The 3.9L V6 didn't use a knock sensor. The 3.7L V6, used in 2004 and later, had one though.

YAEEH (yet another easter egg hunt)
why do you ask. scan it and it has DTC for knock? nah, bet not.
be best to scan it, no?

usa RODEO.
GM V6 engine with their own 3.2-liter 24-valve SOHC V6
LG6 , i think ended in 1992.
or
3.2 L 6VD1/6VD1W V6 (bingo)?

YAEEH
ill toss coin, land on 6vd1

some dont have a knock sensor. the 2.6L does.
the 1998 6vd1 has one, but not 96, in usa.


I even looked at your ECU/CPM schematic,
for the V6, and it shows, no knock sensor,(usa spec car)
The EFI spark system used on your car dictates this.
as knock (KS) controls spark timing, (retards it at knock)
but some versions have no KS sensor.

if fitted its on the block top.
has 1 wire. and screws in on a simple stud .
some are under intake manifold
its just a threaded shallow hole in block,
its only a microphone device.
here is the block a real photo.
some have it , others, dont
and one more fact, it came 92 and went and came.98
facts.

clear? see red circle below?

There are three possible: CARAVAN/GRAND CARAVAN 1995-2000 3 SP FWD V6 30L 31TH A670 CARAVAN/GRAND CARAVAN 1995-2002 3 SP FWD L4 24L 31TH A413 CARAVAN/GRAND CARAVAN 1993-2003 4 SP FWD L4 24L V6 30L/33L/38L 41TE A604

i honestly have never seen a knock sensor go bad. a knock sensor detects spark knock,which is from low octane gas. if it hears this then the ecm retards the timing to stop the knock. you wont be able to hear the knock that its listening for. its like a little microphone stuck in the block. before you replace it you might want to check the plugs on the sensor itself. if they are corroded they could cause this problem.. ANYTIME you have engine codes ,always check your ground cables on the engine and the battery. i work in the marine industry and you would be amazed all the codes you can get just from having a corroded battery cable..like i said , i have never seen a knock sensor go bad..

First, I would like to mention that most knock sensor codes are not caused by the knock sensors, but a mechanical problem with the engine. The knock sensors cannot differentiate between noises caused by mechanical problems like a bad pulley bearing, bad motor mount, noisy alternator bearings, etc. and spark knock. knock sensor codes are set when the computer has retarded the timing as far as possible to compensate for ignition ping (Spark Knock) and the noise still exists.

With that said, here are the instructions.

Remove the Intake Chamber assembly.
Disconnect Injector connectors.
Disconnect the heater hose from the Intake Manifold.
Remove the 9 bolts. 2 nuts, 2 plate washers and Intake Manifold assembly.
Remove right hand engine mounting stay and water outlet.
Disconnect the following hoses and connectors:
Radiator inlet hose.
Engine coolant reservoir hose.
Engine Coolant Temperature Sensor connector.
Engine Coolant Temperature Switch connector.
Ground strap connector.

Remove the 3 bolts and right hand mounting stay.
Remove the wire band.
Disconnect the water bypass hose from the inlet housing.
Remove the 2 bolts, 2 nuts, 2 plate washers and water outlet.
Remove the 2 gaskets.
Disconnect the Knock Sensor connectors.
Remove the Knock Sensors.

Hello, The 4.9 engine does not have a :knock sensor: You set the base time with the distributor and the PCM controls advance and ****** as necessary
