I had an error code on my '97 Ranger that said it needed a new camshaft position sensor, but since the truck still ran fine I put off replacing it. One night I tried to start it, and it fired up for one or two seconds then died. The engine just clicked once when I tried to start it, and there was now an error code for "multiple cylinder misfire" in addition to the bad sensor, which I've read is a logical next thing to go wrong if your camshaft position sensor is bad.

So I got a new sensor and replaced the bad one, but it still just clicks once when you try to start it, and now shows either no OBD codes or just says "error" on my code reader. I tried sending an erase codes message and draining the power from the electrical system (while the battery was unhooked of course) to reset the ECM, but neither did anything. Does the engine timing need to be reset by a shop? Ideas? What am I missing?

    "clicks" sounds like a bad battery to me, that or the alternator is not charging the battery. charge the battery, see if it starts now.

  • Can you verify your results with a different scan tool? There was another issue here recently where the code reader was displaying errors that boiled down to just a faulty scanner. Could also be an ECU issue. I'd focus on figuring out why your scanner is failing first.

  • Moab, thanks for the advice. The battery was only weeks old buy I cleaned the terminals and tried jumping it, no luck. Aug 10, 2016 at 17:41
  • Jason C, thanks for the advice. My other scan tool is missing or stolen, but I will try to borrow one from a shop soon and try that also. Thanks. Aug 10, 2016 at 17:42

    I think it would be useful for you to mention what the exact code was
