Tech Tip: Nissan Versa EVAP Codes
Perform this service procedure if a Nissan Versa’s MIL is “ON” with with certain EVAP codes tripped, and the EVAP vent control valve is stuck open or will not seal when operated/closed.
Oil-Related Engine Codes For Variable Valve Timing 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.
Converter Codes: How Long Will The Light Stay Out?
Even if the converter is operating below 95% efficiency or the oxygen sensor is bad, the chances of the light coming right back on are slim. If you clear the code, the light might stay off for a while until the system goes through two readiness cycles. This might take a couple of days or a couple of weeks. But, no good deed goes unpunished because the customer will be back and your quick fix will be forgotten.
Misfire Codes P0301 To P0312: A Look At Common Causes

OBD II O2 Slow Response Codes Technical Tip Clip
In this tech tip clip excerpt from the AVI class ‘Top 10 OBD 2 Codes: Fix Them Fast’ training program instructor Dave Scaler talks about slow response codes. Current generation o2 sensor heaters are controlled by the computer, and cars today go into closed loop faster than ever on todays cars. Dave talks about the two downsides of this situation and how they effect your diagnostic process. He goes on to further detail the diagnostic processes involved in solving O2 sensor slow codes.
