P1613 Code after Gen2 Hewitt SAIS Bypass Installed

Had the Gen 2 SAIS bypass kit from hewitt installed and didn't have any codes for a while. Winter came and I got the cold weather p2445 code but it came with the p1613 code. I expected this, but the codes are persisting now that it's warm. I understand I may need a pressure sensor and to flash the ECM to get rid of the p2445 code but what about the p1613? The Gen 2 bypass kit is supposed to delete the air injection control driver, so I wouldn't expect that to be triggering anything or would that be possible? If not, what else could it be? Wiring all looks intact, no water damage either.

 

I’m gonna tag @hewitttech @HewittTech01 in this post. Their cx service is top notch. I’ve got that kit installed on my truck too.

when you clear the codes with a code reader do they immediately come back or Just after startup? I’m gonna assume at startup since that should be the only time the secondary air injection would cycle

do you have a reader that differentiates between pending and set codes? My ultra gauge 2 will sometimes show that p2445 code but the truck never actually sets it

 

Thanks for the response and tagging hewitt. I was just typing a message to them. Looking back at my scan history, looks like the p2445 has only been pending for a few months but the p1613 is confirmed.

 

I had a kinda similar issue, I installed a gen 2 bypass kit and was good for a while then all of a sudden I got 1613 2442 codes, I replaced the air control valve and the problem was still there. I ended up plugging an oem air valve and haven’t had a problem in a few days no codes and no limp mode

 

Somewhat related . . . I installed a Hewitt Bypass kit on my 2006 DC last year.
The installation went well . . . no issues.
However I got a code popping up after a while. (can't remember the code number).
It was intermittent and would, and still clears itself. The truck has never gone into limp mode.
I'm still getting the CEL light on occasion . . . then it clears itself after a few ignition starts / stops.
I spoke with their customer service, (awesome by the way) and one area of concern was the amount of wire slack I left where I tied into the trucks harness.
I did leave plenty of excess, and I'm feeling that is where the problem is.
They indicated that it is a very sensitive system that works in 'micro-volts', so the extra slack could be the source of the bug.
FWIW.

 

FYI i had a similar issue and after much trouble shooting and multiple calls with Hewitt—was starting to get frustrated, turned out the bypass kit was bad. They sent me a new one and truck has been good ever since.

 

I have an 08 4.0 Tundra and I have replaced the Gen2 Hewitt SAIS Bypass installed. I am now showing codes P1613 and P1614. Hewitt did replace the bypass kit and I am still pulling the same codes. Any thoughts on what to do next?

Update: I drove the truck this morning after I cleared the P1613/4 codes. Those same codes returned and new ones showed up P2433 and P2440. Limp mode also came back.
