p0325 & p0330 woes.. again

Hey TW

About a month after dropping the Supercharger on my 3.4 I started getting the infamous p0330 code.. I went all out and replaced BOTH sensors AND the harness only to have the codes p0330 AND p0325 now come in pairs simultaneously immediately after...

Should I...

1. Install the URD 7th kit?

2. Do the GM knock sensor mod?

3. Hook up my Methanol Injection?

4. Other

I'd appreciate any input. I know this issue has many threads, but hopefully over the years we now have a surefire way to rid this amber CEL for good

Definitely start off by running a colder t-sat and maybe colder plugs. My 2nd step would be to invest into the 7th injector setup. You've obviously eliminated the sensors being the issue since the codes still come up

I should have mentioned I'm running the colder plugs and the cooler T-stat already. The 7th with it's ecu piggyback and larger fuel pump are not installed yet though.. think it'll do the trick?!

thanks RR for the sale link and info

bump for another opinion or two

 

Anyone done the GM knock sensor mod in this case?!

 

Hey I am having this exact same problem with my Toyota. Shortly after I installed my supercharger I threw the knock code. I replaced both of the knock sensors and the harness going to the wires. Needless to say, after all that work the code came back, but this time with a companion, the p0300 code. I am at a loss for what to do now and was wondering if you where able to get your code fixed, and if so how.
Thanks

 

I am having a similar problem. I have replaced the knock sensor and the harness's but then the dreaded p0330 code came on again after about a month. It seems like the code only wants to trip in overdrive at low rpm's any help on what to check/do, Im all out of thoughts. O and I already have the 7th injector from urd and colder denso plugs and the upgraded fuel pump.

 

bump i have a similar issue. replace both sensors and harness but still have p0330 code. i have the supercharger in with supra injectors, 250lph fuel pump, no piggyback yet

 

Lol guys... does anyone have an answer to this problem? I'm about two fits of rage away from hooking both sensor leads to a single GM sensor screwed to the head somewhere and call it good.
I replaced both sensors and the pigtail and was EXTREMELY careful not to damage or pinch the wires in any way and I STILL got the codes after I put it together.
"Help, I need somebody! Help, not just anybody!"

 

My truck does this too after getting supercharged. I tried new sensors, wiring harness, and even an ecu. Nothing has helped. I'm not sure what else to do without dropping lots of money on spare parts.

 

Knock sensors issue... I have replaced both sensors and the wiring harness twice, I ran all the tests from sensors connections to the ECU which all checked out good. I have ordered a second ECU to see if that is the problem.(will repost once i try new ecu) The supercharger has been on for about 89,000km however i have only been owned it for the last 10,000km and this is the first time i have seen P0325 & P0330.

I had a second wiring harness and 2 extra knock sensors so I plugged them in and had them strapped over to the side of the engine bay so they could not touch anything and i got the exact same 2 codes...

Anyone have a fix yet?

 

Someone suggested I try a new mass airflow sensor, but I don't know why that would help. New spark plugs didn't help either.

 

So I'm having same problem after the supercharger was rebuilt and installed, anyone have a link, or photos, for the GM swap knock sensor installation? Or part number for GM sensor??

 

Well got the new DESNO knock sensors off eBay for 85.00 for the pair
and installed and running great again, the dealer wanted 250 each,
