I have a 99 gt manual and my CEL came on so i had a friend put a computer on it to see what codes were coming up and i got a P0340 camshaft position sensor A bank 1 malfunction and P0500 vehicle speed sensor A malfunction. When i rev the engine it will go up to 4k and then cut out. I checked the resistance on the cam sensor and it was within limits and the air gap was fine as well. I know the speed sensor is on the trans but unsure exactly where. How can I test the speed sensor. If anyone has any ideas of what to check for please let me know.

Sorry for bringing this back from the dead, but did you ever sort out the problem? I have the exact same issue with the speed sensor and cam sensor codes, except my engine pulls to redline. I did have a temporary issue where the ecu was pulling %25 fuel regardless of the O2 sensors being plugged in or not, but now the only issue is those same two persistent codes you had.
