So my sensor P0325 has been on solid for around 5 months. My mechanic buddy stated he'd fix it without the hassle of air intake, TB, exhaust mani removal. He said he had this issue with an older Toyota he owned (hard to get to sensor). What he did instead was unplug the old sensor and leave it in place. He relocated the new sensor to an unused bracket location in the engine bay, he drilled and tapped the new sensor and connected it to the same plug up the bad one was connected. My mechanic said it registered good and actually still performed its job as an knock sensor. Will provide pics when job is complete.
