REF..... code P264A - 'A' Rocker Arm Actuator Position Sensor Circuit Bank 1 I have a Toyota auris tr valvematic 2011 plate 64K on the clock… with the above fault code....... Does NOT show up all the time, it’s very intermediate however it does seem to be more active once the engine is up and running and hot (normal running temp) I'd really appreciate ANY advice ANYONE could tell me to point me in the right direction to fix this poxy problem. I’ve done huge amount of homework
