Default Need the crankshaft and camshaft position sensor location on 1990 Honda Accord LX...?

She was running fine and then started idling low, and stalling out. Now she'll turn over reluctantly but won't start. Your help will be very much appreciated. Thanks.

According to the information I have, all the sensors are in the distributor and can not be changed out individually. The entire distributor needs to be changed. Quoting from information courtesy of Auto Zone: The CRANK or crankshaft angle sensor signal is used to determine the fuel injection and ignition timing. It is also used to generate the engine speed signal. The TDC sensor signal is used to determine ignition timing during start-up or when the CRANK signal is abnormal. The CYL sensor is used to detect the position of No. 1 cylinder; the signal is used to trigger the sequential fuel injection.

These sensors are contained within the distributor. The signals are generated by the rotation of toothed wheels passing through pick-up coils. In some cases, the CYL sensor is incorporated with the other two. The function of these components does not change, but if any single sensor is defective, the entire distributor must be replaced as an assembly.
