Hello and thanks in advance for any insights to my problem. Yesterday my 99 Sportage produced a loud bang and came to a rolling stop along the highway near my home. Attempts to restart resulted in popping and sputtering but it would not start.
I happened to have my code reader with me and upon checking I found codes p0137 and, more significantly, p0342. Since I had the reader I cleared to codes and tried again. This time it produced code p0336.
A little background:
The car had been throwing codes p0131 & p0137 which are O2 sensors. In an attempt to rectify this situation I finally changed out the upstream O2 sensor, cleared the codes and took a drive. This is when the failure occurred, approximately five miles from home after the sensor change. The code p0131 is now gone so at least that aspect seems to have been successful.
Does anyone think that there is any possibility that changing the O2 sensor (changed without incident BTW) could be related. It would seem not to me but...
The new codes, namely p0342 & p0336, relate to the camshaft and crankshaft positions. To a backyard mechanic such as myself this would seem to point to a failure of the timing belt and or tensioner. Does this sound correct?
I've spent years working on my own V8 vehicles and an not afraid to dig in to the sporty but these types of cars are very foreign to me.
This is my only vehicle and work on Monday morning is rapidly approaching. Can anyone help?
Resolution: A damaged/shorted crankshaft position sensor was the cause of the sudden failure. This thread also contains information on valve timing and catalytic converter failure.
