How does my timing look? 16712 P0328 Content

**Nebone** · 06-09-2008 10:17 PM

I've been getting this code "16712 P0328 Knock Sensor (KS) 1 -G61: High Input (sporadic)" randomly. Got it 2 weeks ago, cleared it and it came back yesterday. I feel like the car holds back when I down shift even tho its boosting like normal @16 psi (APR software on K03s).

KS 1, G61 is the Knock Sensor w/ green wire detecting knock on cyl 3 and 4. Does this code signify knocking or is the sensor malfunctioning?

I got 2 logs of WOT 2nd to 5th gear of block 3 and 20. CF looks to be in speck, but is normally higher when just cruising or taking off from a dead stop which I find weird.

Block 3 and 20 Log

Any tips are appreciated.

Afternoon Bump

You can definitely see timing retard on cyl 3 and 4 due to this code I have, but then CF goes to zero and it pulls just fine in upper gears. Temperature outside was roughly 79 and I'm on the stock side mount.

Your timing looks very different between different cylinders - is this normal? High retard on 3-4 and less on 1-2.

Another suggestion, can you log less things (take out MAF and ignition angle) and then turn up the time interval to get more data? I've only logged two-three times so I might be talking nonsense. Free bump until someone smart gets here at least.

The difference between cyl 1&2 and 3&4 is because of that code stated above. It is got G61 sensor, which is the knock sensor for cyl 3&4.

Is it knock its hearing or is it malfunctioning? I'm byuing a new sensor this week. No place stocks them.

Have you tried logging the knock sensor voltage?

I can only log up to Block 25

Whick block is it anyway?

It might be 24.

I bought a new Knock Sensor G61 (Green Plug). I'm willing to attempt this but I can't even see the sensor on the motor so this could turn ugly.

This is the sensor on cyl 3 & 4 (according to bentley).

to get to the knock sensors you will probably have to remove the intake manifold. Our cars have 2 knock sensors one between cylinders 1 and 2, then one is between 3 and 4.

and your timing looks under control, nothing to be alarmed about. I would do what mike suggests log the knock sensor voltages. this will give you an idea on what they are seeing, and give you an idea if it is working correctly
