P0418 / P2445 after timing belt/water pump service

[quadforce4]

My dash lights went hog wild, and when I pulled the codes I got the following dreaded results:
P0418
P2445
C1201

The codes were listed as either confirmed, current, pending, or history which makes me feel pretty uneasy about the situation. The truck was just in for a timing belt and water pump service, is there a possibility a hose came loose or wasn't reconnected? I'll be calling the shop first thing tomorrow to see if any of this could be related.

Since that service was done a week, I've only done a very small amount of driving. Less than 50 miles easily.

Does the hewitt-tech bypass help with these codes? That seems like a good solution but my reading so far (including the FAQ linked thread) hasn't been clear on if it helps with this specific set of codes. Appreciate any info!

Additional reading on the hewitt-tech site does cover these specific codes so it seems like that may be an option. Yikes!

Could be a plug left undone....or it could be a coincidence that your secondary air pump went out right after the service.
P0418 and P2445 are both related to the secondary air injection system

I DIY'd my timing belt last month. The only connections that I would guess can give you those codes would be the vacuum hoses on and around the intake when you take it off. This guide and video will show you where to look:

Thank for you for the details on that, I am guessing it is the secondary system going bad but having confirmation that nothing came loose after the timing belt work will be good to know.

Just ran across this. I know it is months later but if anyone has any questions please contact us directly.
The P2445 and P0418 codes are codes that we can take care of but you would need a kit addon we call a Pump Proxy Pack for you P0418 code.
