Odb ii

Doridori, this is the first you've mentioned a code. We were all running on the understanding that your OBDII was in "not ready" mode, due to the battery change. Just simply performing a drive cycle will not solve any codes you're getting.

Have you reset the code to see if it returns? With a P0327, it's very possible your sensor is bad, but anytime you're talking about knock sensors, it's best to rule out some other variables before you just start replacing sensors.
Check the wiring to the sensor.
Check all spark plugs / coils / wires.
Check you have fresh, clean, high quality, premium fuel.
Then clear the code and see if it returns.

And yes, when you do ther drive cycle to get into ready mode, you should start cold. (First run of the day, for instance)

Hi Maytag,

When I first take the car to the smog check, the smog check report just came out "not ready". So, that's when I made the 1st post in this forum.

Yesterday, I went to an AutoZone and used their ODB II scanner to do a scan. That's how I found out about the code (p0327: Knock sensor 1 circuit low input (bank 1)).

So, seems like I have a more complicated problem than I thought.

May I know how to reset the code?

Thanks again for your wonderful help and advice. I really appreciate.
