I put a JWT ECU in my car and the check engine light came on after two days. I thought it was triggered by my transmission resistor bypass switch but it wouldn't reset. I took it to the dealer today and the reader came up with Knock Sensor and Line Pressure S/V. I know what caused the Line Pressure fault but I'm not sure about the Knock Sensor. Is the sensor bad or does it mean it's detecting a knock? If it's detecting a knock, is this being caused by my ECU upgrade? I haven't used anything less than 93 octane for about 3 or 4 months cause I knew I was getting the ECU and it recommends 93 or higher for it. I need some help with this little problem.

 

Dude. You already have posted this question in the 4-gen forum. Please do not repeat posts in other forums. Your question even has responses already.

There is a reason why this post keeps disappearing.

Thanks.
