1992 Buick Skylark 2.3L MFI SOHC Quad 4cyl

The Knock Sensor is located: Under hood, driver side, upper engine area, below exhaust manifold, mounted in engine block

Hey Alex , what would you like to know ? Your vehicle has Electronic power steering , controlled by a control module .
The electric power steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the body control module (BCM), power steering control module (PSCM), torque sensor, discrete battery voltage supply circuit, EPS motor, serial data bus, and the instrument panel cluster (IPC) message center to perform the system functions. The PSCM, torque sensor, not the EPS motor are serviced separately from each other or from the steering column. Any EPS components diagnosed to be malfunctioning requires replacement of the steering column assembly, also known as the EPS assembly.
They had a recall on these systems ! Suggest you take it to a GM dealer , Chevy , Cadillac , Buick , etc.....

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.

1. Remove the intake manifold.

1. Disconnect the knock sensor electrical connector.

1. Remove the knock sensor (KS).

Installation Procedure

.

1. Install the knock sensor.Tighten
   Tighten the knock sensor to 25 [n-m] (18 lb ft).
   
2. Connect the knock sensor electrical connector.
3. Reinstall the intake manifold.
   this is quite a job and i would not reccomend a novice mechanic to preform this repair book time is about two hours for this repair hope this helps

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.

• Remove the knock sensor.
• Reverse the procedures to install the part.

• Remove the knock sensor.
• Reverse the procedures to install the part.
• 15 ft.lbs.torque
• hope this helps.Thank You for using fixya..iluv2fish.. Ray..

located underneath the intake manifold remove it and disconnect the knock sensor unscrew the knock sensor. installation is reverse

Knock sensor replacement requires the removal of the intake manifold as the knock sensors are under it.
