What Is the Function and Service Procedure for the Electronic Spark Control Knock Sensor on Pontiac Grand Prix?

The grown of irregular octane levels in today's gasoline is known to provoke detonation in an engine, known as "spark knock." ESC system provides ability to retard spark timing up to 15 degrees and use optimal spark advance to minimize spark knock for better drive ability and fuel economy. Knock sensor is mounted on the engine block, more specifically on an Electronic Spark Control, ESC; this sensor produces an alternating current voltage signal that it sends to the PCM and the PCM then retards the timing until spark knock is eradicated. The PCM receives an ESC signal; if this signal is somehow cut off then the PCM will constantly retard the EST, the performance will be slow, and a trouble code will be set. To remove the knock sensor follow out the cable from the negative terminal of the automobile with the Theftlock audio system lockout off if there is any. No longer epoxied to the block, remove the knock sensor electrical connector; on later-model 3800 engines, this also removes the heat-shield over the sensor. Although it would have been nice to have been informed that at least some of the screws were designed to be removed without losing their ability to be easily reinserted, remove the sensor from the block by unscrewing it, and installation is of course the reverse of the removal.

Pontiac Grand Prix Knock Sensor

Knock Sensor is very essential for the performance of Pontiac Grand Prix cars because it diagnose for engine knock mostly caused by incorrect ignition timing. This device communicates to the powertrain control module (PCM) which in turn is able to change the ignition timing to reduce on detonation. Conventionally, the knock sensors used in Pontiac Grand Prix models are piezoelectric that can effectively translate vibrations into electric signals for continuous pressures in relation to knock peaks. Many styles of knock sensors used over the years in various models of Pontiac Grand Prix may have been more focused to get improve engine performace and to avoid damage. These sensors mean that delicate fine tuning of the ignition times can be achieved- and sub-standard fuels even at lower octane ratings can also could be handled and different cylinder timings can be addressed. This technology helps the Pontiac GrandPrix perform optimally with its engine while at the same time protecting it from wear and tear occasioned by driving conditions.

Each OEM Pontiac Grand Prix Knock Sensor we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
