I got this code popping up. When I started my car today, the RPMs were jumping all around and it stalled out on me a couple times. This is what 6S said about the code.
The 6X output signal is a five volt square wave that is initially high. The signal switches
low at each of the six. 60 degrees crankshaft position (CKP) sensor pulses. The 6X signal
is used by the PCM for greater rpm resolution and in determining KS circuit (system)
(knock retard) windowing.
Diagnostic Trouble Code parameters:
DTC 19 will set if:
* Three 6X pulses do not occur between each reference pulse.
* A 6X pulse does not immediately follow a reference pulse.
