HELP! Need part numbers for knock sensors and harness
Howdy all, apparently a rat chewed through the knock sensor wiring harness in my 2004 GX470. Trying to find the part numbers for the sensors and wiring harness. May as well replace the sensors while I've got the intake manifold off.... Can anybody help? Thanks in advance!

Thanks tz; but this diagram shows two different sensor types, as I've seen in various web searches. One is more of a "barrel" design that screws in, the other looks more like a chubby washer with a wire connector. Do the different banks have different knock sensors, or will either work? We bought out GX in 2003 as a 2004 model; not sure if that makes any difference. Also, any part numbers for the actual harness? Thanks!!

The 2003-2004 GX uses this screw-in OEM sensor.
89615-52010 (11/2002 - 10/2004) , xRef list here http://www.kakapart.com/search/defau...ch/89615-52010

2005 model started a new # with a bolt on sensor

The wiring for the sensors comes out of the main wire harness and attach via a connector, so are you looking for just the connectors to make repair? Any pics of the wire damage?

There's only two types, one for 2003-2004 models, and one for 2005+
If the sensors need replacing or will be replaced, then why not take the intake off and just take a look ?
