engine codes P0327, P0161

[pbkid]

ok guys, my VX threw some check engine codes today and so i stopped by autozone to find out what codes they were...

ok, so my VX has been throwing this one code for a while but it doesnt seem to affect the motor at all or power so i have procrastinated having it fixed...

P0327- knock sensor

i have no idea what a knock sensor is (besides guessing that it reads engine knock, but i dont have any engine knock so that would make no sense)
is this something that i can fix myself?

ok, secondly, a new code popped up today-
P0161- oxygen sensor, cyl. 1, after the catylitic (sp) converter (thats the info autozone gave me)

i did a search on this and got a thread concerning replacing the O2 sensor, is this all i need to do? or maybe one of the wires just got a little short in it, causing the sensor to fail for a second or two (the light turned off after a few minutes of driving)
i know O2 sensors aren't all that difficult to replace, so if i just need to replace it, thats fine and easy, i can do that myself (if its similar to my integra)

thanks guys

Are you filling up at the cheapest place in town, or running brand name petrol?

Just the first possibility that popped into my mind.

P0327 - KS Sensor Circuit Input Low


P0161 - HO2S Heater Circuit Bank 2 Sensor 2

Could be a connection, wire, or sensor...can't remember where the knock sensor is, or if I ever knew...
It's that pesky age thing...

ya the O2 sensor isnt that big of a deal, ill fix that and im sure it will fix that one...its just the knock sensor i dont know about...

not sure why you are throwing the code but from my understanding engine knock is premature detonation of a cylinder (go ahead and chuckle) its usually caused by bad/poor quality gas, the octane rating is an indicator of the knock resistance of the gas (89 is more likely to knock than 91) so i would start by clearing it and running some fuel system cleaner through your gas and see if that helps

You can always rent the VX from Alamo in Florida.
