Recently I had problems with the car that was finally resolved by replacing the MAF sensor. I used another site to find a solution and was simply told to replace one component after another. I was told to replace the ICU, the cam sensor, and the crank sensor until I finally inspected the MAF and found the heated wire was gone. To recap, I have replaced the coolant sensor, the Ignition module, the cam sensor and the crank sensor. After replacing the MAF the car ran great. No problems until two days ago when I started the car in the morning to allow it to warm up and warm up the interior since it is now cold here; about fifteen minutes idling. When I went to leave the car was running a bit rough and when I got inside noticed the check engine light was on. I turned the engine off and then restarted it. The check engine light was off then came back on. I decided to not drive the car. I check the trouble code by shorting the ADL connector and it flashed code 18. A search of the net said that was a cam/crank error. I checked the connectors and they were tight and I could see no breaks in the wiring where they enter the connector. I removed the cam sensor and checked that the magnet was in place and it is.
So, what causes code 18 and what should I do to correct it? Could the new cam sensor or crank sensor be the source? After completing the repairs I have driven the car about four weeks or so without any problems. I have even allowed the car to idle for fifteen minutes or so twice since the weather turned cold without any check engine lights coming on.
have the same problem?
