Customer Question
I have a p0016...

I have a p0016 fault code on my 2005 highlander 4 cylinder base model.. I've replace the VVT sensor but still have engine check, VSC and trac off lights on. The P0016 possible cause talk about VVT sensor circuit open or short or poor electrical connection. I.ve scraped the VVT sensor connector contacts with a very small screw driver.. How do I trouble shoot the open / shorted circuit?

Mechanic's Assistant: Does the light stay on, or does it blink?

Stays on

Mechanic's Assistant: Are you fixing your Highlander yourself? What have you tried so far?

Replaced the VVT sensor/solenoid and scraped the VVT connector terminals
