    1993 k1500 Engine Codes

    My truck is showing to have codes 22 and 43. It will sometimes shift bad, but I can turn it off, restart it and the shifting problems end for awhile. AutoZone told me it was the TPS sensor so I replaced it and am still having the same problems. Does anyone have any ideas on what needs to be replaced??

    Code 43 is the Electronic Spark control according to my Hanes manual.It says the probable cause would be:ESC sensor is not recieving a knock signal from the knock sensor.It says to check the knock sensor or the ESC module.
    The Hanes book explains how to do this.The book is a good investment.
    Disconect the Battery for a while to clear the codes.The 22 should go away if you replaced the tps.
