Oil-Related Engine Codes for VVT Engines
Variable valve timing is becoming a standard system on most late-model engines because it offers higher performance from a smaller displacement engine at higher rpms. Oil plays a larger role in VVT systems. They need engine oil not only for lubrication, but also to actuate the camshafts to change the profile of the lobes. Oil
Nissan VVT Diagnostics – Boosting Engine Performance, Fuel Economy And Emissions
Due to the ability of Nissan’s variable valve timing system to provide increased engine performance, Bob Dowie offers his diagnostic, electronic and mechanical expertise for how import vehicle specialists can most effectively perform engine service.
Variable Valve Timing (VVT) Systems Play A Direct Role In Vehicle Emissions
By the early 1990s, almost all import automotive manufacturers had a successful variable valve timing (VVT) system in production. These systems offered higher performance from smaller displacement engines at higher rpm. As these vehicles exceeded their new car warranties, technicians learned the ins and outs of these systems and how regular oil changes could increase the life of VVT components. Now, the VVT is playing a direct role in vehicle emissions and the way gases are burned in the combustion camber.

Tech Tip: Kia Constant Variable Valve Timing (CVVT) Oil Control Valve Inspection
This bulletin provides information related to the Oil Control Valve (OCV) used in Constant Variable Valve Timing (CVVT) systems. If, at any time, the OCV is suspected as a cause of rough idling, poor acceleration, camshaft timing misalignment-related trouble codes, misfire-related trouble codes, etc., on a Kia vehicle equipped with a CVVT system, be sure to perform the OCV inspection procedure below before replacement.
Tech Tip: Toyota: MIL ‘On’ DTC P1349; VVTI Actuator
Under certain conditions, customers with various 2002 Camry and Solara, and 2001-’02 Highlander and RAV4 vehicles may experience an MIL on condition with DTC P1349, indicating a variable valve timing (VVTi) malfunction. In some cases, the cause of this DTC may be the VVTi actuator. Use the procedures in this bulletin to verify the operation
Lifter Deactivation
The area of contact between the lifters and cam lobes is the highest loaded surface inside an engine.
SMP’s October Release Includes 276 New Numbers
Standard and Four Seasons continue to expand their programs for hybrid and electric vehicles.
High-Ignitability Engine Designs: The impact on Today’s Ignition Systems and Diagnostics
The evolution of the combustion chamber has given us engines with more power and lower emissions. While VVT systems and GDI have gotten all the attention, ignition coils and spark plugs underwent a revolution that has made it all possible.
