Ned help: P0221 code and "Light Sensor-Drive to Workshop" message.

Hey guys,

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.

The light is the sensor by the rest view mirror I believe and sometimes the kn filters oil gets the maf dirty. get some maf cleaner and clean it and clear the code to see if it comes back.

This issue was resolved by cleaning the MAF with CRC MAF cleaner and clearing the codes. Must be the K&Ns fouling the MAF??? Need to clean the MAFs on my other cars since they all have K&Ns.
