Is the knock sensor sufficient to turn on the ck.eng. light by itself?
Had a air-temp/fuel mix sensor initially go bad, presumably fixed...the
mechanic says it is the knock sens. by itself that is activating the light.
Other sources say it in itself (k.s.) will not cause the ck. eng. light to
light. Who is right? What does the manufacturer say?
Need to scan for the codes to determine what is causing the light to go on. What 4 digit code or codes did the mechanic find?
