CounterPoint is a free automotive electronics, diagnostics and driveability resource developed by the Wells Tech Technical Services team. More than 40 issues of the newsletter are available via the “Wells Tech” link at www.wellsVE.com.
The new edition features the first of a two-part study of the design, operation and diagnosis of Nissan variable valve timing, or N-VCT. The article provides a detailed analysis of crankshaft position sensor and camshaft position sensor waveforms on known-good and malfunctioning vehicles to help guide technicians in troubleshooting any of a variety of common driveability complaints.
