P38A Knock sensor open circuit

Jon Dor · Oct 25, 2021

Afternoon all.
OB diagnostic says my 2000 4.6 Thor has an open circuit knock sensor.
Where is this located please?
Thanks in advance for the plethora of advice that'll avalanche in response :~}
Kind regards,
Mike.

Both sides of the block below the exhaust manifolds. More likely to be a broken wire to the connector, or bad connector.

Cheers Mate.
I figured it'd possibly be a wiring issue, but had no idea where it was located.
Thanks for your input.

unless diagnostics says which one, you need to check both.

Will do.
I've ordered a new one and will fully check out wiring and connections.
Cheers!
