
i will check the fuse and i don't have a service manual, if you can post it , will be a great help

Thanks
Nuwan

now I think so too, but i have to make sure rest of the car is ok to change the sensor,
Wires broken from the sensor it self, original car harness is remain undamaged. if i change the sensor everything will be fine i guess 0

thanks
Nuwan

From what I can find, there should be a DTC to track down to better diagnose the problem. Can you get the DTC for the error, or call the technician to let you (me) know what DTC (Diagnostic Trouble Code) is? The sensor and wire to the connector is new, so it is either not receiving current from where it plugs into that connector, which leads to the ECM, or if you hit something hard enough to break the sensor/wiring, then I'm wondering if it was a hard enough hit to crack/damage the exhaust manifold and/or one of the catalytic converters. Bottom line, I need a DTC error code to even come up with any other suggestions that might help, otherwise, it's guess work.

Can you find a different mechanic than Mr. "Well, let's throw this part at it and see if it gets better" ?

Hey, thanks for worrying I really appreciate it. It's definitely on Limp Mode, it looks like running between eco and normal tho cause the circle stays on green most of time, of course its a little bit heavy and the only warning sign that pops up is the one about the "Emission system".

Do you have a check engine light? If so, you need to get a code reader (autozone will scan it for free for you) and have them give you the OBD2 code its throwing. Then we can narrow it down more.
