OEM 3VZ Knock Sensor with Wire Harness
3VZ Knock Sensor sensor issues can be a tricky to diagnose, and replacing a sensor or harness in the vehicle is a big job. We install a new OEM sensor and harness on all of our Complete 3VZ Engines, and we wont install a 3VZ engine with out replacing both parts either. (we’ve been bitten by knock sensors to many times) We encourage anyone replacing a 3VZ Engine to replace these at the same time.
NOTE: NEVER use an aftermarket knock sensor on this engine, they do not produce enough voltage and will almost always through a P0325 code.
