what engine, 2L or 2.5?
the be very hard, but is 100% covered in the FSM
i must use a scope to test it, do you have one?
log in to alldata.com and read the spark page.. or buy the FSM.
here it is
here is spec page
i open my 04 2.5L FSM
page 1h6 covers CMP
i see 2 scope readings,,, 2.0L and 2.5L here,
scope channel 1 to C51-3-10 (ign. trigger sig)
scope channe 2 to C51-2-13 (cam sig)
the ign, trigger is fast
the cam is slow broad square wave
the cam sig could be seen with a voltmeter.
hi/lo repeats 5v high 0v low.
the spark trigger is way too fast to see. with any slow meter.
about 2 milliseconds, 0.002 seconds. 3volt spike,
log in and read it. at alldata.com or mitchells.
why not post symptoms.?
why not post, if scanning the ECU , cranking for 5 seconds
does the ECU set , P0340sor 355s or dead RPM PID.
why not do that and see if the ECU hates the CMP?
it will in fact report even 1 dropout in 10, !!!!
do that way before scope comes out or buy one CMP.
