Problem with toyota camry knock sensor switch

knock sensors on v engines are on the insides of the cylinders in the v
the wires and harness will run down the v of the engine

On the 2.4 liter four-cylinder engine it is located on the siie of the engine block (the side nearest the firewall).

On the 3.0 Liter V-6 engine there are 2 knock sensors and the are located in the "valley" below the intake manifold. You'll have to remove the intake manifold to get to them.

Hi. its somewhere under the intake manifold. quite painful to access.

code p0325 = ecm engine control moduel

Should be on the side of the block facing the firewall. It may or may not be contacting coolant so you may have to drain the radiator.
Keep in mind knock sensors almost never fail. You may have an engine component making a noise or vibration the sensor is picking up.
The sensor is supposed to sense spark knock and tell the computer to adjust the spark timing down.

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.

these sensors can go bad. and it should probably be replaced it is on the back of the engine near the top of the block

hi first try this? unbolt knock sensor and clead both engine block suface and the brass surface of sensor then re bolt to engine block do not use any grease/lube make sure the wiring to sensor+plug are clean then recheck operation of sensor ? if no joy ? renew sensor

i have toyota windom 4vz-fe i need locate knock sensor

Your sensor went off because it overknocked.
Try using a different type of fuel with a higher octane.
Erase the code and use the better gas. if it comes back then we will worry about replacing it.
