Sealants, Liquid Gaskets and Lubricants Containing Silicone
Damage to Mass Air Flow (MAF) sensors and Oxygen sensors may result from use of sealants, liquid gaskets, or lubricants containing silicone.
Many detailing products contain silicone.
If vehicle engine is running when spraying products which contain silicone (tire dressing, exterior and interior trim cleaner / protectants), silicone may be
drawn into the intake system and can contaminate the MAF sensor and/or oxygen sensors.
Do not use sprays containing silicone on or near running engines with a Mass Air Flow sensor or Oxygen sensors.
In addition, if using sealants or liquid gaskets containing silicone on or near the engine of a vehicle with a MAF sensor or oxygen sensors:
Always allow the silicone to cure properly before starting and running the vehicle's engine.
