HI, does anyone know how or have ever replaced the knock sensor on this 1.9L I was told that it was on the block by the firewall on the drivers side. I can''t seem to see it but i do see a wire running to where i think it is. anyone know the easy way other than paying someone to do it to remove and replace this?

 

The knock sensor is a single-wire sensor located in the engine block directly behind the oil filter. With the ignition key on and the engine not running, backprobe the connection checking for voltage. It should read between 1.5 and 5.0 volts. If the voltage is higher or lower, then the sensor is either open or shorted, and should be replaced.


You can test the operation of the sensor by hooking up a timing light and observing the timing marks on the crankshaft pulley. Have an assistant sharply tap the backside of the air intake plenum with a hammer. The ignition timing should momentarily retard a few degrees. If it does, the system is working properly. If the harness test was good but the marks don''t move, the sensor is probably faulty.

 

You were told wrong

A picture is worth a thousand words.

 

Ok thank you, that diagram doesnt match the 1.9 motor tho does it, the drawing part looks nothing like the actual part...
