- Q:How to check and replace the knock sensor and Ignition Control Module for Chevrolet C1500 and K1500? Posted by Customer
- A:The knock sensor is responsible for detecting abnormal engine vibrations and reducing spark knock. It produces an AC output voltage that increases with the severity of the knock, which is then fed into the ECM/PCM to retard the timing. The location of the knock sensor varies depending on the year and engine application, but it is typically found on the rear of the engine block or the side of the cylinder head. To check the sensor's resistance, disconnect the electrical connector and measure the resistance between the terminal and the engine block. If the resistance is not within the specified range, the knock sensor should be replaced. To test the sensor's operation, reconnect the connector and use a voltmeter to check for an AC voltage signal while the engine is running. The voltage should increase as the engine speed increases. If no voltage signal is present, the knock sensor should be replaced. When replacing the knock sensor, disconnect the negative battery terminal and remove the distributor or oil pressure sending unit if necessary. Disconnect the electrical connector and remove the knock sensor from the engine block. Installation is the reverse of removal. For models from 1988 to 1995, the ESC module is located near the throttle body. Disconnect the negative battery terminal and detach the electrical connector from the module. Remove the mounting screws and detach the module. Installation is the reverse of removal. For models from 1996 to 2000, the knock sensor module is located in the PCM. Remove the PCM and the knock sensor module cover. Pinch the retaining tabs and pull the knock sensor straight up to remove it. To install the knock sensor module, align the tabs with the notches on the socket and press down until the retaining tabs click into place. Finally, install the knock sensor module cover and the PCM.Posted by GMPartsGiant Specialist
- Q:Is it necessary to remove the distributor from the engine for the 1999 Chevrolet K1500? Posted by Customer
