Review on HY-SPEED 718-200 Exhaust Camshaft Position Actuator Solenoid VVT Valve - Compatible with Various GMC and Hummer Models by Stephen Lunn

I was dealing with a terrible P0014 code from my 2008 GMC Envoy. After replacing the vvt solenoid with an updated part no luck and the code kept installing. I added this part today and no problem. The code is gone. This is the part that should be used as the updated spring over net part is longer which causes the exhaust cam phaser to get stuck in the open position in my case. Very happy and thankful that this part worked! I changed the solenoid, sensor, changed the oil, used Sea Foam, changed the oil again and nothing. Then I inserted this part and voila! No more problems!
