Searched through the forums and I can not find the reason for these code or if any other person have experience these same codes.

I recently installed an Weistec Catch Can (which i will be soon selling if anyone one wants). And several codes have popped up. Not sure what is causing it, but only thing i can think of is the Can. Sucks is that the cans is actually doing is job, but i hate the CEL

1. P0171 Powertrain (System too lean (Bank one)) I seen ppl with this code and really not worried about it.

2. P0745 Powertrain (Pressure Control Solenoid (A)) - Not sure what this one is

3. P2091 Powertrain (B Camshaft Position Actuator Control Circuit High Bank 1)


The last two i can not find anything on. and any guidance would be great.

Need to remove my catch can and have my car reflashed to stock from Jerry so that i can take it to the dealer.

If anyone is interested in the can i will consider and reasonable offers. Bought recently in the group buy last month. Item is in great condition, but has scratch from the wrench when installing on the fitting. Paid 400 plus shipping. Will consider any reasonable offer. Pics will be up later.

We can try to help you with this before you remove the Oil Separator. Give us a call tomorrow and we would be happy to help figure the issue out. Based on the codes, it seems there are a couple issues but both small. Thanks.

Let me state to everyone reading this thread that the Catch Can is hands down the best product i bought for my car. The quality of the product is top notch and it has caught a lot of oil.

Hi Weistec,

I called a few weeks ago and did what the tech told me to do. I had it reinstalled by local shop and had CEL since. I will call in the morning. I really appreciate the help

Is your catch can installed by bank 1? Maybe you hit or nicked something or its pure fluke.

I'm also getting the P0171 code. But this was when car was bone stock. I recently had a Weistec tune but still have this code popping up. I'm going to change bank 1 oxygen sensor to see if that's the problem....if anyone has any more info please let us know...this code has been troublesome for a few of us.

As for that catch can, I will love to take that off your hands =D! But don't think it's the issue....but as before, Weistec included, let us know what's exactly going on with these codes.

Guys, check for a vacuum leak. I had two of those codes (2091 & 0745) along with 3 more and it turned out I had a leaking intake manifiold.

In my case, dealer changed whole intake manifold and gasket and screws and still got the P0171 code in less then 500 miles, before ECU tune. But yea, intake gasket is a very known issue. Mine does a stumble after a startup with code erased. The car idles a bit rough but other then that performance and such are the same. I spoke to Weistec about this code and Anthony at Weistec recommended it may be a MAS or O2 so ill try that first before taking it back to the dealer...my pockets can't handle another visit. I also have, in the past, put 110 octane so O2 is plausible.

Good luck. Hope it gets sorted out.
