What Happens to Sensors if They are Dirty?
Car sensors can get dirty with normal use. Symptoms of dirty sensors include reduced engine power, worse gas mileage, or an engine that hesitates.
How Do Sensors Get Dirty or Damaged?
Car sensors measure and relay vital information to the ECU. Some sensors can get dirty from normal use, or fail if the car overheats or has a problem.
