SES light came on - strange code now

boontis · Postby **boontis** » Mon Sep 11, 2017 7:02 am

So doing a casual drive over the weekend - cruising around 90kmph with the cruise on - and all of a sudden I notice the SES light is on. Nothing strange happened, no noticeable issues - but there is was. And it stayed out throughout the day and into this morning...so I finally read the code.

2 slow blinks = 2

11 fast blinks(wat?) = ?

10 fast blinks = 0

10 fast blinks = 0

I've read the code before successfully (and replaced a cam sensor

) but from what I've read there should not be 11 blinks ever?

I watched the blinks for 5 cycles just to make sure - and what I posted above is what I'm seeing.

Does anybody know what code this is? I tried searching but can't find anything for 2100 and there should be no such thing as a 21100 code?

The ses light came back on my drive home - still no apparent cause - and the code is still the same: 2 slow blinks, 11 fast, 10 fast, 10 fast?

I recommend getting a cheap code reader. They are $15.

I wonder if you have 2 codes going on.

Oh wow I didn't realize they were that cheap? Where would you recommend @disallow? (I'm in Calgary)

I found one on kijiji in calgary, listed for $25. I have the one on the bottom right of the picture. It hooks up to your Android or apple device and works great.

oh awesome thanks for looking that up for me! (I was cruising amazon but local is better

)

I've got an iPhone and see he has another add for one that will work with my device - DM already sent!

Walmart sells them, too, in the automotive section.

OK so the code is 2A00

Makes sense - 11 blinks = A I guess.

Sounds like an O2 sensor from searching but wondering if anyone else has experienced this and found it to be something else? (apparently the cats were replaced before I bought the truck - hoping it isn't those as I did see some frontier issues with cats)
