Thread: Crankshaft Sensor Code Issues P0336

my '98 gtp is scanning the exact same code... stalls when temp guage gets above the 1/4 hot level (i wait a few minutes and it will start/drive again, however, if you don't. wait long enough, it backfires and won't start).. i also lose my tach and my tcs light comes on (i presume i lose my traction control)...

i bought a new crankshaft positioning sensor in hopes that that might be it.

i haven't changed it out yet.

any updates as to what your trouble was and how you fixed it?

thanks.

sounds like a big vac leak. get some carb cleaner and spray it around all your vac lines while the car is running, when the idle jumps up, you found you leak area.
