So winter is over and hopefully so is this "issue". Never got around to changing out the O2 sensor. After cleaning of the MAP along with a few other things, the incidence of this "unusual code" basically disappeared. I suspect as MRRSM had indicated that it is perhaps an "abnormality" associated with the MAP. In some of internet "trails", there appears to be a potential of a GM firmware update which I am thinking perhaps changes what causes the code and maybe even "correctly reports" what it should be.... but that is a guess. I am hoping that it doesn't come back or if it does, does so during better climate conditions.
P013b popped up with check engine ... :-(
- Thread starter budwich
- Start date
well my hope turned into a certainty as the code popped out again. :-(
looks like I need to focus on the o2 removal as my renewal date is in june and the "engine light" may be an issue although in ontario, there might a "one code thing" as a "get by". Anyways, the weather is better and "the china tool" showed up after 3 months of waiting (really slow boat)... so hopefully a little / lot of heat will get the darn thing out.... and my hand can reach the connector for the disconnect.

A light and code will fail the e-test. It's the I/M readiness that can have one of the components not be ready to allow a pass.
If the new sensor doesn't fix your problem, then likely your cat is dead but before spending a boatload of money on it, you could try a "cheat" to confirm.

What you do after that is between you and your lungs
You could also check the cat using a temperature gun.
