The sensor is bad.
A properly-functioning knock sensor allows the ECM to advance timing until it senses a knock. It then retards timing until the knock just barely goes away allowing for optimal gas mileage.
your knock sensor could need to be replaced
Knock Sensor On your 1992 Toyota Truck Previa 2WD (2.4L FI DOHC), the Knock Sensor is located: Front seating area, center, under engine cover, passenger side of engine, under intake manifold, mounted in engine block
The knock sensor detects spark knock (aka ping), sends that signal to the engine control module (ECM), the ECM retards the timing until the spark knock stops.
it depends on what engine you have but most of them are a 5.4 or 4.6 or 4.2 and those have the knock sensors under the intake manifold on the passenger side.

There is no "knock sensor" on a 4.0L engine
This is controlled by a knock sensor.
NO it will not. If you have a knocking sound then you have trouble inside of the engine.
A bad knock sensor would illuminate the check engine light and allow the engine to ping (spark knock). The engine doesn't shift, the transmission shifts.
There are no symptoms since the knock sensor doesn't do anything unless the engine is detonating, in which case it would do nothing and you would hear it. The knock sensor code is often tripped when there is a fault in something else since it's part of the same circuit. This is considered a "ghost" error code.
The knock sesor is located, on your Isuzu 1290, at the front of the engine. The sensor screws into the engine. Wires connect the sensor to the senor light.
No. It only senses engine vibration/knock.
The knock sensor is located on top of the engine block underneath the intake.
