Default Check engine light P0102 and P0340 solved!
Hi fellow Chevy drivers, I drive a 1997 Chevy Suburban 7.4 K2500 with 113,000mi. I would like to share that I finally solved my check engine light with P0102 and P0340 codes, MAF low freq, and Cam sensor circuit. It turns out I had an intermittent 12V to each connector. Spliced in new wire from 12V source and now works almost like new. I am happy I would love to help if anyone needs more detail.
