SOURCE: susuki xl7 2003 stuck in park?

It might be the shiftlock. On newer cars you have to press the brake pedal in order for it to shift out of park. There is a manuel override in the owners manuel. There is a switch on the brake pedal that would need to be replaced.

How do I bypass a knock sensor on a 2000 Nissan frontier


The pcm uses the knock sensor to monitor for engine knocking, and adjusts ignition timing based on this. If there is no knock sensor present, you will wind up with a hard fault that will keep the check engine lamp on continuously. Also, the truck will go into a more conservative driving mode to prevent knocking.
The knock sensor for a frontier is not terribly expensive, but it is a pain to access on nissan v6s, under the intake manifold

How do i change a knock sensor on a 1997 Nissan Altima?


Inspect/Test/Replace


A defective knock sensor may cause engine detonation or reduced spark advance and fuel economy. When a knock sensor is removed and replaced, the sensor must be tightened to its specified torque. If the knock sensor is installed tighter than it should be, it may become too sensitive and provide an excessively high voltage signal, resulting in more spark retard than required. When the knock sensor is installed looser than it should be, the knock sensor signal will be lower than normal, resulting in engine detonation.

To replace the knock sensor:


  • Disconnect the knock sensor wiring connector.

  • Then, unscrew the sensor.

  • Remove the knock sensor.

  • Reverse the procedures to install the part.

Dtc po321 on a 94 buick park ave runs good check engine light comes on at 2nd start up i replaced;crank sensor cam sensor and modlue


po321 inthe code for the knock sensor error.look for any unusual knock type sounds, such as , noisy rocker arm, harmonic balanced rubber getting loose, or detonation from low octain fuel, or egr malfunction. check to be sure sensor wiring is ok, or that it's not unplugged.knock sensor is there to detect detonation (spark knock) so pcm can ****** timing.

Service soon light stays on.. had it checked at auto zone and came up with po327 knock sensor condition. Is this gona be an expensive car repair?


no, 30 minutes labor--you can do it yourself. part is $30. You have 2 of them. 327 is for bank 1, which is the back bank by the firewall. see picture below (the picture is bank 2, but location is same on other side).

To replace the knock sensor:
  • Disconnect the knock sensor wiring connector.
  • Then, unscrew the sensor.
  • Remove the knock sensor.
  • Reverse the procedures to install the part.

    What is a knock sensor


    here goes for a 1 Tu. this sensor detects detonation in the engine caused by a dirty piston head dirty valves and valve train. When it detects this detonation it tells the computer to ****** the timing so it does not burn a hole in the pistons, at the same tie it tells the computer this the computer adjust the fuel mixture ratio to decrease hot soak detonation which can occur after running the engine getting it hot and turning it off for 5 minutes and causing the gas to pre ignite due to the heat of the engine. This device is made of piezoelectric material which generates a voltage due to sound running threw the knock sensor, Ceramic disks wafered together and it has a preset low and high voltage low voltage is 1.0 DC VOLTS high is 4.0 volts dc WITH 5 VOLTS DC as a reference voltage for testing purposes. to see if it is working tap near the knock sensor and if it is working you will notice a variation in the running of the engine as it changes timing and fuel mix to stop detonation.

    P0332 - Knock Sensor 2 Circuit Low Input (Bank 2)

    This sensor signals the engine-control computer when detonation is detected, momentarily retarding ignition timing until detonation ceases.

    Most computer-controlled systems use knock sensors to ****** timing when the engine is experiencing pinging or knocking.


    Obviously, a faulty knock sensor produces problems that appear to be ignition-system-related. If the knock sensor system does not provide an engine detonation signal to the PCM (powertrain control module), the engine detonates, especially on acceleration.
    • The first step in diagnosing the knock sensor and knock sensor module is to check all the wires and connections in the system for loose connections, corroded terminals, and damage.
    • With the ignition switch on, be sure that 12 volts are being supplied through the fuse to the knock sensor module.
    • A quick check of a knock sensor is to watch the ignition's timing while the engine is running and the engine block is tapped with a hammer.
      • The noise should cause a change in timing.
    • The knock sensor can also be checked by tapping near the sensor and watching for an AC pulse on a DMM or lab scope.
