Honda CRV 2003 - Knock sensor wiring diagram required #

Posted by Sean Hemming on May 13, 2014, 2:04 pm

Year of Manufacture *: 2003

Hi

I've got a knock sensor no signal fault code on a 2.0 petrol Honda CRV.

I scope the sensor & the voltage looks ok but live data shows only 0.06v at idle if I rev it I can get nearly 1 volt.

Does anyone have a wiring diagram so I can check at ECU.

there is nothing on autodata or bosch esi

thanks

ok, I found the knock sensor wire at ECU and got good signal there.

Has anyone had processor faults with these?

Hi, yes checked oil level first as have had previous problems caused by oil level on these CRV's. It was very low so topped up. Maybe worth flushing & changing?

The valve clearances also need checking regularly on these as they suffer with valve recession.
