The Engine Check light goes on and off on my Subaru Impreza 2006 model. What does that mean
The Engine Check light goes on for a day then disappears for a day and so on. This
has been going on for four days. The car technician said that there may be a problem
with the catalytic converter. He cancelled the light and said that if it came back on
again I should come it to get the car fixed. It stayed off for a day. Then it came back on
for a day when he was closed and then it went off. Now it came back on. Does this
mean that there is a problem with the engine or a problem with the sensor?
