Ethan brought SLA his Scion FRS for a check engine light.
We scanned the codes and found P0016, crank/cam position correlation-bank 1 sensor “A”. Our team learned that the VVT value for the passenger intake camshaft sprocket was out of acceptable range. The sprocket was mechanically faulty.
We removed the front timing cover, replaced the passenger intake camshaft sprocket, associated O rings, and replaced the ECM.
P0016 Fault Code
Due to this particular fault code, it burns the code into ECM memory, requiring the ECM to be replaced. Simply fixing the mechanical issues isn’t enough to keep the Check Engine Light off. The ECM must be replaced to rectify the issue, along with the sprocket.
