Code 43

[jpl603]

Hello, i have a 1995 Chevy K1500 with the 5.7L. The service engine light came on and the used a jumper wire to get the code to flash. It is coming up with code 43. one place tells me it means low voltage at electronic spark timing circuit, and another says its the knock sensor. What does it mean, please help. Thank you
