zgeezer Posted January 9, 2009 Share Posted January 9, 2009 My Lm7 5.3 truck engine has three sensors mounted in the block directly behind the intake manifold. One lays flat of the block and "opens" toward the firewall (this is the cam sensor); the other is on an extension and is the knock sensor. The third is mounted vertically off the block and appears to have only one pin on the inside. I have no idea what the function of this sensor might be. Does anyone Know?
