Where is knock sensor 1 circuit (bank 1) 1997 land cruiser located and how do you replace it?


Knock sensor is usually screwed firmly into the middle of the cylinder block just below the head gasket. To check the circuit you will need a wiring diagram for colour codes and a pinout diagram of the ECU.

The knock sensor is basically a listening device - a microphone and they are very reliable. I had to check one once which caused me some head-scratching. The only method available to me was a capacitance comparison with a known good one using an LCR bridge. It was of course ok.
These days many inexpensive multimeters have a capacitance range...

Where does wire from crank sensor connect in an unidentified vehicle?


In a modern car, the crankshaft sensor serves only as an anti-knock sensor. When engine knock is detected the crank sensor sends its signal directly to the PCM. power control module. The wire from the sensor will undoubtedly lead through the firewall and into the PCM. If the wire has broken and you are trying to find the end, I would invest in a repair manual, Haynes has good manuals, with complete wiring diagrams. So the short answer is the wire goes to the engine control computer, the computer uses the signal to time the spark. When the engine knocks, the computer will slightly retard spark timing attempting to stop the knock. If the knock continues, the computer will light the check engine light and cause it to blink, indicating that engine damage is imminent.

I have a 2004 pilot, VTS4 and engine light came on. i have a p0325 knock sensor circ. bank A. just replace the sensor?? also i can seem to find any diagrams. any help appreciated!!!


It does sound like the sensor may be bad, but you also need to check the wiring.
This information comes from:

http://www.obd-codes.com/p0325

P0325 OBD-II Trouble Code Technical Description

Knock Sensor Circuit Malfunction
What does that mean?

A knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged. The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor wasn't operating properly, so that it was always indicating a knock, the engine computer's response may have been to change the ignition timing on your engine. Knock sensors generally bolt into or thread into the engine block. This P0325 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0330.

You may notice drivability problems including a lack of power and perhaps some hesitation. There may also be other symptoms.
Causes

A code P0325 most likely means one or more of the following has happened:

Possible Solutions
  • Check the resistance of the knock sensor (compare it to factory specs)
  • Check for broken/frayed wires leading to the sensor
  • Replace the knock sensor
