Xc70 2006 130k check engine light
Code614b exhaust cam shaft reset valve
Poo27 exhaust valve control solenoid circuit low
Test drove vvt valve not responding to command
Oil was 1and a 1/2 down during scan
Light came on after reset next day. Reset next morning
26 miles driven (20 on highway)
Next day light is on again
My state emissions test is not showing any codes but states the obd is not ready to be tested
Should I drive more miles after rescanning and clearing the codes?
Thanks for your Imput and happy new year
Pete
