OK, so the ECU is not happy with the cam sensor signal. That doesn't mean the cam sensor or the ECU are faulty. The sensor is cheap so it's sometimes worth just replacing it to see what happens. But you'd be a fool to take that approach with an expensive ECU.
There are several things that can cause a cam sensor code. Have you checked the voltages on the sensor connector yet to make sure the wiring is OK? Does the sensor have a good 12V power supply? Does it have a good ground, and is there 5V on the signal terminal? You'd definitely want to do that before replacing the ECU. The other thing you should check is the timing belt. If the cam shaft isn't turning that will cause a cam sensor trouble code. Again, replacing the expensive ECU isn't going to fix that.
My sister has a 2007 Santa Fe that has starting problems intermittently.
The mechanic is stumped.
It cranks without any trouble, but it won't start. All lights turn on, glow plug light turns off. It appears to be very random.
But they have found one thing that will allow the car to...
I just got a Hyundai 2007 Santa Fe SX Diesel Automatic and I've looked and tried all afternoon to connect my iPod or my phone. I really love music so it would mean a lot if I could figure out a way to play my own.
I ran out of fuel and now I ha e put fuel in the car will not start and the battery died.
I have now charged the battery but the car still will not start and just wanting to know if the fuel pump needs priming first and how I can do that?
Hi there. My 2007 Santa Fe diesel is showing a "check engine" warning light. The manual says this is EGR-related. The car drives like it is an EGR issue - we have had problems before. I just cleaned the EGR assembly and valve - they were not that dirty before the light appeared. Also replaced...
