Code P0046

[Truchrih]

I can’t date back to when exactly this code came up (P0046) but it started after about a month after I got my cold air intake. The code only pops up when I’m full throttle at around 5-6k RPMs SOMETIMES and I can even feel when it’s gonna come on . Sometimes my car feels sluggish without the code even being on my dash (I keep clearing it) but sometimes my car feels perfect and at full power. I want to fix it but I don’t even know where to start looking. Someone’s please throw some ideas

Is this the only mod in the car? Which intake is it?

Hondata tune, exhaust and intake

Hondata tune, exhaust and intake

If you want send me a log when you can and I can look it over for you. But I suspect you might have a tiny leak in your intake system.

I’m running into the same issue. Any idea? PRL intake

put the stock intake back on and see if the problem persists.

I had the same code for 2 years. Turned out to be faulty engine harness. The pin connectors on the turbo were loose causing it to throw codes. Common fault. Thankfully mine was fixed under warranty. I know a few others didn't have such good luck.

Awesome! Thank you for the info. I tighten down the clamps to my intake and inlet pipe. Both were loose. Replacing the fuse block today. I’ll check the engine harness.

Did you request a diagnostic check from Acura or told them to check the engine harness specifically?

Ask them to clear the code. After 50 miles the computer should reset.

It is usually an air leak.

It makes sense! I appreciate everyone’s help. So far after tighten up clamps on my inlet pipe, HVI intake and charge pipe, my car is running good.
