Car seems to be in limp mode. I'm getting o2 codes p0037, p0158, p1646, p1603
Also getting wheel sensor codes c1155, c1165, and c1175.
Any idea as to would the o2 codes or the wheel sensor codes cause a limp mode?

 

It's got to be confused so yes.

Make sure it's not your battery. If not, just fix things.

 

Quick update. I cleared the codes and now just p0037 and p1646 seem to reoccur. I'm thinking that those by themselves wouldn't cause limp mode though.
Work I've recently done was replace the battery, replace all brake pads, and we had a brake line leak and replaced a section of that. I still need to finish bleeding it though, pedal is still soft. Can the car read that?

 

Depends why it's soft but why not at least troubleshoot/fix the items flagged and the soft pedal cause rather than wonder.

 

I made the post to figure out which codes could lead to limp mode. I don't really care if the check engine light is on, providing it doesn't impact performance, such as the wheel speed sensors. I ended up buying 1 upstream and 1 downstream sensor for $150 to hopefully clear some of the codes and get it out of limp mode. At this point I really think the p0037 code is the primary issue.

Hopefully it works.

 

P0037 HO2S Heater Control Circuit Low Bank 1 Sensor 2 is between the engine and the firewall. I would check the wire first. It's PITA to get to.

thank you Dell! I actually sent this article to my team this morning to check out. It's very informative.

 

It turns out the p0037 code will cause limp mode. Replaced both sensors on bank 1 and it runs great again. On the downside it still doesn't stop well as we're struggling to get all of the air out of the rear passenger side. Confident that will come though.
