Ned help: P0221 code and "Light Sensor-Drive to Workshop" message.
Need your input on this. I know the P0221 error code is the Throttle Position Sensor. I also have a "Light Sensor-Drive to Workshop" on the display. Are these two issues related to each other? Don't know why a light sensor issue would require me to drive to the workshop?
Also, is my P0221 error more in relation to a dirty MAF? The car does have the K&Ns oiled from the factory (I haven't cleaned and re-oiled them).
TIA for your expertise.
This is for my dad's C320.
