I am backprobing @ #13 with ecu still connected and a good ground w/black lead, operating temperature with key in run position.

No sealants used in ect sensor install

My question was would impedance at block ground basically render the ect sensor inoperable thus giving me a voltage reading with minimal resistance?

Or if the block ground I'd bad (side of block), will the voltage be zero @ 13 with same circumstances as above.
