So the back story is that a new timing belt pulley went bad and led to a broken timing belt. I had the heads rebuilt by a top notch machine shop and just got done with the reassembly. The engine started ok, then got rough, then got better(as the ECU adjusted). It runs, but is just a smidge rough at idle. It briefly struggles when it returns to idle from higher RPMs. What I found is that both banks are running rich at -16% trim each side. I have re-verified the timing belt timing twice - I am certain. There are no MIL codes, but a deep scan shows p0365 - camshaft sensor no signal.

I have checked all three pins on the camshaft sensor. I have a solid ground and 11.9v supply. If the sensor is not seeing the cam sprocket, the signal has 4.8v. If it is seeing the sprocket, it has 0.17v.

One thing I find odd is that the sensor gives a high pitch “beeeeeeeeeeeep” while the sensor sees the sprocket.

QUESTIONS:
1. I think these tests say that the sensor works, but the beeeeep makes me wonder. Opinions?
2. I want to verify the wire continuity from the sensor connector back to the ECU. Does anyone have the ECU pinout for a 2012 Odyssey?

 

The CMP sensor output wire (gray) goes to the PCM Connector B, terminal no. 46.

 

Thank you!
