knock sensor bypass
I installed new head gaskets on my Toyota 3.0 / 3VZE and spaced changing the knock sensor (although it had not issues prior to dis-assembly). After completing the project and driving the 4-runner, the check engine light came on and I was stuck with this code. In researching the code to determine what I needed to do to resolve the problem I found that simply unplugging the sensor and leaving it for a short time had been known to cause issues and require a sensor replacement. Apparently that is standard procedure in many shops when doing head gaskets on this engine. That being said, I researched to find a way around pulling the engine back apart. What I found was someone had done some research and claimed that the displacement of this 3VZE engine was similar to a Chevy S10 4cyl and that the knock sensor was compatible. There was some controversy about the sensor being located in a bad spot and that inevitably there would be engine damage. I decided to give it a shot. It has now been 6 months, no engine light, no knocking, 16 - 19 mpg, I am happy. Thanks for watching.
