What is a knock sensor on a LS1?
This article applies to the Chevrolet Camaro and Pontiac Firebird (1993-2002). Knock sensors are basically small microphones attached to the engine that listen for the typical frequencies emitted from detonation. A common problem that LS1 equipped F-body cars suffer from are faulty knock sensors.
What does a LS knock sensor do?
On an older engine where the ignition timing could be adjusted, knocking could be addressed by retarding the timing a little. The knock sensor detects vibrations that come from a knock or an irregularity in combustion and send a signal to the engine control computer, which then adjusts timing to correct the knock.
Where are the knock sensors on a Camaro Firebird?
The 4th generation F-body cars that are not equipped with an LS1 V8 engine have the knock sensors located on the side of the engine block and can easily be replaced from under the vehicle. The knock sensors are located in the valley of the engine and require the intake manifold to be removed for replacement.
Can a faulty knock sensor cause a check engine light?
Faulty knock sensors will typically trigger a check engine light and prevent your engine from running at its best. Replacing the knock sensors can prevent detonation related engine damage and restore engine performance.
What to do if your knock sensor goes Kaput?
Knock sensor issues were such a problem on various GM models, GM released a Technical Service Bulletin to create a water-tight seal on the knock sensors to prevent premature failure. If the knock sensors on your LS1 equipped Camaro or Firebird have gone kaput, this article will outline the basic removal and replacement procedure.
Where is the PCV valve on a Camaro?
Disconnect the PCV valve from the front passenger side of the intake manifold by removing the 10mm nut from the pipe strap. Figure 8. PCV valve at frontside of manifold.
The 4th generation F-body cars that are not equipped with an LS1 V8 engine have the knock sensors located on the side of the engine block and can easily be replaced from under the vehicle. The knock sensors are located in the valley of the engine and require the intake manifold to be removed for replacement.
Where is the knock sensor on a car?
On a modern engine, the computer receives information from several sensors, but many engines still feature a knock sensor, usually mounted on the intake manifold or cylinder head.
Is there a knock sensor on a 95 iron headed motor?
Where using these codes might come in handy, is if you have a 95 iron headed motor, they will have two knock sensor on the block. So if you need a PCM, you should find one orignaly from an iron headed motor, so you have the correct knock sensor module.
