Being on this forum, I have read many stories of camera repairs costing in the several hundreds of dollars. A major repair on your vehicle can be over $1000+. A friend drove to Sacramento, CA to visit family. He was driving his 2012 Ford Taurus, and about 150 miles from his destination, he said his check engine light come on. He had no idea what was wrong. He drove off the highway to seek out a car service repair shop. He was told they charge $75 for a scanner code check. And if they did the repair, they would deduct the $75 charge. He elected to pay the $75, to see firsthand. The code they gave him indicated he had an Oxygen Sensor problem. He decided he would continue his trip without the repair from that shop. When he returned home, he had the problem taken care of by a local mechanic shop. I told him that I own an OBD2 Code Reader, that I bought from Autozone for less than $100, because I had been in the same situation at one time or another, but not traveling. When that engine light comes on, you want to know if it is serious or not. My friend bought a new Code Reader today for $95. It will give you a clue at least, not a total pinpoint on what is wrong. Anyone owning a car that is 5 years or older, with 100,000+ miles on it, should own some type of an OBD2 code reader. And take Jumper Cables on long trips as well. He had them in his trunk.
