I went to Autozone and had the codes pulled. It came back as P0113 (Intake Air Temperature Circuit High Input) and P0332 (Knock Sensor 2 Circuit Low Input - Bank 2). The P0113 code came up twice. The car does not seem to be running any different (i.e. poor idle, loss of power, etc.)

Any guesses as to what causes these codes and how do I fix them?

It's a 2000 SS with SLP Longtubes, hi-flow cats, exhaust, and K&N FIPK intake. I've had the car for 2 years now with hardly any problems. It's got about 45K miles on it.

 

is your IAT sesor plugged in? maybe it took a crap on you, can't be too expensive to replace.

not sure on the other code.

if you clear them do they come back? could have just been a glitch in the system.

i've had that happen before

 

Yeah I had them cleared last night and about an hour later they popped back. Same codes. I figured it wasn't an anomaly but an actual problem that I better look into.

Where's the IAT sensor at? Can't be too hard to replace.

Because they are both electrical codes (high/low inputs) could it be a poor alternator or battery? I run 2 amps in my car but have never gotten any codes from it for the 2 years I have had the car and the system in the car?

 

The IAT sensor is the one that originally plugged into your stock airbox, check the connector and wires too.

Edit: Just in case you need it PN is 12160244 about $18 list.

 

IAT is the sensor on the left in this picture (not the one with purple)

not sure where it gets relocated to with the K&N system

 

Anybody know what causes the P0332? I have been searching for information on it but haven't come up with much.

 

Sent you a PM

 

The IAT sensor was unplugged which explains that code. I am going to get the car rescanned today and see if I am still getting the 0332 code. It might be the knock sensor gone bad.

 

did u just get your lt headers on recently?

 

I have had the headers on my car for a couple of years. I've not read about headers causing a knock sensor problem. My only thought is that the actual knock sensor has gone bad?!

I have an extended warranty on the car is that something that should be covered under warranty? The car only has 44K miles on it.
