Engine Performance problem
1993 Chevy S-10 6 cyl Four Wheel Drive 198K miles
My 'check engine light' is on.&Amp; I finally found access to a computer and a get 'Code 43' (indicating a faulty 'Knock Sensor'). Apparently someone (who had worked on the vehicle previously) had broken the Knock Sensor ' Connector (END)'. And had 'taped it into position'. The Spark Knock is quite bad & after doing some research, I found the Knock Sensor Connector is part of the EST (Electronic Spark Timing System), consisting of the 'distributor HEI module' and the ECM (Electronic Control Module).
Which is MY QUESTION:
I would appreciate some direction on 'finding' the Module and replacing the Knock Sensor Connector's wire (where it's connected at the Module.
In other words, The Knock Sensor 'Connector' may be my 'entire' trouble, but I need some help on locating the 'module' and then instructions on wiring it into the system (wiring harness/module).
I thought I'd start by replacing 'just' the connector/wire. Then replace the Knock Sensor, if replacing the connector/ wire doesn't correct the problem.I just cant locate the module or any direction on wiring the connector's wire into the harness and how it connects to the module.
I guess the 'check engine light' will 'go out' after correcting the knock sensor issue(?).
Thank for your time and any assistance in this matter.
