Hey guys. My cel light is on and the ecu is throwing a knock sensor code (po325). I have a 1999 4dr GSR and a Greddy turbo kit. I have already replaced the following; ecu,under dash wiring harness (the one that plugs into the ecu and goes out to the shock tower), engine harness, and knock sensor. The oil level seems to be fine. Vtec is not kicking in however. Any ideas?

 

it might be picking up knock in the cylinders

 

How are you tuned? Are you tuned at all?

 

bad gas or not using 92+ octane?

No, I'm using 92+ octane

Using the stock Greddy blue box tune (this should be fine in with a stock GSR running stock boost levels)

Oh man.... I hope not. I don't think so though because the kit has not been on the car longer then 2 weeks and I have not really boosted the engine (kept under 4000 rpm)

 

lets hope its not knocking

 

nope! wasn't. I feel like an idiot.... I had the iab plug on the knock sensor and the knock on the iab.
