Hi there. The red lightning bolt is the symbol that the throttle position sensor (TPS) has failed and is no longer responding to the ECM (computer). I recommend replacing the TPS with the OEM specified part for your engine.
Listen to where the ticking noise is emitting from. If the noise is from the timing cover area, then the timing belt could be popping causing the noise. If the noise is coming behind the timing belt area, then it will be a lifter tapping for the lack of lubrication, being stuck, or the return spring inside the lifter broke. I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose the ticking noise you are hearing.
