The latest edition of the CounterPoint newsletter from Wells Vehicle Electronics, featuring an illustrated guide to diagnosing Nissan engines equipped with variable valve timing technology, is now available free at the new Web site.

“Nissan variable valve timing is a very popular topic among the professionals who contact our tech line for diagnostic assistance,” said Mark Hicks, Wells technical services manager. “This series is designed to help technicians build their proficiency with an oscilloscope while troubleshooting a valvetrain technology now found in millions of passenger vehicles.”

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.

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.
